Hey guys. I have a 2000 g20t. its turbod. if im driving normal speed the car wont overheat. as soon as i start to drive 80plus thats when the car starts to overheat. when i let off the gas back to 60-70, then the temperature drops. can anybody help me out with this?

How hot is it getting?

No leaks, air pockets?

Does the radiator have lots of air flow? No huge intercooler blocking it?

Does it do with the a/c on only? What if you have the heat on does that help?

Does it overheat if you get on boost a lot?

I've only ran into this one time, but it wasn't a sentra. It was a clogged (partially)
radiator. I had it flushed at a radiator shop and it still overheated. It was hard pulling the trigger on a brand new one. It was in an xterra. It would idle all day and drive around town fine, but as soon as you hit the highway it would over heat. It had enough flow to keep up with low speed driving but as soon as the revs got up there it would get hot.

I've also heard on some nissans if the thermostat is stuck open they will over heat. I guess the water flows through the radiator so fast that it doesn't have time to cool, but I've never seen it.

How much boost are you running? What type of turbo setup? Do you still have a stock headgasket?
I had a similar issue like yours before, it was the headgasket.

well it doesnt matter if the ac is on or not. once i start gunning it the temperature almost gets to the H. it has a GT28RS turbo. 60 lbs injectors and the walbro fuel pump. the headgasket is stock. im only boosting 10lbs. the first thing im changing is the thermostat and also the coolant temp. sensor.

it could be your thermo or dodgy wire on the sender giving false read outs how long have you had this problem and how close to your rad is the turbo

Tstat, possibly wiring, water pump could all be culprits. I am leaning towards water pump though.

You sure you are not getting any head lift causing over heating while boosting?

neptronix

running your turbo without an intercooler? :p

^that doesnt make much of a difference any way coz i ran my old ga14 un-intercooled and temp never went above half way even on a long drive
