Just bought a 89 Bronco 11, drove it about 12 mi no problems, came home and after a few minutes heard a bubbling sound. raised the hood and the water was backfilling the canister. after a few mi the water drained back down. Any suggestions: thermostat, water pump, etc?

I'm going to assume you have a 2.9L... correct?

These engines don't like to be overheated... it will typically crack the heads.

I would proceed with caution while trying to figure it out. There are many things that can cause over heating... ignition timing... coolant level/condition/flow... thermostat... water pump... plugged radiator... etc...

The first thing you should do is google "cooling system glove test". This should tell you if you have a problem with head gaskets/cracked heads. Its common on 2.9L engines and the first thing I would rule out.

Yes 2.9L. Will check out the glove test.
