The wife took the Mustang to pick up a few things at the mall this past Friday while I took the Taurus to officiate a football game out of town. Had been having a problem with something eating the fan belt and causing it to need tightening every now and then. Told her to watch that while she was out. When I went out to take it for a spin Sat morning, I checked to make sure the belt was ok but it wasn't there. Seems that somewhere along the way the fan belt broke and she didn't notice it. She said the temp guage never got over half way and the battery is still strong. Anyway, I removed the pulleys and sanded and painted them before I put the new belt on. After this and adding a little over 1 gallon of water, I started the engine. As it warms up, I start seeing M & M sized bubbles coming up through the radiator. Not a stream or anything, just a bubble here and a bubble there. Could this be bubbles trapped in the block or am I about to replace head gaskets?

Dave,
Sounds like you have some air in the system. Keep a close eye on things, especially your coolant level. Also watch for white milky substances. You don't want them.

We'll run it and see how it goes. There's no water in the oil.

Thanks.

Dave,

Is your belt aligned correctly on those pullies? Belts arent' supposed to get eaten.

It's probably just air in the system. Let it idle until all the air bubbles go away.

That was my first suspect in the deal but they are fine. There were some rusty sections on the crank pulley which may have been the culprit. In any case, I sanded and painted all three pulleys so it should be ok now. Wouldn't have had this problem if I would have done that to begin with.
