Hello guys, new here with a question

constantly spitting out water or smoke?

that could be from many things, thermostat, radiator cap, trapped air in the system

how are you temps when driving?
does it run on all 6 all the time or does it stumble

SupraaGirl is right or it could be you need to flush your radiator or have it checked.

A weak radiator cap can cause it. Get a new one, they are cheap, and you should have one anyway. And don't any of you mention those dreaded 3 letters, until all else is checked.

Well the temperature is always bang on half way.

I think it was an air lock tbh as when we topped it up it was spitting water out at us then went fine.

Its steam only, and condenses on the radiator behind it sat at an angle \

is your ign timing set to 10deg? if it's out a tooth it will play crazy with water flow & power

another idea

Andy unless you have excessive pressure in your cooling system (due to a blowing head gasket) you shouldn't ever have steam coming out of that hose . . . . so if it's not a BHG it may be the Radiator Cap as has already been suggested.

It is a special dual design, as when cooling down it opens to allow coolant to be sucked out of the overflow tank back into the radiator (if it needs it) . . as well as of course acting as a safety valve and opening if excessive pressure builds up

By the way, have you not found the UK Mk3 Supra Forum?
