Water pump on my 2013, worth doing the chains while I am in there
Bought this one at 90k back in 2019, it is sitting at 187k now and honestly it has been decent to me. SLT-1, 3.6, front driver.
Coolant showing up on the gravel where I park, slow drip, and you can smell it after a longer run. Pressure tested it in the driveway and it is coming from behind the timing cover, so the pump. No overheating yet, temp sits where it always has.
I have done a pump on my old truck so the job itself does not scare me. What is bugging me is the chain question. Half of what I read says once that cover is off you may as well do chains and guides at this mileage. The other half says leave them alone if there is no rattle on cold start and no cam codes, and I have neither.
Parts wise, is there any real reason to pay for the ACDelco pump over decent aftermarket on a truck with this many miles on it. Prices are all over the place and I cannot work out what is actually different between them.
Anyone who has been in there already, did you do the chains, and did you regret it either way.
