Coolant Leak From Passenger Side Of Engine (Under Turbo)?

[damono]

Hi,

I've had a pretty bad water leak from under where the turbo is. It empties the contents of radiator in about 20mins i think.

Ive taken the pipework off the passenger side and can see the turbo, but looks like its coming from somewhere on the underside of that.

My question is, are there coolant hoses on that side of the engine that I should look at, or water feed for turbo?

Whats the easiest way to fix?

Car is R33 GTST S1 (std turbo)

Any help would be appreciated, Cheers!

The coolant feed comes from the back of the motor, under the heater hoses, and feeds to the turbo which returns back to the block. It could be coming from the banjo fittings on the turbo itself or from the banjo fitting on the black. Also check the welsh plugs under the exhaust manifold.<br /><br />Good luck.

my bet would be Welch plug. You should be able to see pretty good from underneath the car.

Cheers guys.

Don't really have access to underneath the car.

If welch plug, can it be plugged up with some type of sealant, or do I need to change them?

Just had a look with torch and can see rusting/corrosion (has been happening for a while) which is inline with one welsh plug, but also what im guessing is a ~20mm water fitting coming off the block. Could be coincidence that the leak is happening above that them both tho

Welsh plugs are best replaced rather than "sealanted". And from my experience, do all of them at the same time - it's not like they are expensive. Sure as you get it all back together after fixing a leaking one, another will start to leak.

Yeah, you would have no hope of just wiping some sealant on the outside of it.

I always use some sealant when installing then though, just to make site they don't leak.
