Low coolant temp.

Got a '95 F-350 C&C. 192 degree thermostat. Getting the engine warm enough to make heat is so far impossible. Even this summer pulling 14,000 pounds in 95+ temps, the engine barely warms up. Now that it's getting cold, it's kind of a problem. We've had a couple of days that the morning temps were below 30 degrees. I let the engine warm for 1/2 an hour, and it was still so cold the ebpv was still cycling. I put a piece of cardboard in front of the radiator, and it helped some. I'm going to put a 205 degree in it today and see if it helps. I have read that some of these engines are just naturally cold. Earlier this year I installed a new NAPA water pump, Ford thermostat, Ford anti-freeze, and a new Hayden fan clutch. The cooling system is super clean with no obstructions. Any tricks here, or is it just the way it is?

Re: Low coolant temp.

Are you sure the heater core isn't plugged?

Re: Low coolant temp.

Everything flushed perfect when I serviced it earlier. I even flushed the heater core separately. There wasn't as much as a spec of dust in the system. I am going to check and make sure the heat selector is working properly.

Re: Low coolant temp.

That would be my next suggestion. The blend door actuator could be malfunctioning or the door may be broken preventing you from getting heat.

Re: Low coolant temp.

I checked the cable at the door, it's working. I couldn't tell if the door was actually working or not. I'll have to dig a little deeper.

Re: Low coolant temp.

It was the blender door not working. Got it closed for the winter. I'll fix it in the spring. Good thing, it's starting to get cold here in Michigan.

Re: Low coolant temp.

Yeah, it's great. I also changed the thermostat again and went to the 205 degree. Coolant temp now comes up off the cold mark.
