I have coolant leaking from either the filler cap or the filler gasket (Is there even one?). This is not the cap on the radiator, but is the cap on the thermostat housing.

Question 1: Is there even a filler cap gasket? There looks to me like there is one, but I don't see any for sale at www..mazdatrix.com.Go Here. For the filler cap, I would need to buy 'H', correct? And for the assembly, I would nned to get 'K', correct? But I don't see any gasket, if there is one.

Question 2: If there is a gasket, where do I get one. :|


Thx a ton.

 

There is a gasket under the black plastic part, I had to replace it about a year ago. It is the "O-ring for J & K."

Notice that there are two styles of cap assemblies on the thermostat. If yours is style K then you want filler cap H.

 

Oh. I don't really see it as an "o-ring". :p More like a gasket. :|

Thx, man.

 

So thats where that ring came from when I painted my thermostat housing/water pump ****... hm
