Post subject:  Cooling liquid G13A engine

Had to park the car now for overhaul and use my spare care instead... 3 problems now:

1)
I now and then had to fill up coolant, more than normal.

Finally found a small leakage, some rust dirt at the location.

On the G13A engine, there is a pipe running alongside the engine. It has to connections in one end: One end goes to the radiator, but there is a smaller pipe welded to it that goes to the heater core in the coupe.

Now, at the other end of the pipe, it runs into the water pump. There is leaking coolant here, also some rust.
Leakage is around the pipe and where it enters the water pump.

Any hints of how to fix it? What parts do I need to get hold of?

Have parked the car for restoration, other issues are:

-Upper door hinge has no support in the body, there is a 3x3cm hole...
-Fender is completely rusted downside.

Guess I am out of luck getting hold of fenders for MK1....?

If the coolant pipe isn't too rusted out all you need to do is pull it out and replace the o-ring that is on the end where it goes into the water pump housing.

Ah, as simple as that, will try to remove the pipe then.

Thanks!

Pipe is fastened only with a M10 bolt... pulled the piped out. O-ring defect as you said. Pipe rusted at the end, but OK.

Did not have a new O ring, dealer takes forever, so scrubbed the area clean and applied silicone gasket from tube as temp fix. Cured for two days before refilling. Looks good, mating surface is 1cm long and tight so silicone have a chance to hold tight.

No leakage, but need to get hold of a spare O ring in case of future failure.

Refilled with 50/50 coolant liquid/water.
