The coolant is always disappearing from the header tank in my AU3 Sedan (6 cylinder). I have replaced all of the hoses, new thermostat, new three core radiator, replaced the Welch plugs under the exhaust manifold, which I am lead to believe is the coolant side of the motor, new coolant (Nulon). When I done all of this work, I also installed a transmission cooler to keep the coolant and ATF fluid in separate systems.

I am at my wits end as to what is causing this problem, and I would really like to have it fix, once and for all.

The car doesn’t go into the red on the temperature gauge on the dash.

Please any help/information would be greatly appreciated.

Regards,

Holocaust
Peter

Have you checked your oil to see if the coolant is mixing in there? It may well be a head gasket.

How much are you losing?

how quick does it disapear???

When you fill it up with fluid, are there any bubble's?????

Could be that it's the Head Gasket/ Head Cracked, and it's cracked around the exhaust, and as that part is hot, it evaporates.

Damn it, I forgot to mention the cap has been changed int he past, the rubber appears to be in good condition right now.

If it is a blown head gasket, what sort of dollars would I be looking at??

Anywhere from a few hundred (DIY) to a couple of thousand in a workshop. Also depends if any repairs are required on the head. How many KM are on it?

I think the next logical step would be to get a compression test and see what the results are.
