all fluids are full water and antifreeze.i dont have an intake could that be the problem?i also dont have an o2 sensor in my gsr catalytic converter cause its not long enough.could that also be the problem?any suggestions on what to check or could be the problem?thanks for everyones help! BTW i do have 2.25 inch piping running straight to my stock exhaust.

 

check the lower radiator hose when the car gets to optimum temp. (half way) if its not warm/hot then its ur thermostat

does the fan kick on?
when the car is warm loosen the radiator cap, it lets out air pockets that maybe in the radiator.

if the prroblem is my thermostat,how do i fix that?does it cost a lot to fix?

 

two bolts and about 20-30 bux for the thermostate i think i havent had to change one since i got my swap.

 

cool!so other than that it couldnt be anything else?since i dont have an intake and o2 sensor none of those could be the problem?

 

if it is the thermostat why didnt it over heat before when i had my stock d16z6?why is it over heating now with my b20?

thanks man!so i should get a b20 thermostat?

 

i would guess you just need to bleed your cooling system! as mentioned above, after car is warmed up, check both hoses. If one is cold then you have air in the system that needs to be bled out.

Lmao

sorry but for some reason i thought that was funny

 

i did too... and it was that which led me to believe he's not familiar with having to bleed the cooling system after doing a swap!

are u overheating at idle or while driving?

 

while drving.yeah i didnt bleed the radiator/coolant system rite after my swap( my mistake).thanks everyone for their help. oh yeah one more thing,how do i keep my fan running while my car is on?how do i do it?

to keep the fan running, trace the two wires running to the radiator fan, shave a spot on both and twist em together. In case you didnt know, the thermostat is where the lower radiator hose connects to the block. Remove the two bolts and pop it out. Also, what do you mean you dont have an intake? Are you saying that you are running with nothing on your TB? if so, please connect a filter of some kind to that thing

 

Ahh it's like running open carb. lol it'll be fine!

 

just curious what radiator are you using? one that came stock (d16z6) or b20, are you running a b20vtec or stock b20. if you can't seem to solve your problem, I'd think about looking into a better radiator especially if you have a b20vtec (fluidyne, ITR, GSR)

 

i highly recommend wiring a toggle switch with a fuse for the fan, rather than a constant power jump!

check

actually replace
THERMOSTAT first.....
then try everything else....
just happened to me

took engine out of car 2 weeks ago....put it back in on friday car running hot....didn't think about the thermostat because it was good before i took it out....after 8 hours of troubleshooting from changing radiators to turning boost down

 

alrite everyone i replaced the thermostat and bled the coolant/radiator and after like 5 minutes of driving that **** over heated again.DAMMIT!.everything is fine when the car is idling.only when im drviving it over heats.i noticed the fan didnt turn on at all.does that mean i have a bad radiator/fan?what should i do now?BTW its a straight b20 non vtec for the person who asked above.thanks everyone.

 

if the motor before didn't over heat it shouldn't be ur radiator or fan relay so...

meter the resistance on the temp switch i believe its suposed to be between 200-400 whatever the measurement is ohms etc i dont remeber check ur helms

 

My dad's pontiac transport van has been overheating too lately and we found out that the fan didn't turn, but we susoect it could be the thermostat, or it could be electric connections.

 

As far as wire 12v constant to the fan, not a good idea, motor has to reach a certain operating temp, but will struggle with fan constantly on.. just my .02 cents

alrite but could that be the reason why my fan wont even come on?i dont think coolant is being pumped to the engine,i mean its @ the same level.hasnt even dropped an inch.

 

anyone?
