heater leak

[Ju2f]

Hi Guys,

The heater under my T25 back seat seems to be leaking.

I think this comes from the cooling system right?
It does not seem to be leaking from the pipes may be the heating system itself.
How can I check? Is there anything to before removing it as it's part of the engine cooling system i think.

Thanks,

Julien

quite a common thing to leak, can be lever on the unit or the o ring between lever and heater core. you can clamp both hoses to it to make coolant loss minimal wihile you fix it.
