Small water leak - HELP!

Recommended Posts

Hi All

 

I have only joined the forum today and looking for some help. I have a 3.0 ltr twin turbo 2JZ-GTE supra and noticed after leaving a friends a small puddle of water by the drive front wheel. When I looked under the bonnet I couldn't see a water leak from any pipes or the radiator. I check the rad once it had cooled and it was still full. I checked the coolant reservoir bottle and it still had coolant in it. I decided to let the car heat up again and didn't see any water coming from the engine or leaking onto the ground. I took the car home left it running for a bit and had a look under the bonnet and not water leaking. Then i get up in the morning and there is another trail of water coming from the car. :(

 

Its as if when the car cools its releasing water from somewhere. I then checked the reservoir bottle and coolant again. Rad was full but bottle level had dropped a bit. I filled the bottle back to the middle and took it out for a drive. Its holds temperature fine even after giving it the beans. It holds boost etc.

 

After another drive I pulled up turned the car off and after 5-10 mins of waiting I couldn't see what coming from anywhere. Went out a few hours later and another trail of water. I haven't had the AC on or anything so know its not that.

 

I didn't notice a small pipe that looks like the feed for water to the turbo was a little bit orange looking the pipe itself telling me that coolant has been coming out from there. Its dry though and not wet. It had a new radiator fitted a few years ago and has barely carried any miles since fitted.

 

Any help would be much appreciated as the car seems to run fine under full boost and long drives etc but when parked up after a journey and cools down its releasing water (coolant) from somewhere.

 

I will get some pictures up as soon as i can

 

Thanks

Might just be rain water finding it's way down from somewhere high on the car? Will take it's time to get to the ground hence the illusion it's only when the car is cold that it leaks?

 

Is the water just clear? Or does it look like coolant that is leaking?

Check the water pipes to the turbos - I popped some cable ties round one of mine on my previous Supra when it happened to photo it so I remembered which one it was (bottom left of image) :)

I've had a tiny pin hole in 2 hoses last year.

 

Take the car for a drive so it gets up to temp, then turn it off and then check/watch the pipes under the bonnet maybe for next 20 mins or so. I found a fine mist spraying out from a tiny pin hole in a perished hose. Was easy to change once located.
