Hi! Check to see if there's a water leak in the system.For the overflow not to mix with the radiator it has to be loosing vacuum,This will cause the overflow water to remain in the overflow reservoir.

Have you tried removing rad cap when cool & adding coolant while engine running & heater on. let it run through 2 or 3 cycles of rad fan coming on & off before you put cap back on. As far as coolnt return not working properly, possible bad rad cap, or kink in return hose, have a look if that is the problem.

Head gasket or IM gasket? overheating, think there's antifreeze on spark plug threads. drained flushed bled system. new thermostat rad cap. still overheating.


Somebody been using tap water in their radiator? The vehicle is old enough to have a lot of accumulated rust and crud in the Radiator which, depending on relative water quality and location of water pump could over pressure the system and have it squirting into overflow. If the threads of the plug have antifreeze on them it's coming from the OUTSIDE not the inside.

2002 Oldsmobile Intrigue- Radiator Flush


you may need to replace the thermostat or the water pump to solve the overheating issue.
The leak in the overflow was NOT the cause of over heating.
You do have a radiator cap. It is the one on top of the overflow.

The radiator drain petcock is on the bottom of the radiator near one of the corner edges.
(Some face engine, others face the grille)
If for some reason you still can not find it, you can always pull the lower radiator hose (make sure water/engine is cold)

once you flush/fill the system, use a 50/50 mix of water and the proper antifreeze. (older cars use green, newer use orange)

If you are unsure, just ask the guys at the auto parts place which one you need and note that they sell an orange color that can be safely used in old and new cars and it can also be mixed with any color of fluid.

After you have the system filled, start the engine and remove the fill cap.... let it run and watch for air to rise out from the opening. (Some coolant/water may overflow, but you need to watch for any air bubbles coming out)

Once you don't see any air trying to escape, put the cap on tight and you should be good to go,

Another cause for overheating is air trapped in the system.

I hope this helps.

Why is my oil pressure running high after my jeep overheated?


One possibility is that water has mixed with the oil forming a thick chocolate milk like mix that when pumped through the system increases the pressure

My 1999 Chevy Malibu is losing the coolant though the overflow hose by the resevior I've had my head gaskets replaced there is no overheating no water oil mix, but my radiator fans arent working I


Sounds like you need to disconnect the Radiators' electric fans and have them tested. You absolutely must have them working, or your car will overheat. Check to see if the Temperature guage is working.

You need to go to a good autoparts store and have them test the fans and charge and test your battery. You may need some sensors to activate the Radiator fans, but you could be running the battery down with shorted cooling fans.

There are also Relays which work with the Radiator fans. The overflow will stabilize once the water gets into where it belongs. Make sure your Thermostat is not clogged with the sealer.

Overheating


there is a coolant cap on the overflow bottle check it for seal
i'd just replace it
also if you put the new thermostat in backward the overheating would be significant

Heat dosent work


when you mean cranks do you mean the blower runs or heat comes out for 5 sec,if its the latter than the heatcore is plugged or water pump is weak if its the water pump then increasing the rpm's the heat will warm up,look into the overflow tank or radiator and if anything looks like pudding than someone has mixed orange and green antifreeze and plugged up the cooling system

The overflow tank ( sorta off white see through bottle with green stuff in it) has a hose attached to the bottom of it that should feed itself into the radiator ( usually right where the radiator cap is ). Make sure its connected .
