Coolant blows out of reserve tank

Would a bad thermostat cause coolant to blow out of reserve tank on my 2001 ford f150 with a 5.4liter engine? I found no bad hose, but it did not heat the cab just prior to this happening.

SOURCE: engine is over heating and blowing air into coolant resivor and boiling coolant

1. Do you have a cooling fan system for your car, if you have , please check it, sometimes due to the wire overheated short problem and fan doesn’t work and cause the engine over heat.

2. If the head gasket leaking, you can check you oil steak see if there is white steam oil bubbling ,if the oil has steam and the radiator has oil mixed with coolant , that means the head gasket leaking.

check the vaccum hoses on the passenger side under hood. I think that there are two hoses but it might be three. they get brittle and leak. but they move a little valve that you can move yourself just to see if heat works then. it is inline with the heater hoses I think. Bear with me though because it has been about 3-4 years ago when I figured this one out. it is definately a vaccum problem. there is also a set of vaccum hoses under passenger side of dash, several colors in it. might want to look there because sometimes kicked by peoples feet but money is on the ones inline with heater core. just move linkage and see if it gets hot air. Hope I helped and didnt confuse.

SOURCE: Heater not blowing warm air. Thermostat has been

Check the water control valve behind the engine close to the firewall. This valve opens and closes to allow hot coolant to enter the heater core. It is usually connected to the heater controls with a cable. When you adjust the heater control for heat, a cable activated lever on the valve should move and allow coolant to move through the valve. The cable from the heater control can come loose from the lever, or the valve itself can become corroded and hard to move.

SOURCE: engine overheating

The coolant flush on radiator doesn't do any good. Since you have changed all the key components and still gotten overheated, then the root cause of the problem is the radiator. It got clogged up in small tubes blocking coolant flow. No matter how good the water pump is working but the radiator got clogged up, coolant is not circulating therefore the heat from the engine can't be dissipated to the radiator. Replace your radiator, don't even think about rebuild it. It has been used for 11 years. Make sure to have the correct coolant/water ratio to keep radiator life for years. Good luck.

Testimonial: "Thanks, it was the radiator afterall. They claim hose was attached too tight; caused it to chip. I think I was taken for a ride by AAMCO & Valvoline."

Does a bad thermostat cause pressure to build and blow back into the reserve tank on a ford 6.0


A stuck thermostart will cause the engine to overheat and coolant will be expelled back into the reserve tank.

Let it ran for 10-15 minutes.

Monitor for air pockets escaping from coolant reserve tank.

Small amount of bubbles is OK at 1-5 minute mark

After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.

If you do not see any in rush of bubbles then your thermostat may be partially stuck or rusted badly inside the thermostat hosing.

Give the thermostat host few gentle taps.

If you see larger bubbles surfacing after 15 minutes then should do a hydrocarbon (HC) dye test to test for potential head gasket leak.

Let engine cold down and top off coolant reserve tank.

Start monitor for coolant lost

A coolant flush is require every 2 years or 24,000 miles.

I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.

Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.

Engine is running hot.


Check your coolant. Is the mixture right for your part of the country (weather wise). Radiator flush. Bad thermostat? Do you have heat when the engine is hot? If not then coolant isn't circulating. Don't overheat your engine however or else the head gasket will blow or worse..if it hasn't already.

Running Hot


You may want to reconsider if the fan is working at it's full potential.It seems when the vehicle is moving the extra air flow compensates for the fan not blowing hard enough.Check for radiator obstructions such as leaves and debris.And check for small leaks.Also there may be an air pocket in the system which can still seem like the system is full.With vehicle cold take off radiator cap and run vehicle.Turn on heat to highest setting (blowing).When vehicle reaches thermostat rated temperature(opened thermostat) you will see coolant go down in radiator.Fill radiator while the engine rpm's are up (have someone hold the throttle to where the rpm's are at about 1800) then put on cap before returning to idle.This should remove the pocket if there is one

Overheating,reserve coolant tank boiling I have a 2000 Ford Taurus with the similar problem. I had my water pump replaced then this started.


Ford 2000 Taurus

To solve the problem you have the things to do in this order;

) When the engine is cold top off the radiator with fluid. (When the pump was replaced the fluid should have been also)
) Make sure the radiator fluid has anti-freeze in it. This is also anti boil also !
) Add fluid to the overflow reservoir.
) Make sure the drive belt was replaced on the water pump.
) With the engine running, you can add fluid to the radiator for the first minute or so. You want to get air pockets out.
) Replace radiator cap.
) Let car warm up. When it's hot you should get the radiator fan coming on.
) When it get hotter the air-conditioning fan may come on.
) If the fan does not come on, the heat sensor is probably bad.
) If all fans come on, and it overheats, you may have a bad thermostat. Trace the upper radiator hose to where it connects to the engine. That's where it located.

Do not operate the engine when it overheats, You will damage the head gaskets and cause radiator fluid to leak into the cylinders.
If you smell radiator fluid in the exhaust fumes, it may already be leaking.

Chevy S10 overheated, now heat doesn't work, leaking coolant


When an engine is overheating and then the temp drops on the guage, it's usually a sign that the coolant is not touching the temp sensor. There's no coolant in the engine. Putting water in the overflow tank won't solve this. Take the radiator cap off after the engine cools and put coolant in the radiator. you might have to crank the engine and do this several times, as the engine can develop air pockets that won't allow the coolant to travel inside the engine. If you don't see any leaks, and it still uses coolant, you've probably got a blown head gasket. Check for water on the plugs, check cylinder compression. If it slowly uses coolant, try putting a large box of pepper in the radiator or some of that radiator seal copper flakes.
