hey guys got a little overheating problem.
so i put an rb25 in my r32 a few months ago and have had this problem since then, its fine on the freeway sits between 77-80, then when i am sitting at the lights it will slowly rise the most i have seen was 95 degrees...
so first off i tried a bottle of mukout, the engine had been sitting around for a good year so i thought the galleries might need a clean out, no change.
i have done the following and have not noticed a change.
- new waterpump
- thermostat
- big 52mm alloy radiator
- multiple flushes
one observation i have made is if i leave the top hose off or look at the water in the radiator i get no water flow on idle, if i rev the engine it pours out and the water temp lowers.
what causes this??
as far as bleeding goes i think i have done enough, would air in the system cause this overheating problem im having?
