radiator cap
definately

!Zar! · 07-14-2008, 03:37 PM

Uhh.

Why don't you go outside and look instead of typing so fericiously in caps.

Check your thermostat, belts and, waterpump.

What fans are u running? Go buy a nismo thermostat.. Check water pump and belts and radiator cap.. Run 50/50 on coolant and water.. If it over heats i know it's hot but turn ur heater on, doing that will buy you some time or maybe even keep it cool enough to get to ur destination

Mikey88 · 07-14-2008, 10:13 PM

do you hear the boiling when you shut off the car? i hear it too

mjjstang · 07-14-2008, 10:20 PM

Probably most likely your radiator cap, if not you have bad tstat, if not, you have blockage in your radiator, if not you have blockage in your system,

Things I doubt, Waterpump, Would probably leak first to tell you its bad, Fans, belt, shit like that You should have already noticed. Change the Tstat and/or cap and report back, thanks.

if it is overheating more than likely its the thermostat, after the car heats up feel the lower coolant line if it has pressure in it and is hot then the thermostat is fine if not thats your problem. also you may have air bubbles in the coolant system. in order to eliminate them you need to fill the car half coolant half want and run it, once the thermostat has opened up pump the coolant lines with your hand to remove air, also there is a 10mm nut on the water outlet on the head, (drivers side, next to the CAS) remove this nut, once you see water coming out through the hole shut off the car reinsert the bolt and fill the radiator up until its full, cap and your done

PhopsonNY · 07-15-2008, 09:15 AM

What kind of fans are you running and are they working?

s13derfter · 07-15-2008, 04:42 PM

make sure there are no bubbles in your coolant system. just let car idle and watch for bubbles. + check fans. if not these two you might need a thermostat or waterpump. If you need to get somewere crack your hood but dont unlatch, get to a good speed fast and kill your engine coast to a light start again. freeway works best when overheating .

This is normal with a watercooled turbo. It's called a thermosyphon effect.
