No heat?

[Joe0816]

I have no heat coming to the cab except for when I'm driving. And its snowing here, and its hard to keep the windshield de frosted. Any ideas?

Have you changed your thermostat... Might be stuck open

[poormanscat]

make sure the surge tank is full to the top mark. on my S.I.L. truck, I actually removed a hose and stuck a funnel in it and filled it that way. The engien had plenty of coolant, but the heater hoses were air locked.

[jesilvas]

Both good ideas.
If neither, possibly the pump

I made my Samsung SGH-I997 send this.

What is a surge tank

[madpogue]

It's the coolant reservoir. What year is your truck?

[Joe0816]

1997 is the year, and just replaced the thermostat yesterday, and the only thing I noticed was the engine seems to warm up slightly faster. May be my imagination though, lol

A bad pressure cap can be the cause also

[Joe0816]

If your talking about the coolant cap, no because i have good pressure.

Any other ideas before I throw Ford the keys and tell them to figure it out?
