My dad has an 05 Chevy Colorado with a bad #1 cylinder and the whole head needs to be replaced. This is a common problem with this generation Colorado. Anyone know anybody who has a lot of experience with Chevy Colorados? Thanks.

the head is a known issue. if you have less then 100,000 miles, its still under warranty.

you can check out coloradofans.com or 355nation.net for your colorado needs.

half way thru 06 they changed the head, and went to a 3.7 ltr instead of 3.5

hope this helps

# 07123A: Special Coverage Adjustment - Engine Intake Valve Seat
(Nov 13, 2008)

Subject:
07123A -- Special Coverage adjustment -- Engine Intake Valve Seat

Models:
2004-06 Chevrolet Colorado
2004-06 GMC Canyon

THIS BULLETIN IS BEING REVISED TO ADD 2006 MODEL YEAR VEHICLES. PLEASE DISCARD SPECIAL COVERAGE BULLETIN NUMBER 07123, DATED AUGUST 2007.

Condition

Some customers of 2004-06 Chevrolet Colorado and GMC Canyon midsize pick-up trucks, equipped with either a 2.8L (RPO LK5) 4 cylinder or 3.5L (RPO L52) 5 cylinder engine, may experience a condition where the engine intake valve seats may wear, such that combustion leakage occurs. This will cause partial misfire and illumination of the Service Engine Soon (SES) light. Continued operation and resulting additional wear may eventually lead to engine idle roughness.

Special Coverage Adjustment

This special coverage covers the condition described above for a period of 7 years or 100,000 miles (160,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of
ownership. The repairs will be made at no charge to the customer.

For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after August 8, 2007 (2004-05 model year); November 13, 2008 (2006 model year) are covered by this special coverage and must be submitted using the labor operation codes provided with this bulletin. Claims with repair orders prior to August 8, 2007 (2004-05 model year); November 13, 2008 (2006 model year) must be submitted to the Service Contract provider.

Repairs must have occurred within the 7 years of the date the vehicle was originally placed in service, or 160,000 km (100,000 miles), whichever occurs first.

When a customer requests reimbursement, they must provide the following:

^ Proof of ownership at time of repair.

^ Original paid receipt confirming the amount of unreimbursed repair expense(s) (including Service Contract deductibles), a description of the repair, and the person or entity performing the repair.


If the work was done by someone other than a GM dealership, the amount of reimbursement will be limited to the amount that the repair would have cost GM to have it completed by a GM dealership.
