Coolant Leak, Please Help

[denisonnd]

Hi

Last week I went for a short drive and floored it couple of times on high boost setting. The next day I found coolant under my car. I did not see where it came from.

I added about 1.5 liters of coolant mixture and went for a drive without revving over 4K and on a lower boost setting. I haven't lost any coolant after 100km of driving.

Do you guys know what the problem could be?

S2 RB25 ,bolt ons, Link, 300RWKW, standard internals including head gasket.

Cheers

How would we be able to find a leak without looking? Not even a picture...

Take it to a mechanic if you are worried, he should be able to pressurise the cooling system and find any leaks.

The leak is coming from a welch plug. (that's my wild guess based on no info )

[denisonnd]

I just found it is a odd that car lost so much coolant one day and nothing after that

Someone told me it could be the head gasket, but there is no oil in water.

I'll take it somewhere to check the cooling system

[Ben C34]

Head gaskets don't always leak into the oil, they can leak straight into a cylinder or out the side.

Did the car overheat? If so the coolant couldve come out the overflow bottle

[Dose Pipe Sutututu]

sounds like you boiled your coolant, does she have an oil cooler or aftermarket radiator?

[denisonnd]

The water temp was fine. It was just a normal drive except I went to red line on 2nd and 3rd once. Now I remember there was some coolant on the ground under overflow bottle and some under the engine (should have told you that before). Overflow bottle is almost empty now.

I just hope it is not lifting the head because of detonation or anything like that.

The car has aftermarket radiator, but no oil cooler.

I have the same kind of problem, only leaks sometimes when the car is turned off... Mine looks like around the back of the engine area as it drips from there. Also can't find where. I figure maybe it's a split in a hose that leaks under pressure...

Mattis for your problem i'd be checking the heater hoses as mine cracked and slowly leaked caused big problems its hard to get to but check the 2 hose connections beneath the iac valve

Similar issue on my 32R.

I "modified" an existing radiator cap so i could feed pressure from my compressor. It was simply a male air house coupling hot glued/tapped into the top of a spare radiator cap. Then set to around 9PSI which allowed me to sit beneath the vehicle whilst pressurized. Dont push any more then this through though.

In my case it appears to be the seal inside of my water pump but this was only occurring at full temp and only very rarely.

Otherwise take it to a professional and have it leak tested

yeah def check heater hoses or even the turbo coolant feed line. I had that split one time and I had to have a real search for it.

Also, if it is that, have fun changing it. it can be a doozy..

So I stopped being lazy and fixed mine. Mine was the rear part of the inlet plenum gasket had given out a bit. Pain in the ass job for a $15 fix...
