Replaced Radiator and Thermostat - ZR-1 Net Registry Forums

...All I can say is "oh what a difference". For a measly 120 plus 15 for 180 thermostat I got a brand new cooling system. Now she runs cool as cucumber (generally center of gauge or lower). The only thing I do notice is that it wil creep up past the half mark if I do not have the A/C on - but I'm happy. I'll say one thing though, these cars a pain in the *** to burp - it took me quite awhile to lose all the air pockets.

Temp needle kept hanging around the 3/4 mark. Even though the car has 33k miles, its still 18 years old, so I figured it was time to buy new stuff.

I'm getting ready to take mine in for the same thing. Which rad did you put in, the AC Delco replacement?

Also, where in CA are you?

"Take yours in"? - with a few basic tools you can do this yourself.

I just ordered a replacement radiator through rockautoparts.....great parts vendor in my opinion.

How much garbage and grit and debries did you find in the rad shroud area?

I agree the stock replacement is fine. The key is keeping the rad area as free of debries as possible. The c4 cooling system is a bottom feeder and everything get sucked up in there.

It was filthy - and I hardly drive the damn car. I just layed the old radiator down, and you should have seen the dirt it left on the driveway when I moved it.

I did this job last summer along with a water pump replacement, I would have been surprised if you had seen anything different. Hope you thought to do the hoses while you where there. GC

Unfortunately, I am as mechanically capable as a baboon with no hands. So I have to take it in to get everything done.

I'm still trying to decide whether to put in the high capacity rad or not. I posted here asking if it was worth it and got a mixed response. Its only a $300 difference so I will probably just do it.

I am just waiting for my daily to come back from the body shop (dump truck lost it's load on the frwy and pelted me with rocks) so I can take the Z in.
