    I would assume it is coolant. Its just a mini radiator. Maybe its the calm before the storm ie. Slight leak you noticed then shazam the floods will come. I think they go bad becuase of the lack of regular coolant changes. I had a 20 year old radiator go on me because of the plastic. But the core...dare i say was mint the fins were strong! No stains either. The heater core is full alloy so id imagine once the coolant system was free from degraded coolant and contaminents...in theory they could go on much longer...

    Thanks for the advice chaps - I'll have a look and report back with some pictures this afternoon.

    I am with DNK, pressure test the heater system and eliminate this most popular failure mode.

    I had a wet carpet and i traced it to the door seal, it was very difficult to trace, as the water gets in, and can be no where near where it gets onto the floor pan carpet.

    I have owned my car from new in 1995 and always used Toyota "Forlife", so this should avoid the cooling system failing/leaking.

    Good luck. Herbie.

    So, I didn't manage to have a completely thorough look this afternoon as the new alarm installation took longer than anticipated. However, we had the car idling for over an hour whilst the work was being carried out and there was absolutely no signs of a water leak. I also had a look at the coolant level, which, surprisingly, appeared full!!

    Here's a picture of the cap Scooter.

    I think the next thing to try, as kindly suggested, will be to pressure test the system and hope it doesn't explode in the process, until then, the mystery continues...

    Stock is 1.1 bar so the 1.3 bar puts a bit more strain on the old system, approx 3 psi

    Why is there any need for a 1.3 bar cap on a road car? That will just have the system under silly pressure constantly. Get a 1.1 back on there single turbo or not

    What is the extra pressure meant to do anyway? Aside from blowing up random components of the radiator system?

    Lets the system run hotter without it boiling

    A system under pressure can handle higher temperatures, and offers a higher static boiling point. ... If pressure is applied to the liquid, it must become hotter before it can boil. Pure water in a cooling system will boil (at sea level) at 212 F. At higher altitudes, atmospheric pressure is less than at sea level.

    Right, so with a single turbo, wouldn't the system run hotter than a standard twin set up?

    Not really, probably cooler if the turbo is oil cooled only

    Anyone know where I can get one? The usual suspects only seem to stock the high pressure caps...
