Overheating

[benny gtr]

I have problems with overheating at QLD raceway with my r32 gtr. Any suggestions?

[chaos]

[ferni]

overheating what? oil? water?

[ImpulR33R]

less wait = better times

Check all the usual things Quality of radiator fluid, are you losing any? Thermostat fully opening? system retaining right pressure? waterpump not too wornout? condition of radiator interior ,hoses and water passeges? oil cooler? theres a start

I have the same problem, now have a Trust Oil cooler under my desk. once I fit it (soon) I'll let you know.

Yep, GTRs run hot when giving them a bit of a hammering. I have been warned by many people now not to even think about taking the GTR to Q.R. until I have a nice oil cooler, a decent sump baffle setup, bigger oil pump, and bigger radiator. This has been told to me by Ernie (Skyline imports), Gavin Woods, Bruce (LEDA suspension) to name a few, and Sydneykid has also mentioned this. So unitil these things are completed on me car, my Sprint Events at Q.R. are over, not taking the risk.

I can get the oil temp in mine to the "near danger zone" with a quick drive through the mountains, hate to think what it could get to on the track.

trust 10 row oil coolers are good for another couple of laps i think...so u'll probably get in 4-5 laps if you're lucky

The water temp is never a prob, it's the oil temp that's the killer. On Nebo it cooks reeeeeeeeal quick...

First upgrade with a gtr if you want to do track work is a oil cooler, the temps rise hella fast if giving it alot on the track as you would.

Put your heater on.

rb26dett, you think the TRUST cooler may not be up to the task ? What experience have you had and what do you recommend ?

Squizz, I have the same problem up around Nebo, temp climbs real quick. We should organise a drive.

Sounds good. I'd love to have my beasty setup as a touge special.

Only done Nebo twice, loved both.

the oil cooler is in my car. it holds temps to just above the 70 mark on the gauge while cruising...

but when i really get into the driving, temps still creep up, albeit slower...this is all experienced on mountain runs. if u don't pay too much attention to the oil temp gauge u'll find it sitting at half in no time at all...

plus i'm running about 10 litres of engine oil with a trust sump...still the temps go up....

and the runs are done at night...hate day runs too much traffic, plus it's cooler at night...also done with heater venting into cabin...n still...problems with oil temp

What's the ambient temp in the engine bay like when the oil starts to run hot. if you can get the engine environment temp down it may help. Didn't 'Godzilla' have coolers on just about everything

Just driving normally it's bloody hot under the bonnet. Some venting may be in order...

aust spec 32 gtr has oil cooler for transfer case, that about the major difference to jdm 32 gtr. So engine/transmission/diff oil coolers are still needed (in order of preference).

I'm not sure how much the sump got heats up by the front diff and vice versa, as you can now get aftermarket front diff cover for extra oil capacity with more cooling fins.
