Engine Temps

[lowlux]

Just thought id ask what ppl have done about the engine temps rising when yourve put on a front mount cooler, as mines running alot hotter i need to do something about it, i was thinking first ill flush out the radiator,new coolant and colder thermostat to see if thatll work, also does any1 have a part no for the rb20det thermostat

[meggala]

I think its the nismo thrmostat

and it does drop the temp .

with my car the neddle doesnt mover the temp seem tobe fine with my cooler

Same prob here, my car now overheats after about 4 laps on the track, something that even on hot days never use to happen. I was going to cut a larger opening in the OE bar, then make some aluminium or fibreglass shrouding to direct ariflow thru the IC and radiator.

If this doesnt help i suppose i will try the thermostat ($$$ and where do i get one from) as well an ARE aluminium radiator just to be sure.

well i looked in some books at autobarn but the rb20det isnt listed sooo i wouldnt have a clue where to get 1 from but i need to know asap

I suspect someone like Just Jap in Sydney may have some. Try www.justjap.com Good luck

i fitted a thermostat from a VL to my 32 and run twin thermofans. With the stock radiator and a very big (600x300x73) fomt mount the temp stays at 80deg, in the last couple of days when it was 40+deg the temp would go up to 90 deg. This is with a new radiator and good cooling parts, so a alloy 32mm radiator is probably the way to go, but for $650+ try the other stuff first.

I noticed after I put the FMIC in that the water and oil temps are up by about 10 degrees or so.

I'm putting in a 16 inch davies craig (or is that craig davies??? ) fan in next weekend. I don't have to, but I noticed that the clutch fan is squeaking and has a slight wobble to it !!! So I'd hate to think what it is like at 6000rpm

If your worried about temps, go the thermostat, then thermo fans, then oil cooler or 32mm radiator and see how you go.

cool ill try the thermostat first see how that goes,any1 know how hard it is to change on the rb20?

One thing I used to do in my old car cause it used to always overheat in summer, was to drill a 1/8th inch hole in the side of the thermostat so it would always bleed a bit of water through slowly.

Not sure if it was a good idea, but it worked great.

In my old skyline it heated to much so i removed the thermo stat alltogether... It took the car ages to warm up but then it always stayed at 1/4 temp... basiclly just off cold..... It olny ever reached over the 1/3 area when doing a big mountain climb in summer is 2nd gear all the way at 3000+rpm all the way...

Not a good idea tho... But i need to in this model due to a very strange setup of FMIC/Radiator blah blah blah

yeah jay a guy at work told me to do that,he did that in his race car and it worked well, oh well ill try the colderthermostat first,if that doesent work ill drill

LOL cool, I'm glad I'm not the only dodgy person around

I saw a Nismo 86 degree thermostat somewhere, but they wanted about $120 or something like that for it. !!!

But then again, it did have the nismo name !!

Hmmm...44deg or whatever it was in melb the other day and i was driving around a bit - temp didn't.even move past the normal level. Was quite impressed!

The standard ECU should regulate it all pretty well assuming everything else is working.

I've got a pretty big front mount, oil cooler, 1 fan etc and aftermarket ecu etc and the temp sits at 75-78 depending on the outside air temp. On sunday's cruise where it was VERY stop start and 40 farkin degrees, the temp crept up to 81 but that's as high as it's gone AFAIK.

Is that oil temp or water temp???

My oil temp was sitting on about 90 degrees while on the highway (110km/h) and sat on around 75-80 when putting around.

The oil coolers must work pretty good (Jay put's one on his shopping/wish list!!).

i just thought of something,when i changed the turbo i cut the metal lines for the water and replaced them with rubber fuel hose,now this is working fine but because the turbo is sitting close to these lines could the turbo be heating up the water inside the rubber hoses?

I've got a 90mm I/C ,a 32mm PWR radiator and a big ass oil cooler. On hot days water temps reach 90-94 degrees. Normal days water temps are about 80 degrees. Don't know about winter yet.

Oil temps have never passed 90 degrees on the road. At the race track however, they've reached 120 degrees on 30+ days. I won't be happy until the water temp guage sits in the middle on 30 degrees+ track days.
