Bubbles in coolant reservoir

Coolant runs through the air compressor to keep it from overheating. If the air compressor head gasket blows it will blow bubbles into the coolant system. It's rare, but it happens.

 

Ok i think we got the air compressor thing covered twice now. Im taking people want an apology for my information screw up so i dont get quoted for a third time ? Sorry about not thinking on that aspect

 

Lol, good info, as always.

 

My comment about air compressor was really about the guy questioning coolant bubbles and his air dryer purging frequently. And that was the post i qouted with responce. That tends to be governor or purge valve

 

Oh yeah, I got it. If his air compressor is suspect, all he has to do is disconnect supply hose. ( I hate to bring up the air compressor again). Like I said good info from your posts, as always.

 

As the one post sort of explained.

If the caps go bad. They won't hold pressure and reduced boiling point occurs. If there's no catch then it overflows to the ground. Loss of coolant.

 

I have the same problem on my Volvo. If the head gasket were to be the problem what could be a possible solution and how much would it approximately cost?

 

Just for info, With an Isx you can get bubbles and have the coolant pushed out if the air compressor is worn. It happened to me and it took for ever to get the shop to replace the compressor. After screwing around with expansion tanks and the cap changing the compressor solved the problem of bubbles and coolant being dumped on the ground..
