    Thanks for your interest in this question . I found out from the former owner that there are 3 bleeder ports on this motor one by the thermostat, one on the front corner of the motor, and one near the return hose.

Proper proceedure of coolant is if the radiator requires half water and half coolant or full coolant to fill engine if coolant low mix a bottle of coolant half a bottle and then add water to the other half of container for proper adding back to radiator
ok heres how you properly fill a radiator and fill can in engine compartment
start vehicle when cool
poor in proper fluid till comes up to top
now wait till engine warms up and thermo kicks in this will drop the fluid after about 5 minutes to warm
then fill back till top off not over flow
the engine will pull fluid where needed

dont be scared by head gasket the indicator of a blown head gasket is your oil will look like chocolate milk when you pull the dip stick or do an oil change
if head gasket blown dont drive you will then crack the block tow truck to tech or as do it yourselfer doing the work

Is there a fuse that runs the radiator fan in 1997 buick lasabre

there is a fuse aswell as a sensor switch in the radiator itself which when reaches certain temp activates fan to cool radiator, if radiator isnt getting all that hot or not at all there is a thermostat built into cooling system, generally to side above gearbox or to the front of engine, this could be stuck closed which will prevent water circulating, you can identify this part by looking for a dome shaped plastic or metal piece bolted to engine (generally two, one either side, and it will have an electrical sensor located in it or beside it, drain coolant, remove domed cover and there you will find thermostat, purchase replacement and refit making sure to clean all joining surfaces and use or apply proper gasket or liquid gasket to seal joint, filling cooling system is bit mor tricky, for this just google car make model with coolant filling procedure, dont forget to add anti freeze when refilling, this also acts as a summer coolant.

I replaced the thermostat,the car still over heats and the heater still does'nt blow heat. the sticker under the hood says there is a special way to add coolant is there? I dont have a services...

It's probably air bound. In my 51 years of working on cars I've never heard of a special way to add coolant.
I just put some in the radiator or the container, start the engine, wait for the thermostat to open,then fill it, leave the cap off so it won't get air bound while it's running.
If there is a bleeder valve on top of the thermostat housing, open that until there is a steady stream of coolant coming out, then close it and refill system.
If it still over heats, you might have a clogged radiator.

How to change coolant on 2000 gmc 1500

Each vehicle's radiator has a drain pet-**** on the bottom of the radiator. Generally it is on the drivers side of the radiator. Open this pet-****, drain the old coolant into a pan and dispose of properly. Close the pet-**** and refill the radiator with a 50/50 mix or antifreeze and water. The attached link explains the entire procedure.

Please rate my solution. Thanks!

Take this to a knowledgeable technician or garage for a flush and fill.Air pockets can develop in the system and may cause the car to overheat.If you have not done this before do not attempt it.

How do you replace the thermostat

Partially drain coolant level to below thermostat level if nessasary. Follow top radiator hose over to engine. Where the top radiator hose stops at engine is where the thermostat is. Hose is connected to a pipe ( called a thermostat housing) that bolts to the engine. Remove components if they are in the way of accessing the two bolts or nuts that hold down the thermostat housing. Remove thermostat housing. Thermostat is under the housing. Replace thermostat and paper gasket or rubber o-ring. Be sure to clean surfaces of area where the gasket is mounted. Reinstall thermostat housing but do not over tighten the housing bolts or nuts. Reinstrall components removed and refill coolant to proper level. Do not forget to close radiator drain. Do not put radiator cap on at this time. Start engine and let run for a few minutes to get air out of system. Stop engine and refill coolant if needed. Install radiator cap and check coolant resevoir and fill to proper level if needed. Hope this helps.

A red arrow point down in a dashboard

The figure is supposed to be a radiator with low coolant level. It comes on when coolant level is low and when there is air in the system, refill system as needed, if the light does not go away in a couple of days, bleed the system. To bleed the cooling system follow the procedure highlighted on your owner' manual.

99 Chrysler 300M. As there is no visible radiator cap, when I drain the cooling system does it refill through the reservoir?

The reservoir is the traditional top tank of your radiator.

The answer to your question is yes.

Where is the thermostat cant find a repair manual for 97 Sportage ..need to know where the thermostat is located

just follow the top radiator hose toward the engine. that metal housing that the radiator hose hooks up to has the thermistat under it take off the two bolts and change out thermistat.refill with coolant then run for about a half hour to warm up enough to open thermistat, then top off with coolant at the radiator cap.leave cap loose during this operation so that no pressure will build up in radiator.if unsure squeeze upper rad. hose it should easilly compress if stiff pressure has built up so dont open the cap. let cool then top up coolant

Forester 04 Top radiator hose dilemma !

You really won't lose that much coolant in just changing the upper hose.
But, crawl underneath the front of the car, and somewhere along the bottom left or right hand corner of the radiator, you'll find a valve of some type. Either rotate/turn the valve, or pull and turn, to open. Be sure to have a clean bucket ready and under the drain while doing this, to catch the drained fluid.

Then remove the radiator cap to allow air in the top of the radiator and speed the flow. Drain only to a point in the radiator that is below the lowest point of the top radiator hose, probably the engine end. Close the drain.
Remove/replace the radiator hose. Pour coolant from bucket back into the radiator where the cap was removed. If it does not all go, then save.
Start engine and allow to warm up. As soon as you see the level drop (meaning the thermostat has opened) add more coolant, and continue doing so until no more coolant can be added. Replace the cap. Monitor the coolant reservoir and add coolant as needed to the appropriate fill line.
Do not store excess coolant where pets/animals could consume as it lethal such creatures.
