My heat is not hot
 

Hello all! So my Volkswagen diesel pumps out 115* heat from the vents, verified by many with thermometers. So perhaps I'm a bit spoiled by the heat output of my VW... but the heat on my OBS I can seriously have full blast and even after the truck is up to temp (somewhere between the O and R in "NORMAL") I wont even be considered "hot" after a road trip.

I'm thinking the radiator and heater core may need a good flushing, but is there something else that frequents these trucks?

what thermostat does it have in it? i ask this knowing you have no idea. its made for a 203

Not a clue... how can I tell?

got me. i guess they might say on them. i'd have to go look at mine but the 203's are supposed to help a lot so i'm guessing you don't have a 203 BUT it wouldn't hurt to do some maintenance on the truck of course

oh and thermostat could be stuck open

plugged core, low on fluid?

Why would the truck get up to temp then if the t stat was stuck open?

Fluid level is fine. I'm def wondering if it's a plugged core though..

Thats my guess, you can flush it out with your garden hose

i forgot about that detail. and is it dead in the middle? a little high? a little low?

Ya thats what I was figuring to do. Too bad it's 15 damn degrees here lately. Ugg.

No it's def not dead in the middle... it's on the OR portion of NORMAL, if you can picture that?

I would guess you have a T-stat issue, try that first... Do you add the Anti corrosion additive to your truck ever?

Go down to Ford and get the FACTORY 195* stat and install it, do not buy into the hype for the 203* stat...

Might look at flushing the system as well, and adding a coolant filter. You would be surprised how much crap a coolant filter will pick up!
