GM trucks. colorado truck . Hey look Chevy I have a web site too. I can say what ever I want. Like you can on yours.. I think since my truck is messed up. and since it is under warentee you should fix it. I had to put clear caulking around the window since the guys at Kelly on state got he wrong parts. Thern the guys at crumback didn't fix it. now the check engine light comes on and the guy at. Auto zones put he computer on it. and it said crank shaft. I changed the oil every 3,000 miles. it only has not yet 10,000 miles on it.
