Re: 4g63 turbo motor issues
 

I just had this same problem with my Brothers car, only it is a 420a. I had to let it run with the radiator cap off and Burp the system to get all the air out of it! Runs fine and works Great now :) If you ever have this problem just turn the a/c or blower motor on inside the car and it will kick the secondary fan for a little more cooling until you can get it home and fixed....

Re: 4g63 turbo motor issues
 

That's a fairly common problem with most makes of cars. Bi-metal thermostats are pretty much the same no matter what. You'd think "well, it's sticking open, it should cool pretty well", but it sticks partially open and won't open fully so there isn't enough coolant flow. It's barely better than not opening at all; it doesn't matter how much it opens (or doesn't open) if it can't cool the car properly.

Randomly, most of the thermostat problems I've had are the opposite. They t-stat sticks fully open and then the car takes a long time to come up to temp. Especially fun when that happens in the winter, because then you have no heat for a long time and you have to fix a cooling system problem when it's cold as shit in the garage.

Glad it's fixed..!

okay thermostat is done water pump works fans are working car i think ima get a new cap on it soon

Re: 4g63 turbo motor issues
 

this is an easy fix, just never stop!! to hell with red lights, stop signs and traffic...;) but seriously, sounds like a fan problem. wiggle the fan while off, and make sure it doesnt move around much....

Re: 4g63 turbo motor issues
 

will cheek that. I changed out the cap today drove it for about 40 mins and idel for 20 to 30 and it only went to half way so it seems to be doing fine now i wish i could keep i cooler like quarter the way but shit happens

Re: 4g63 turbo motor issues
 

Halfway to what? Do you mean it's staying where it should be on the temp gauge?

Re: 4g63 turbo motor issues
 

yes thats what i mean i wish itr could stay cooler still

Re: 4g63 turbo motor issues
 

Halfway is normal enough for me.
