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

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.

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??? :spank: ) 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.

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

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

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'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.

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
