I have a 1998 Ford Explorer with a new a/c condenser and new water pump. My newest problem is that the a/c will start off blowing cold air, then I will hear a noise sounding like a vacuum valve closing and hot air immediately comes out. It seems to happen when I slow down or come to a complete stop. Could this be a vacuum line? If so please explain. Thank you!

It sounds like there may be a serious issue with your 2000 Ford Explorer V6. The heater blowing cold air and overheating, along with water coming out of the bottom of the engine when water is added to the radiator, are all signs of a potential engine problem. It's recommended to have a professional mechanic inspect the vehicle to diagnose and repair the issue, as attempting to fix it yourself without proper knowledge and experience may result in further damage to the vehicle.
I just replaced the thermostat assembly on my 2005 ford explorer since they are made of plastic they crack and leak and you can hardly see it because the water retains in the middle of the block hope this help.
make sure your heater core is in good condition this could be done with a compression test, if that is fine i would make sure the climate control switch is working proper and not shorting between cold and hot
My first thought is to check the fuel pressure. You could have a faulty pump relay or a bad valve in the pump. The one way valve in the pump prevents pressure from leaking back into the tank when the engine is off.
The most common cause is a bad blend door actuator which controls air flow throughout the cabin. When air flow only flows from 1 section (either floor, vent, or defrost) it's an indication that the blend door actuator is either stuck or broken.
mmm i had the same problem with my 1998 4.0L Ford Explorer probably a leaking condenser, sounds like you have a problem with your AC system, i suggest taking it to a ford servicing centre.
Maybe Not Thermostat, could Be Blown Head Gasket Or Cracked Head. Working On 98 Explorer Right Now. Is It Blowing Excessive Steam From Exhaust, Water In Oil Or Oil In Water
