I noticed a heavy coolant leak about 10 minutes after parking car and turning off the engine. It looks to be coming from the back side of the engine I just can’t see where. I was trying to find the repair manual and coolant system diagram. I have a 2005 s type r model. Would it be the same manual as the regular s type?

 

Oh I forgot to add… no check engine light, it isn’t overheating, and temp gauge is normal

 

The coolant leak could be from the hose under the supercharger. After a cold soak overnight, refill the cooling system with DEXCOOL and use a cooling system pressure tester to pressurise the system to 1 bar and look for leaks.

Here is a link to the X202 Workshop Manual:

The so called 'valley pipe' that is under the supercharger in the V of the engine is known to fail on the STR's.

I did not want to be the first to post the bad news. So i waited and agree with suggestions above.

 

Hello Lizsmall and welcome to one of the finest forums on the planet. It's pleasing to see more lady members.
Until you get someone under the car, remove the plastic tray it's going to be very difficult to determine where the leak is from. Coolant could be running along the tray.
If it's the hose the gents above have mentioned you'll likely see coolant in the 'Vee'. Also from above, have a good look around as it could possibly be another hose or even a crack in the radiator.
It's going to be hard to tell without a close look.
The repair manual or cooling system diagram wont be a great help and don't drive an wait for the car to give you a warning!
