As long as the coolant goes back down when cool things are okay. Make
sure the pressure cap is doing its job. Have tested or simply replace
it. They fail often.

Subject: Colant expantion

Hi List,

I recently changed the coolant in my 1.9 wbx to an orange dex-cool fluid
(50/50 mix). I have bleed all of the air out of the system and the main
coolant reservoir is now staying full.

I have filled the expansion tank to the max line when the motor is cold.
After the van has been run up to temperature and shut off the level in
the expansion tank will rise 1/2 way up the cap, when everything cools
off the level will drop back to the max line. Is this normal or do I
have a problem? This van had green coolant in it before and I never
noticed the level in the expansion tank getting so high, but I never
looked. In the past I always made sure the fluid was up to the max line
when cold. Does the orange fluid have a different expansion factor?

Thanks,

George
