Coolant Leak And Weird Screaming Sound :s

[AndreW_R32]

Hey.

my r32 gtst seems to leak coolant from god knows where. I can't see shit from where its dripping, water pump and all has been changed recently. doesnt over heat what so ever even if thrashing involved. I've checked container coolant gone missing slowly. but radiator is full. and only leaks some times :s

car doesnt seem to start first shot once i put foot down and try it starts. its like fuel isnt coming through straight away. cant remember if problem started after putting bp98 fuel in.

when i thrash the car past 4k rpm it makes a weird screaming sound, starting to think its coming from the pulley belts ( they are a little loose)

some help would be awesome.

cheers

Check and Tighten the turbo mounting bolts. May even need a new gasket

Coolant hoses under the inlet manifold are the #1 likely source of slow leak you can't find. That is unless it is internal to the motor.

Take it to a workshop and get them to pressure test the system for like $20 or free if they are nice.

They left mine over night and found the radiator to be leaking slowly

More likely to be a air leak than belts, and if that's the case, it will run extra rich - do you have more black smoke out the exhaust than usual?
