doesnt get hot

[swamprat]

Mine ranger didnt get hot one winter. I checked the coolant level and it was low. Filled it up and found the leak and had heat all winter.

my brothers heater core was plugged with crap from the GM coolant that general motors uses, its like a clay when mixed with the green stuff he said.
he took his air hose from a compresser and blew it out, reconnected the hoses added a little fluid and has heat now.

alright guys i havent had time to look at the heater but today i am going to..i thought my gauge was working but it isn't..i think its weird no movement in gauge and a heater that doesnt work..if my t stat was bad i would be overheating but im not. any ideas? think i should just replace the t stat and see what happens?

FIXED: t stat was stuck open. thanks guys.

If the T-stat was stuck closed it would overheat, stuck open it does just what you had.

Glad you got it fixed!

If you have your heater on it could be your heater control valve

 

[WTCBST]

im having the same problem with my 88 ranger,,, it blows just fine, xcept when the heat is on its not hot, or warm, its just not cold, which really bites a big one.

but what i dont understand is that i can drive the 90 miles to kansas city drive around town and drive back, and the heat be only just a little bit warmer... can sum1 tell me whats wrong?
