coolant issue, need quick answer please.

[Bludger]

with the koyo rad does the cap sit at the same height as the original rad? not sure if a difference in height could cause issues

Is the small hose in the overflow cut at an angle so the pipe isnt being blocked?

Possibly try lifting/lowering the overflow bottle to see if a change in height makes any difference

I'll cut it now, doubt it would make difference.

small hose diameter was 8 or 9 mm. new hoses are about 5 or 6 mm.......

make a difference?

height shouldn't be an issue, was working well for a while. but really can't tell because it has always had some leaking issue unrelated to this. so the coolant level was never stable.

Now I've fixed everything i can think of and this happens.


inside where the cap goes, it has turned black, the silver alloy has turned black where the cap seals.

will this cause sealling issue?

i wanna buy another cap but if i'm wrong, i waste more money.
