Well having owned an s type r I figured it'd only be a matter of time before I had the infamous coolant leaks and I'd have to come asking for help. So there's a leak that is dripping from underneath the tranny, when I got underneath to look from where I found it runs from above or the top of the transmission all the way down. I don't know if there's hose above or around that area or not, fingers crossed I'm hoping it's not a crack in the block. Any help would be great

 

Coolant line under the supercharger?

Leaks are very common there.

is there any way to get to it besides having to take the supercharger off, also my heater doesn't work very well so could it also be the heater control valve? Thanks for the help

 

DCCV is miles away (see threads about it).

 

okay thanks for the help

 

Did you find the leak? I had a similar problem and it was a coolant line under the air intake at the front of the engine. The leak was at the front but coolant dripped from the rear. It is an easy check.

 

I have not found it yet but I am aware of a leak at the front of the engine, so I'll tackle that first and see if it fixes it! Thanks for letting me know!

 

Yes not much else will give a leak at the rear of the engine.

Yes the super charger must come off. You can DIY it but I was sure beat after that repair!

If you take off the supercharger consider replacing other hard to get bits such as other rubber and plastic hoses and fittings. I wish I had replaced the o rings on the fuel injectors because a mechanic says they are the source of intermittent vacuum leaks.
