Radiator Under No Pressure, No Leaks.

[Aleckr33]

Hey guys, Iv got a problem with my standard radiator on my R33 GTST series 2.

Car doesn't overheat (80 - 88 deg C max), no coolant loss and there are no noticeable leaks from both top or bottom hoses. However when i turn the car off and check the radiator hoses there appears to be no pressure whatsoever...they are hot, but still very soft as if the car has had a cold start. I have no idea where to start looking... any help appreciated.

Thank you.

Pop the cap when its 90degs....that will tell you if it has any pressure.lol

the hoses will still be soft when hot.

i know they should be soft but this is not usually normal, iv seen and felt my radiator hoses when they are under pressure... right now they don't even bulge out like they used to. Also the radiator cap doesn't feel as hot either.

is there any water in it?

RB temp senders are shite and will tell you lies if there is no / little fluid in the system.

Iv got plenty of coolant in there, to the top of the radiator cap, if i squeeze the top hose the coolant will flow over the top, and the reservoir bottle is on the max line, hasn't moved. Power FC is reading these temps. Does it sound like anything is wrong? I hope it's not internal if there is.

no sounds fine really as long as you are not loosing coolant.

if you are concerned try a new radiator cap. yours may be stuck open but unlikely if you are not loosing coolant
