My cooling system refresh is coming up. How deep do I go?
I have decided to try to get the cooling system out of the way as I am just past 90k and its almost summer (in California).
My general list is below. Hope this helps anyone else looking for some part numbers. If you click on it a few times it will expand:
A few questions:
1) A manual car has how many of these little blue drain plugs (17111437361)? One for the radiator and one for below the expansion tank or....?
2) Has anyone included the coolant return hose in their overhaul (11531436410)? It goes from the bottom of the expansion tank to some plastic tube midway down the engine block. I havent seen pictures of the routing, but I am wondering how involved it is to include this in my project. It sounds like the air filter box needs to come out at least, right? Anyone who has replaced this chime in on your experience?
There are a few things on the list I wont be replacing. Auxiliary fan switch for one. I will just replace the o-ring with the alternate made of Vitron. Also wont bother with the coolant level sensor as I hear these rarely fail. I already replaced the expansion tank when I first got the car as it was seeping, so that is taken care of.
As for the pulleys/tensioners, I am debating whether I should just do the pulleys or if I should replace the tensioners as well. There doesnt seem to be a consensus that I can read on the various forums.
