#354 of 399 Re: head problem way out of warranty [russ95] by dmathews3 Jun 10, 2009 (1:21 pm)
Replying to: russ95 (Jun 10, 2009 12:16 pm) remember that these new engines are run by computers and one years computer may or may not run a newer engine. I'm guessing that a 08/09 engine will NOT be compatible with his older trucks computer. I think shopping around for a good aftermarket repair place would not only be the best bet but also the cheapest. Replies to this message: russ95 (Jun 10, 2009 2:17 pm)

Replying to: dmathews3 (Jun 10, 2009 1:21 pm) Yes BUT the newer engine will not have any additional ECM controlled functions. If the inputs (sensors) are slightly different simply use the old ones. The existing ECM will quickly re-map the necessary parameters to operate the engine properly. A tiny gain might be realized by the matching year ECM but it wouldn't be noticable in driving it.  The only changes I'm sure of are: A. Upgrading the alternator output wiring & maybe the mega fuse. B. There may be differences in the exhaust port shape/location that may require the use of the later model manifold & cat's.  Looks like an easy one day install to me. Russ

Replying to: chevyman29 (Jan 07, 2009 4:12 pm) I just took my 2006 Colorado into the dealer due to rough idle also. It has 64,000 miles on it. You guessed it the head was bad. They are going to replace it for free. Would have been around $3000.00. If you have problems with your 5-cyl. engine idling rough make sure you tell the dealer that you know of this problem. Make sure the call the GM rep to see if your VIN fits into the free replacement grouping. By the way it is OK to drive it, the problem is that the valve does not seat and you lose compression at idle RPM's. The was a flaw in the main casting.

Replying to: weezy3 (Jun 11, 2009 8:35 am) I baught my 2006 5 cyl Colarado in January 2007 as a new vehicle. It runs fine now, but I only have 20K on the engine, since I own and drive two other cars. My problem is that my warranty ends in about 7 months. I don't want to be stuck with a $3000 repair bill, but I love the truck.   I called the dealer and was told that my VIN was not subject to a warranty extension at this time. I assume it was built sometime in 2006. I also called a HQ cutomer service number they gave me and was told the same.   You can bet that I will be making some more calls and inquiries before my warranty ends.   Any suggestions?Was this problem corrected on newer 06 models?
#358 of 399 I will never buy a GM again by warren62594 Jun 24, 2009 (5:32 pm)
I just picked up my Chevy COlorado from a dealership for the second time the head was bad. As you all know GM will honor the 100,000 miles under warranty. My problem 110,000 miles. As stated before this is the second time for this. The first time was at 60,000 now it is 50,000 on the new head. GM will not cover it as it is over the 100,000 mile mark. My main complaint is this is only 50,000 on the NEW head and they don't care! I got jerked around my so many people both at GM and my dealership. I was told that they can't do anything over 100,000 miles or they would have to for everyone. WHAT?!!! This is only 50,000 on this head....THAT GM KNOWS IS A PROBLEM!!!!! I was also informed that a civil lawsuit or class action lawsuit might be coming (if there are enough people) against this, as the dealership informed me that mine was one of the first vehicles to get this warrantied and that there may be more coming (like this is supposed to make me feel better about dropping $3200). Couple other funny notes about this is it was exactly the same cylinder (cylinder 2) on both heads, and both heads were produced by 2 different companies....I am thinking DESIGN FLAW!!! I am going to do everything in my LEGAL power to deter everyone I know (and ones I don't) to never buy a GM product again or visit the same dealership I did. One more thing...I also had to replace a cracked exhaust manifold with this....it just keeps getting better. Replies to this message: jpf (Jun 25, 2009 3:24 pm)

Replying to: warren62594 (Jun 24, 2009 5:32 pm) Sorry to hear about your problems. I had a similar problem years ago with a 95 Corsica that had GM's 2.2 liter push rod engine. These engines ate head gaskets. The head gasket was replaced twice under the base warranty and once under the extended warranty that I had purchased when the car was new. The head gasket was leaking again after the extended warranty had expired at about 75,000 to 80,000 miles and GM refused to fix it. I said the job wasn't fixed right three times and they still refused to fix it. I wound up trading the car in for a Saturn. At 110,000 miles your better off trading it in for whatever it's worth. Good luck.
#360 of 399 GMC Canyon Engine Tapping by myrtlecanyon Jul 08, 2009 (2:30 pm)
I have a 2006 Canyon 5 cyl I just bought with 48000 miles. At idle there is an engine tapping noise, but it doesnt sound like a knock. My mechanic said it sounds like a tapping lifter and thicker oil will quiet it. My friends said chevy trucks do it too. Has anyone else noticed this problem and does it mean anything is or will break?

myrtlecanyon,  You probably have the dreaded loose valve seat. Have a dealer check your truck. A special extended warrantee (to 100,000 miles on all Canyon/Colorado 4 & 5 cyl.) will fully cover the cost of a cylinder head replacement. Do not let them sell you anything else or charge you. Good luck, Russ

Replying to: myrtlecanyon (Jul 08, 2009 2:30 pm) Call GM HQ ASAP. In my last (and only) post on this forum, I asked if anybody knew when the cutoff date for the valve cover problem warranty for 06 models ended. I have the late 06 model with only 22K but am worried that sooner or later I will be stuck with the $3000 repair bill.   No replies yet. Looks like you may already be haveing the problem. Heavier oil is not a fix for anything.
