R34 Gtr Intercooler Question

[sinistaGTR]

Hey Guys,

I pulled my front bar off yesterday to find that half my fins on my intercooler are bent over hard and this is most likely contributing or the source of my weird overheatign problems atm. So im going to get a new intercooler.

There are heaps of coolers for the 32/33 gtr but not many other than the 2k HKS kits for the 34.

Im looking at the cooling pro ones for the 32/33 GTR. I have HKS GTSS turbos so im not after massive power.

Question is: How hard is it to mount the sensor from the std 34 GTR cooler into those and is it even nessecary.

Next: Are there any physical differences in the mounting points etc etc.

Or if someone can suggest a replacement cooler for under 1k Im happy to listen

I bet someone used a pressure cleaner on the front of your car.

use a comb or a flat blade screw driver and straighten the fins, Just thinking of it there is a tool you can buy for it, I think most refrigerator repair shops sell them

annnndddd found one

That would fantastic if half the fins werent bent over 90 degrees.

Are you talking about the intake temperature sensor?

If so, not necessary but it's not hard to do either. Just tap the holes for the screws or even get self tapping ones. Drill out the hole you need for the sensor and presto!

My sensor is hanging in the air at the moment as my cooler is not meant for the v-spec models. I'm waiting until I buy the hard piping kit then I will mount the sensor the same time the bar and cooler is off.

Greddy sell intercoolers with the sensor tappings in place as I had one on my old R33 GTR. I just had to use their blanking plate.

[paulr33]

can you define the "weird overheating problems"

i would be totally gobsmacked if bent fins caused your weird overheating problems

ie; it doesnt make sense

bent fins could marginally affect inlet/outlet air temp but your wording sounds like water temp / radiator problems

are you mixing the two up?

[zebra]

if the fins are all bent, than no air is going to get through to the radiator now is it

[paulr33]

im sure some air would still get through it

again im interested to see what these "wierd overheating problems" are

[R31Nismoid]

R34 GTRs always run hot without a decent tri-pass radiator.

So that comes as little surprise regardless of core. I'm with Paul.

[sinistaGTR]

Ok then.

I have a nismo radiator and thermostat.

The car used to run at 72-75.

It will now go to 75 then hop upto 77 then jump upto 85. If you stop it climbs up into the 90s. Once you start moving it gets back down to 80 then ever so slowly back to 75-77.

I have had it looked at by two workshops and everything seems fine to them. The cutch fan seems to throw a fair bit of air upwards but if you put your hand behind it, just doesnt feel as if its dragging much air through the radiator. Ine if the workshops put the dyno fan in front of the car and said it cooled back down then. So seems like an airflow problem. The car has been bled up a few times to elliminate air pockets, I have changed the coolant.

[sinistaGTR]

This all started aftr the turbos were put on. The plenum was also pulled off for installing the pwoer fc djetro map sensors. The lines have been looked at aswell.

[R31Nismoid]

I dont see why you are worried about 75 degrees. Nothing abnormal there at all.

[sinistaGTR]

Its the fact it always sat between 72-75 max. Now it jumps upto 77-85 then 90 if the car is sitting at the lights

[Roy]

How long you had the car for?

[zebra]

air lock in the coolant passages?

I too am with Paul now, if it is idling and getting hot than it isn't the intercooler, if you were cruising down the highway and it was doing it than yes, the cooler could be clocking air

[SargeRX8]

Maybe the warmer weather has something to do with it? The fact that you are getting rising temps when sitting at lights is not an indication that the problem is the bent fins as no air will be passing through the radiator at that time. Your clutch fan is spinning and pushing air through the radiator(or sucking, I don't know) but the fact that you drive and it cools down to 75 is an indication that air is coming through. From 90c to 75c when you start moving.... its not luck, its functioning.

Yeh im stuck on what to do. As I said the car has been bled a few times to get around an air lock.

I put my hand in near the front side of the radiator before and I could feel it sucking air through. I have had the car for about 6 months and I live in QLD so yes getting the hot weather, but still doesnt make sense for it to rise that much. Before the turbos went on it had no problem with the temps.

Oil temp is between 84-91 so that seems normal.

One of my turbo water pipes has a bit of a kink in it, but not enough to stop coolant flow.

[doo doo]

You still got the radiator fan shroud on?

[sinistaGTR]

Yeh that's still on there
