Coolant Leak R32 Gtst

[nj1]

Hi all,

During a track day I have noticed coolant under the reservoir (it pools and runs down near the battery tray and onto the ground).

Is there some kind of relief under there when the coolant gets hot?

The cold coolant level is between the min/max, obviously when the coolant gets hot the level rises. In this case it's sits just above the max level.

I have previously not kept track of the coolant levels, is the leak and the location of the leak something of major concern?

**Noting that the car isn't overheating at the moment

Thanks

Check your radiator cap and rating. Replace with a newy if required.

Likely the water is getting hot and traveling down the overflow hose (or as steam)

Remove your reservoir and give it a good look over for crack/leak

Reservoir is fine, cap is also fine.

I let the car warm up and the exhaust is whitish, which indicates head gasket on the way out?

Car does run on E85

Oil colour is fine, not milky or anything

Is the overflow bottle actually overflowing? or is high g-force cornering sending it out the top of the overflow?

Your exhaust will create steam during warmup, condensation in the exhaust etc.... Does the exhaust steam smell like coolant?

Water expands when you heat it, it has to go somewhere...

Sounds like you got it hot, very hot. Not the first car to have overheating issues getting thrashed at the track.

It overflowed on the straight because the ecu cut cylinders/dropped the max allowable revs. Assuming it overflowed when that happened.

Doesn't really smell like coolant but it's hard to tell with the smell of the E85

What is the best course of action to prevent it overheating? Radiator has been upgraded to a koyorad 6 months ago.

My goal is to be able to do 20 mins of solid driving on the track without overheating.

Note the car is a dedicated track car RB20det with 380rwhp. Has all the modifications to suit.

Ducting. Close in the air flow path around the radiator so that the air has to go through the core and not around. Use corflute, grey packing foam, whatever is available and can be shaped and shoved into place.

Refit the undertray if it is not on the car.
