It is, to be honest, most likely that the head gasket is shot if you can see bubbles and she's drinking coolant.

Water comes out of the over flow bottle(i checked the cap)


make sure you dont over fill the radiator bottle past max, something else to try is run the system with out the cap on for a few minutes at idle to expel any air pockets in your cooling system.

My coolant expansion tank overflows after 20 minutes of running the engine


you either have a blown head gasket or cracked head both reasons will put compression gas into coolant system since air gets hotter faster than coolant any air in system will cause very fast over heating and push coolant out. the ford 3.0 is has a record of this problem the fix is not cheap and if you do it your self or have a shop do it both heads should be done and the t stat also replacing water pump would be wise

Cooling system problem


well it might overheat because air got into system, replace the thermostant and then fill system, run van keepin an eye on the temp, it will start to run hot because coolant has not filled the motor just the radiator, when it starts running hot shut it down, wait 3 minutes and start, now this is done with cap off,after restart coolant should get sucked in get filling radiator as needed,may get messy but got to bleed cooling system. hope thius helps.

How to replace thermostate on a 1987 trans am 350cui were is it located ?


Follow the top radiator hose back to the block.There you will see a little thing with two bolts or nuts on either side.Looks just like a igloo.Under this is where the thermostste is.Try to drain out some of the antifreeze.Drain valve on bottom side of radiator.Remove the hose clamp and hose from the thermostate housing,then the two bolts or nuts.Push a paper towl down into the opening so nothing gets in. Start scaping the old gasket off both surfaces.Before you install the new thermostat place it in a pan of water then heat it on the stove until it opens.I always make sure that the work.Now remove the paper towl and dry all surfaces.You can use a gasket or just a small film of silicon on the housing and intake manifold.Reinstall,reconnect the hose,refill the radiator.Run with cap off until you see that there is no more air and that the coolant is flowing.The coolant will rise as the engine heats up so don't fill to high at first.

How to replace thermostat 93 VOYAGER to keep radiator cooler


The thermostate will be found under the upper radiator hose where it meets the engine. With the engine cool disconnect your battery ground (safety sakes) Down low on the radiator you will find a petcock (valve) place a bucket under this and open draining out @ 1 gallon or so of fluid. Remove the upper hose and the the thermstat housing (2-bolts) under it you'll see the thermostate, remove and clean all surface of old gasket. Install new thermostat2.gif and new gasket, reassemble, add fluid and place battery ground back. Run the engine for a moment and watch the fluid level after one minute or so add more fluid (if needed) and install cap. Get engine to temperature and watch for leaks. Next two days or so I'd monitor the fluid level in the over-flow and add as needed. Again watch for any leaks. The job itself should only take you an hour or less.
Please let me know if this assited you.
Thanks,
Tom

Ok, Take the overflow hose out of the overflow tank and opput the end in a glass or jar of water. Start the motor and watch gfor bubbles coming out of the hose in the water.. Little tiny smokey white bubbles mean you have a combustion leak into your cooling system. Possible head gasket seapage.good luck

2001 DTS Deville Overheating. Cant find leak. Checked waterpump and looks Ok. Only seen coolent at overflow when overheating. Cooling fans are running ok. Will try to find problem by starting by changing...


if you have a blown head gasket you would have a miss
the waterpump can look good and still be bad
after you replace the thermostate fill the radiator and leave the cap off start the car let it get too operating temp and check for flow if you have good flow shut the car off and and put a pressure terter on the raidator this will tell of and leaks

How to change out thermostat in 1991 buck centry 3300


your thermostate is probably on the block sideways in whitch case you need to remove the air filter outr of your way and loosen the clamp on the thermostate housing. from there take out the 3 bolts holding the thermostat housing in place and remove it. Caution water/antifreeze will come out. take the thermostate out watching where the gasket has been placed and install the new one after cleaning the suface of the old gasket. sometimes it is good to use indian head gasket sealer. there will be 2 bolts on top and 1 bolt on the bottom under the housing. install the new thermostate tightn the hose replace your filter and fill the over flow resivor only to the point on COLD MAX. take the cap off the radiator start the car wait for the thermostate to open and fill the raditor the rest the way up. if it starts to boil over just shut the car off and let it cool than add more water *** needed...
