Water coming out of rad cap

Chappers23 · 19-02-2014, 22:09

As above have a e9 when having a spirited drive it's pushing coolant out around rad cap and overflow tank is quite full as well any ideas

Not overheating
Heaters blowing hot
And no other running issues

Does it suck the water / coolant back when it cools ?

Chappers23 · 19-02-2014, 22:27

Not sure will have to double check that.

Best thing to do is check it when cold and make sure the level in the tank is just over the internal pipe . Then it should return back to that level when cold.

Do you mean in the rad or the overflow bottle?

Overflow, The Rad should be full to the brim.

The tank is to the full mark and rad is full as well. Looks like oil contamination in the overflow tank it's only recently been built using cosworth head gasket and h11 head studs by previous owner looks like may be head lift or head gasket

Head lift

Empty the tank and refill with coolant to cover the pipe and go from there ..

Have you checked the seal on the rad cap, or tried a different one? Would be a pity to assume head lift or something else that's fairly serious if all that's really needed is a new cap

I am picking up a new rad cap Tomoz to rule that out
