2005 Chevrolet Colorado Timing Chain tips

[@curtisrichards8369]

When I seen where all the bolts were on the intake I was able to get them all through the fender well using a 1/4 ratchet and stiff universal. I now have to take the timing cover off, and not sure if I have to drop the oil pan first. Got the top loose but it feels as if it still has bolts holding it. Clue?

Yes take off the pan. Which in my case required moving the exhaust and steering columns. Watch South Main Motors tutorial.

What mileage was this Colorado when it need a timing chain? How did you know it needed a chain?

Ive since sold it but it was under 200K. Daughter had it for a while and forgot engines use oil. The chain tensioner is hydraulic off the oil system. No tension and the chain ripped the guides which ended up as pieces in the pan and clogging the suction pipe. It could have just needed new guides but while I was down there.

Mine only has 110k and never gets abused (always has oil and always gets changed on time) so hopefully never have to do this. Hoping to get to 250k out of it without having to mess with timing chain.

It was over 300000. I'm sure it has been changed once before I bought it. I've never dealt with these types of engines before, it's like the built them backwards, it overheated doing 55 and wouldn't crank after cooling down. That's what made me think it just jumped time, knew for sure after pulling valve cover. Yet once I drained the oil mixed with water, I knew the engine either needed a head job, rebuild or new engine. bad thing is I can't find a new engine. So, the head gasket was blown, and bore scope showed water on top of pistons' Blowing my mind because I got out of mechanics back in 1991. Thinking Ls Now. I'm 63 and don't want this headache.
