Problems with 2002 Chevrolet Silverado 2500HD ENGINE AND ENGINE COOLING

As millions of other complaints for this same problem my 2002 chevy 6.0ltr exhaust manifold bolt heads are snapping off and burned the gasket out which now fire shoots out the gap and the exhaust is now filling up in the engine compartment and traveling into the cab. also not to mention the emissions that are not being displaced properly and that it is ruining my catalytic converter. not only does this pose a huge fire risk the flame that shoots out is directed right at the engine coolant sensor and is burning it, someone somewhere has swept this problem under the rug it's time to address this before someone gets hurt. do it now !!!!!!!! demand a recall!!!!!!! do it now!!!!!!! *kb

I own a 2002 chevrolet 2500 hd with the 8.1 (8100 vortec) engine. i had began having problems with the engine stalling while driving periodically. it became a frequent problem. i had the vehicle scanned at a local auto parts store with no fault codes showing. i learned the crankshaft position sensor was at fault by doing some online research. i also learned the same engine had a recall in 2001 and not 2002 the fact the vehicle stalls during operation is a serious hazard . chevrolet needs to take responsibility for this and recall these vehicles . i changed my own , but chevrolet needs to fix this fast before someone dies if they haven't already ! *tr

I have a 2002 chevrolet silverado 2500hd lt ext. cab lb7 duramax 5 speed allison transmission, it has 114000 miles on it. this truck has been serviced as directed since new. the truck started using lots of fuel, at an idle it serged between 700 & 900 rpm's, and oil started blowing out the blowby tube. i have just found out that 3 fuel injectors are leaking fuel, with a possible head gasket leak,filling my crankcase with diesel, causing oil to blow out all over the truck, road and whatever else it can land on. while investigating what to do, to fix the truck i've found 3 other people i know that have duramax's, and they are going through the same problems. it's going to take me a year to save the money i need to fix this truck. i'm even going to do the work myself. in my opinion gm should be ashamed. they should at leased pay for the parts. the cheapest injectors i've found are $225.00 apiece with a $125.00 core charge. it's recomended that all 8 injectors be replaced at once. i've also been told these engines have defective head gaskets. that will cost another $600.00 for parts, and $110.00 for special tools i need to do the job. when i forked over the $40,000 cash inheritince money to buy this truck, i didn't signup for this. *tr

2002 2500hd chevy silverado stalling for the last 6 months randomly. taken to have fixed cannot identify the problem with computer scan. truck stalling on the highway many times. once truck stalls, turn off key, let set for 10 -15 seconds, restart. i guess the system resets itself. this is not safe. *tr

For the second time --last time about 3 years ago --the dealer tells me that the rear exhust manifold bolts have sheared off . i hear from other mechanics and the internet that this happens all the time on silverados . it is very expensive to repair . *tr

2002 2500hd silverado with 8.1l gas motor stalling randomly for two months now, at least 3 times a week. took it into the dealer and crankshaft position sensor was at fault, which the dealer told me the 2001 8.1l has open recall but not on 2002!! last time i drove the truck i was nearly t-boned due to the truck dying in intersection. please everyone who has had this problem report it here! we need a recall on this cps before someone dies! i had dealership fix it to the tune of $400!!!!! chevy needs to own this problem! *tr

Chevy 2002 silverado, with 8.1l engine, stalls without warning randomly. found problem code p0335 logged on diagnostic analyzer (crankshaft position sensor circuit a). contacted dealer and they informed me that there is a recall for model year 2001, but not 2002. scheduled for repair this week. *tr

Upon starting my 2002 chevrolet silverado with duramax engine to move it backwards 40 feet to hookup a trailer, i had no apparent power assist on brakes or steering. a second attempt to restart the engine and back up resulted in the same result, no power assist on steering or brakes. a third attempt to move the truck proved successful. this is first time this condition has appeared on this vehicle. *tr

Tl* the contact owns a 2002 chevrolet silverado 2500 hd. the contact stated that while driving 35 mph, the vehicle stalled without warning. the vehicle was taken to a local repair facility where the mechanic diagnosed that the crankshaft position sensor was defective. the vehicle was not repaired. the failure mileage was 90,000 and the current mileage was 94,000.

On 01/10/2010 at 2:45 a.m. we were awakened by a passer by who noticed our truck was on fire. by the time the fire department was able to put the fire out it had completely destroyed our truck, our car ,our grandsons truck and $66,000.00 damage to the house we were renting. we lost our vehicles and 90% of everything we own. it was determined to be the engine block heater in our 2002 chevy silverado 2500 hd. we have been in contact with general motors. we gave them all the fire reports from both west valley city fire department as well as the report and pictures provided by the investigator. they do not claim any responsibility for the fire and will not compensate us for our loss. *tr

I currently drive a 2002 chevy silverado 2500hd with an 8.1l engine. i've now taken my truck into four different mechanics for the same issue. my truck will randomly shut off the engine. i've had it shut off at stoplights, at highway speeds, driving around town, and everything in-between. occasionally, it won't even start. it sounds like it wants to turn over but to no avail. and when it stops, it takes about 5 minutes to finally get it restarted and driving again. of course, no mechanic can ever figure out what's wrong since it won't act up in the shop. i've had them tell me it could be a host of things from air problems to fuel line problems to electrical issues. no one can give me a straight answer. i've even had one mechanic drop my fuel tank to inspect the pump to see if it's the problem. even then, nothing acted up. there now is a code showing up saying my crank sensor is faulty. almost every mechanic is convinced it's my fuel pump but i have great pressure in the lines. i've noticed several people with my same year and engine have had similar issues. as well, i noticed there was a recall for the crank sensors on 2001 models but not 2002 models. why is this? i think there's just as many issues in that year as there are in following years. this issue can be a real problem if i lose power steering and wreck due to the engine shutting off! how is this not a recall for 2002 and yet a recall for 2001? i have yet to see a ses light go on for this issue. i've got just over 100,000 miles on this truck. please tell me that this will be a recall or at least this is the issue surrounding my problems! *tr

While driving down the road the vehicle dies out, and quits running. it then becomes hard to steer and stop. it takes about 2 to 5 minutes before starting back up, sometimes maybe even longer. it dies out any where from 2 to 3 times a day, depending on how long and far i am driving. the speed varies from 10 mph up to 75 mph. *tt

Tl*the contact owns a 2002 chevrolet silverado 2500 hd. while driving 60 mph, the vehicle stalled and shut off completely. there was no power steering and the brakes were stiff. the vehicle restarted after a couple of minutes and the contact drove to his residence. the dealer performed a diagnostic and stated that the crank sensor was faulty and rendered failure code number p0335. the contact paid for the repair. the failure mileage was 98,696.

I have the 2002 silverado 2500hd with the 8.1l engine and i have random stalling while driving at any speed or even standing at a stop light. it has just started to not start from a cold start too. i brought it to the dealership and was told it was giving the crankshaft position sensor code as defective. there is already a recall on specific 8.1l for the 2001 silverado with the exact same symptoms. *tr

I have a 2002 chevy silverado 2500hd with a 8.1. two months ago the truck just stalled while i was driving it and then immediately re-started. since then there have been several occasions where the truck simply shuts off while i am driving. it has become progressively difficult to restart the engine. i stalled out in the middle of an intersection the other day and sat there for 2-3 minutes trying to start the truck. there seems to be no rhyme or reason to when or why this happens. my engine light has never been tripped by this problem. after reading the trouble codes and consulting with several mechanics we determined the problem to be the crank shaft position sensor. as i read through complaints on this website i notice this is a fairly common problem. it is also very dangerous. with the amount of complaints and the level of danger associated with this i would hope this would be recalled for the safety reasons. *tr

Crankshaft position sensor is operating intermittently causing vehicle stalling during normal driving. this failure is so far random and may or may not occur each time the vehicle is driven. no ses light accompanies this failure. so far engine will restart after 10-15 seconds with key off. this failure seems similar to nhtsa campaign # 07v521000 addressing the same issue on the previous model year of this vehicle. this failure has been ongoing for the past several months and seems to be occurring more frequently lately. *tr

While driving under normal highway conditions, the engine has stalled three times in two weeks. this causes a loss of power steering and power brakes. at this point i have been able to safely pull off of the road, as it has not occurred during congested traffic. while searching the database i found similar failures of 2001 8.1l engines that were recalled to replace the crankshaft position sensor. *tr

2002 chevrolet silverado equipped with duramax diesel engine, fuel injector bodies cracked filling engine crank case with diesel fuel. i found the condition before any damage could occur. if this condition was not caught like i did, the fuel in the oil would over flow from the engine crank case and spray under the vehicle potentially causing a fire. vehicle was taken to chevrolet dealership where the fuel injectors are being replaced by a special campaign. dealer was reluctant to replace fuel injectors due to not meeting all conditions mandated by gm. gm has extended warranty for this problem to 7 years or 200k miles, but has not done a recall. these fuel injectors have an extremely high failure rate and many leak fuel into the crank case which could be a potential fire hazard. *tr

We own a 2002 chevrolet silverado ls 2500 hd with allison trans. & vortec 8100 8.1 liter v8 engine. the check-engine light was coming on, the engine ran rough, and sometimes stalled completely, usually after starting up from a stop. our dealer replaced the crank sensor and we have had no problems since. however, we recently heard (and found information on your website) that 29 of 2001 chevy or gmc models had a recall for crank sensors (nhtsa #ea06016). is an investigation under way for the 2002 models? who do we need to contact? *tr

2002 2500hd silverado with 8.1 engine. two times it cranked with no start. two other times it shut off at highway speeds with no warning of any kind. changed the fuel pump and fuel filter. finally changed the crank sensor. the sensor fixed the problem. *jb

2002 chevrolet 2500hd w/ 8.1l gasoline engine: the failure of the crankshaft position sensor on these engines appears to be a very common problem. this sensor failed on my truck at only 30k miles! i know of two other '02 trucks w/ this engine that also had the sensor fail and many others have been discovered while doing research on this problem! the seriousness of the problem lies in the fact that the truck suddenly stops running for no reason and you lose all power for the brakes and steering. at times it will restart without any problems once you shift to neutral, but other times it may not restart for a day or more. this was a huge safety issue for me since i tow a 10k lbs. fifth-wheel with the truck! my truck stopped running four times over the course of two weeks as a result of this problem. everytime was while traveling in traffic, with only one of the times while being stopped at a light! my truck is no longer under warranty due to the time limit of 36 months expiring. to have such a part fail with only 30k miles on the engine is outrageous. one of the other trucks i know of had the sensor fail around 55k miles. same problem, it would just stop in traffic or when pulling out of a light or stopped turn. again, a huge safety issue!!! the costs to me to repair my truck follow: ac delco replacement crankshaft sensor - $69.26 tow charges to tow to joseph chevrolet, cincinnati, oh - $58.85 labor due to the original sensor breaking in the block! - $336.54 total cost to replace the sensor after only 30k miles! = $464.65 again, i have to repeat how large a safety issue this is on these trucks!!! the engine just stops for no reason at any time, highway, slow moving, stopped, etc. it may restart, but then again it may not for many hours! the trucks with these engines in them are generally towing large trailers behind them. this compounds the safety aspect of the problem. *jb

Chevy silverado 2500 hd w/ 6l engine-- problem with throttle sticking. carbons up every two months around throttle valve and throttle sticks. then takes excessive throttle pressure to try to move. ---is a serious safety issue when moving in tight quarters. chevy has issued service modifications for 5.3l and 4.8l engines for same problem but has ignored the 6.0l. cleaning the carbon works for only two months then problem recurs. chevy should make a field fix like the other models before someone gets hurt. *jb

I purchased a 2002 chevrolet hd2500 with a 8100 liter engine. i have now been told that this engine will use 1 quart of oil for each 1,000 miles driven. i believe that this is an excessive amount of oil to be used in a new vehicle. has chevrolet done anything to correct this mistake. is there a recall for this problem?

While driving the vehicle at 50mph engine will start loosing or gaining power. dealer has been notified. please provide further information. ts

Loud hard knocking noise coming from engine at cold start up. then after engine is warmed up after driving and deceleration you can still hear the knocking noise, just not as loud as at cold start. taken to dealership, and advised chevrolet was aware of problem, and did not have a solution. advised by dealer it would not hurt engine, but i disagree, the very hard knocking can not be good for the valves, or crankshaft, and has to be causing some sort damage within the engine itself.

8.1 liter engine noise. also belt noise, belt has been replaced 3-times.
