Hey guys i'm gettin a weird temperature problem from my SR20VE. My temperature is rising very high and when the fans come on it goes down almost to normal. This only happens when i stop sudden or when i'm iddling for a period. If i drive it goes down to normal doesn't matter if i drive fast or slow it stays at normal but as i say when i stop the it goes up. Also i'm gettin something like a "cut", the car jus dies down and suddenly picks up again. I dont know if that could be the problem causing the rise in temperature ? Changed the thermostat and none of the hoses seem to be collapsing. What do youa"ll think ?

change your radiator to a 3 core ( my guess) and the cut is your speed limiter. Once you get it at 180 that is.

ok what u should check to see firstly is if ur VVL is engaging also it could be a faulty dashboard sensor or a faulty sensor on ur engine taking the info to ur dash i feel is one of them sesnors any good mechanic can check that for u all u need is a volt meter
but u can do what i did at that time let it raise open d overflow and stick ur finger in if it real hott then is a over heat otherwise it is just a sensor
I too had that same problem

Try puttin water in d radiator..it helps Mr. Green

Radiator could be bad in which case you should do like d sentraman say and change to a 3 core.Thermostat sould be stickin causing heat build up or temp sensor could be bad and giving ECU wrong reading.

Did you bleed your cooling system recently, if air pockets are in the system the temperature can rise considerably, what I usually do is start the car with the rad cap off and let it run till the engine is warm and ensure that all the air pockets are gone then replace the cap.

Thanks alot guys for the info. I did buy a brand new thermostat and the radiator is brand new from Massy and i did bleed the system also. Someone told me that it could be a fuse. Ok JWT how do i check the vvl. I assume it's working because i hear it when the rpm goes up. How else do i know for sure ?

Ok fellas i got it. The rise in temperature and sudden cut was because the NEGATIVE wire on the battery pole was loose and that i didn't have an ENGINE GROUND.
