My 1998 Ford Ranger’s (4 cylinder) heater is stuck on high heat. Every now and then I will be traveling down the road and notice that the heater is not putting out any heat. Then I look at the temperature gauge and it will be dropping. It will go all the way to cold. I know of things that will make a motor over heat, but not cool down. Anyone know what is going on?

A stuck thermostat won't cool a engine that quick... I'd go with Ford man with a low level of water, or you have a air bubble from improper cooling system work.... If you don't burp the air from the system it will cause weird issues like you describe.
But usually it will overheat then go back normal than what you describe

Your either low on water in the radiator or you have a stuck thermistat. When the engine is cool, open the radiator cap and check the water level (only do this with the engine cool!). Top off the water until full and then fill up the plastic reservoir too. Run the car after until hot and then see if your heater works. If you are still having the problem you probably have a stuck thermostat and that will have to be replaced.

hi before everything, seeing as how that's a diesel engine and not a petroleum engine, there'll be no carbs or distributors to envision out. If i'm no longer flawed, the later Endura DE engines in Ford Escorts are no longer intercooled, and as a result we are able to rule out the intercooler pipe coming adrift, yet there's a hollow interior the rapid pipework, or loose rapid pipework. I additionally think of they have a MAF sensor with the help of the air filter out housing interior the inlet trunking. Disconnect the wiring plug from the MAF and spot if it makes any enormous difference. yet another concern those engines have is the pump timing solenoid on the gas pump, and the develop pill, additionally on the gas pump. different tests may well be the EGR valve sticking open and the coolant sensor, and consistent with risk even failed injectors. If there is any white smoke from the exhaust then you definately could discover the the gas primer diaphragm has split interior the housing, it particularly is yet another straight forward concern with those engines, or consistent with risk an straight forward gas air leak. Is there any black or white smoke from the exhaust? Cheers Geordie

Most common reason is a stuck thermostat. It's stuck open, so the water never gets very hot, especially while driving down the road. Replace the thermostat.

You might be low on coolant. When this happens, there isn't enough to circulate into the heater core and it goes cold, also the temp sensor isn't seeing any cooant and will actually go colder, even though the engine is getting hotter.
