So I brought another Hhr, this is my 3rd for my company and they are great cars. This one has a blown engine (valve drop or timing jump). Anywho I have a replacement engine with 76k miles. What is the recommended items that I should change while the new engine is not in yet? Timing chain? Water pump?

i don’t want to go crazy, I’m looking to get 3-4 years out of it or 60k miles.

2011 Hhr 2.2 LS. Currently says 67k, those damn valves.

 

What engine did you get for it?

 

2009 Cobalt 2.2 LE8, they used my vin to get the right engine. 8th digit on vin is W.

correction - new engine has 92k miles.

 

I would think about timing chain and guides. Look at the guides, at least.

 

Thermostat. Only the AC Delco brand.

 

Timing and balance shaft chains, guides and tensioner and a new water pump, Cloyes kit 9-4201SAWP and thermostat AC Delco 131-158. Then a new upper motor mount, and don’t forget a replacement upper timing chain bolt, Dorman 917954 and four new AC Delco 41-103 Iridium spark plugs.
