Have a compression test done as that will most likely be a blown head gasket or cracked head allowing combustion pressure into the cooling system. A quick check is to remove the radiator cap and fill right to the top . Run the engine and if you see small bubbles in the water or it tends to belch out then it will be the gasket of cracked.

SOURCE: my subaru 1996 250t non turbo over heats after

the most common problem with subaru engines is the exaust gas escaping the cylinder into the coolant through microscopic cracks in the gasket...

the tell tale sign is to check the coolant reserve tank when the car is hot, if it has foamy bubbles in the plastic reserve tank ( do not open the radiator! ) then thats a sure sign of gas escaping the coolant...

hot gas in the coolant reduces the cooling effect obviously, and the long term effect is bearing wear which would require an engine rebuild.

the head gaskets are on the sides of the engine, so a gasket change requires an engine removal from car-

$1000 fix ( few hundred for a nice gasket, and a few hours labour )

alot of mechanics don't believe it and start replacing hoses, sensors engine parts etc

don't go down this route, it WILL COST -

check for gases in the coolant

SOURCE: hi there my subaru station

Definitely at least try a thermostat.Seeing how you did the pump already,if it still happens after a thermostat,this is going to be an issue.Good luck! Greg How quick does it overheat?If it's pretty quick thermostat.If it's gradual and you can go like 40 miles before it overheats it could be a loose belt.

Losing coolant through overflow car not overheating2004 vz 3.6 motor

Overflow of what? You could be losing coolant through radiator cap, which could seem like a radiator overflow and problem might be a clog on the hose from rad to expansion tank.

If you are losing coolant due to overflow of expansion tank, any chance you added too much? Always fill to recommended level indicated in dipstick.

With cars it's always worth noting symptoms, how and when they happen. If you're losing coolant for any reason other than adding too much to begin with, it's not a matter of 'if', it's a matter of 'when' the car is going to overheat and cause more problems/cost more, early diagnosis matters.

The overflow need to be filled with water?

Yes, it is important to include the overflow tank or bottle as integral with the radiator and coolant system as a whole. They all intermix. Actually, the level in the overflow tank is a true measure of the correct amount to keep your coolant at. There are two marks on the overflow: full hot and full cold. The coolant system on all modern cars is a sealed system and therefore should never require adding, save a very small amount through evaporation within the overflow tank- the only part that is open to atmosphere.

So once you get all the air out of the system that is possible, both in the engine and in the radiator, you have a full level everywhere, including the overflow tank where it should always remain somewhere between the full hot and full cold marks.

You are right that the overflow collects the heated radiator coolant. But it is due to the expansive properties of coolant-or water- that it expands when heated, (but not boiling-that is very bad news of a different sort). Your radiator cap is designed to open at a specific pressure, just enough to allow coolant to flow into the overflow. As the engine and coolant cools, it contracts, the level drops in the radiator, and a natural vacuum there will siphon the overflow tank back into the radiator until it is full again. That is why you have the full hot and full cold marks.
I will shut off the lecture now. I hope you have liked my answer. If not, I give you permission to kill me now- if I may so jest.

I have coolant coming out from the over flow tank hose when engine is hot is that normal

Not normal no, the overflow tank is there to apply coolant when the engine is cooling down and everything is contracting and to accept coolant when everything warms up and expands. If there is coolant leaking ensure that the coolant is at the correct level when the engine is cold. If it still overflows it could be the radiator cap not holding the pressure of the cooling system and letting too much into the overflow container? :)

Not pulling coolant from overflow jug

Pressure testing just tests that the radiator cap resists a certain amount of positive pressure. I assume you are saying that it is not drawing back from the overflow when the engine cools down. It is likely that the coolant is being blocked right inside the overflow jug by some dirt or debris. Remove the overflow jug and clean it out - and clean the overflow hose too, in case it is obstructed.

Need to find the source of the excessive amounts of coolant leaking from the front-passenger side of the radiator/fan area. I found a tube that is connected on one end but not the other that I am currently...

It's probably the radiator overflow tank hose. It is supposed to be connected the the coolant overflow tank and also the other end at the radiator, next to the pressure cap. It allows excess coolant to escape the radiator if necessary and also to **** in coolant if needed.

Where do u put the water in on a colt? Can't find it?

A tank used for storing excess coolant; connected to the cooling system with a small-diameter overflow hose.

The coolant reservoir is the bottle,under the hood, that holds the radiator fluid. it is also known as a overflow bottle. When the car gets hot,the overflow bottle, releases steam to relive the pressure in the radiator. excess coolant is also stored here.


I hope this helps, Mike from fixya.

If everything is working correctly; thermostat, heater core, water pump, head gaskets, etc. Then that leaves the radiator cap, the overflow hose or the overflow tank as being the problem.

As the engine heats up the coolant expands flowing into the overflow tank. As the engine cools the coolant is drawn back into the engine from the overflow tank. but this depends on the vacuum created by the cooling liquid. the radiator cap has a "valve" that lets pressure out and vacuum in. If it fails then you may not achieve a good vacuum. The hose that connects to the over flow tank must be non leaking as well; if it leaked then coolant would not be drawn back into the engine, only air would be sucked in. And lastly the coolant has to be drawn from the bottom of the overflow tank. again we dont want to be sucking air.

Some engines require a vent screw to be opened when bleeding the air out of the engine.

add coolant to the overflow tank. when needed, the radiator will **** coolant from the overflow into the radiator. coolant is added to the overflow tank due to this being a closed - pressurized system
