Where can is the cooling system bleeder valve located?

The 3.1 Engine has a small brass bleeder located in the pipe that runs from the water pump across the top of the valve cover at the front of the engine, as well as sometimes located on the thermostat housing.

On Ford you have to bleed the system of air in the cooling system there are several ways to do it, Here is the easy way withe the vehicle cool to touch open the top radiator hose add the coolant or water through there

Bottom of Radiator, it's a purge valve.

Bottom of Radiator..It's a purge valve.
Like a tire stem

at each wheel there is a bleeder.

On refilling your cooling system with coolant you may have to bleed air from the system via a bleeder valve usually located on or near the thermostat housing. Fill the cooling system and then with the engine running open the bleeder until a solid stream of coolant is emitted for several seconds.

Look for bleeder valves somewhere on the top of the cooling system. If you see any use them to remove trapped air. Start the engine and slowly turn the screw to remove trapped air. If there are no bleeder screws then remove the radiator cap from a cool engine. Make sure the radiator is full. Start the engine and watch for escaping air bubbles. Keep the radiator full at all times. When the engine reaches close to full operating temperature and you see no more air bubbles escaping put the cap back on. You may have to do this one more time if you experience any more trapped air in the system. Just make sure to look closely for bleeder valves. They will look like tire valves with a cap.

Did you replace the thermostat? If not replace it. Is the cooling fan running? If not check the fuse & thermal relay. If it has a bleeder valve it will be located on the highest part of the cooling system. It may not have one. With the engine cold remove the radiator cap. Make sure the radiator is full. Set the heater control to Hot. Start the engine and watch for escaping air bubbles. Keep the radiator full until you see no more air escaping. If it continues to overheat repeat the process.

Did you replace the fan? How about the fan switch?

Here is some stuff to read about this system....please let me know what's up!


This switch is the primary controller of the operation of the radiator fan(s) used for cooling. When the coolant in the system reaches a pre-determined temperature, the fan switch closes and completes a circuit. The fans will be brought on. Generally, the switch communicates with the fan relay, although the later PGM-FI cars send the signal through one of the many solid-state controllers first. Do not assume that the switch is the only component in the radiator fan circuit which controls its operation. There are many other components whose failure may prevent the radiator fan from operating. If the fans are not working when the engine is very warm, check the fuses first.
On all vehicles except 1990-95 Accords and 1992-95 Preludes, the fan switch is located in the bottom of the radiator. On 1990-95 Accords (except V-6) and 1992-95 Preludes, the switch is located in the housing at the rear end of the coolant connecting pipe. This is the pipe running along the outside of the engine, just above the oil filter. The switch the only electrical component in the housing. On the Accord V-6, it threaded into the side of the coolant crossover pipe (not next to the bleed bolt) on the transaxle side of the engine.

According to my data base it has one, but it doesn't give the location. The ones I've seen are located on the thermostat housing or on the engine close to it and they look like a brake bleeder valve.
