On a cold engine remove the rad cap and loosen any bleeder screws if any.When the upper hose starts getting hot the level will probably go down.Make sure your heater is on as well.Add fluid as needed.Tighten up the bleeders if not already done.
remove front bumper it comes out the bottom. of course detach anything else holding it in. bleed the system upon refilling.
Have the vehicle running when refilling the radiator, or top off radiator after engine warms up, and thermostat opens (temperature gauge will drop). Some engines have a cooling system bleeder you can crack open and fill the radiator until coolant comes out of the bleeder. The bleeder is generally located at the highest point of the cooling system on the engine.
No, if there are valves so the radiator can be isolated only the radiator needs to be drained along with the location it is being moved to. If no valves are present you would only need to drain to a point below the radiator in question, so it is empty but the rest of the system can stay full. When refilling, unless it is steam the whole system will need to be bled of air.
Air in the system. Bleed the cooling system and remove any trapped air pockets.
IF IT WAS NOT OVERHEATING BEFORE THE HOSE WAS REPLACED -- MORE THAN LIKELY YOU HAVE AIR POCKETS TRAPPED IN YOUR COOLING SYSTEM
yes you do cuz if you dont you will not get the air pockets out and then your radiator fluid could be to low no
before refilling your fuel tanks
The radiator is part if the cooling system.
I've experienced this and had it boil down to air pockets in the cooling system. My fix was to run the engine for 10-15 seconds, then squeeze the top radiator hose with the radiator cap off. This would cause a change in the level in the reservoir, and eventually work the air bubble out of where ever it was hiding. With the radiator cap off, you will eventually see a stream of fluid coming out just below the cap as you squeeze the top radiator hose.
before refilling your fuel tanks
Have you done a rebuild? Is this why your trying to purge the cooling system? Typically you will need to run the vehicle till the temp gauges reads near overheating, then allow the vehicle to nearly cool and remove the radiator cap. This allows air pockets to be pushed through the system. You can also run it to normal operating temperature and slowly crack the radiator cap allowing the system to expell excess pressure.
AnswerShould be located at the engine end of the upper radiator hoseOn the 2.7 motor the thermostat is located at the engine side of the lower radiator hose. It's a difficult job to change, the alternator a/c compressor and bracket need to be removed, at least unbolted and moved aside, and they have to be accessed from the passenger side inner fender as well as from under the hood. If you also remove the dipstick be sure to cover the hole so anti freeze can't get into the oilpan. I just unbolted the dipstick and moved it away without pulling it out to avoid that. Upon finishing I also had a problem with air pockets in the system when refilling with anti-freeze, the system must be bled well.
