1997 Subaru Domingo CV 1.2 coolant issues

    Hello everyone, I'm a newbie to the forum having just bought a 1997 Subaru Domingo CV Japanese import to the UK (model E-FA7, engine EF12). I'm also having overheating problems, though mine manifests itself when stopping as a bubbling of coolant out of the radiator pressure cap and a hot rubber smell to the rear right-hand side of the vehicle. The temperature gauge seems to sit mid-range whilst driving.
    I asked one of my Japanese friends to translate the warning sign near the radiator pressure cap and he provided the attached. My question is this: where exactly is the 'drain hose plug which is in front of spare tyre' as it does not seem obvious to me! Any help of advice gratefully received. Thanks, Ade - macuserade@aol.com

    Have you swapped out the rad cap? if coolant is coming out of the cap you may just have a bad seal, not holding pressure. If the vehicle is overheating the rad cap will eventually open to release the pressure, this is how it should work. Is your thermostat stuck closed? a blown head gasket would/can force compression gasses into the coolant tank. If you take the overflow hose from your expansion tank and stick it into a clear jar of coolant you should not see bubbles coming out of the hose. Water pump not working, I know on the suabru Justy the water pump is a weak point.... I hop this helps.

    so ....
    -Check rad cap
    -Check thermostat
    -Ensure Rad fan is actually working (uses siganl from coolant temp sensor)
    -Water pump?
