Hi guys,

 

just finished reassembling the engine after replacing the valves on a 1.2 6v. I now have a leak from the coolant regulator and I can’t get it to stop. The bolts are as tight as possible and on zap7 there is nothing for a gasket. Am I missing something? 

 

Thanks

I guess the original o-ring has lost its elasticity, so is struggling to seal against the end face of the head. Was that face smooth and clean?

I'll try to find a part number, hang on.

 

 

 03C121119D, item 26 here: https://skoda.7zap.com/en/cz/fabia/fab/2005-453/1/121-121075/#26

Turns out that o ring has completely buggered off at some point 😂😂😂

Oh, that would explain it.  May have a spare I could post to you?

 

Thanks @Wino I’ve got my mate at TPS chesterfield to order me one, will pick it up tomoz morning and hopefully the car will be Mobile again. Really annoyed me this morning as the engine is running better than ever now lol.

All done an no leaking! Thanks for your quick response yesterday @Wino would have took me some time to figure out on my own lol
