Ok so I just had an oil change and newer radiator put in the car. Temp was fine for a while and fans would come on at 230 degrees. Now, if the car idles for about 5-10 minutes, the temp goes into the red and the fans don't even kick on anymore. Is this a T-stat issue or water pump? With this valvoline oil i have in it now, I have lower oil pressure and higher temps...anyone know whats going on?

Fans should definitely be kicking on in an overheat situation - see if you can find your answer at http://shbox.com/1/4th_gen_tech2.html#cooling

No oil out there should make the car overheat,some might run warmer cause of friction differences,but not make it completely over heat.

If your car overheats quickly within about 5-10 minutes after a cold start up,it could be your t-stat,but check into getting your fans fixed first.The link above should tell you where to start.Good luck.

sweet, so it is either my temp gage, a sensor reading in the water pump,temp, or cyclinder head sensor, or fan situation?

any shop should be able to figure this one out right?

Since your fans aren't coming on try jumpering the pins at the DLC, that'll tell you immediately if it's a fan fuse or relay.

yea well im a newb, i don't know how to do that. do i have the 12 or 16 pin? i think it is 12 but not sure. how do u jump them and which ones should i jump?

LT1Formula26

if i need a new tstat, should i switch to 160 or just go 210?

2001NBMZ28

You should have a 12 pin, just connect a wire between A & B on the port.

Well Get 160 if it gets that hot..

LT1Formula26

ok ill see what i can do about getting a 160 stat. the cooler the engine is, the more power and responsiveness it seems so...

I need get 160 Also But winter coming so it won't matter.

LT1Formula26

True, maybe I will wait for a 160 for next summer.

ok so got the car to the shop and we jumped the fan relays and got the fans to kick on (yay), so then all i needed was a new coolant sensor for the fans and my car is running great. also, there was a huge air pocket in the radiator. but car is running good, so im happy. took the guys at the shop 2.5 hours to figure this out, so they only charged me for a half hour of work and a 9 dollar sensor.
