I have coolant dripping below the glove box. Every thing looks fine from the engine compartment. Can you help me? F250 '93 7.3diesel. Thanks

 

heater core?

 

That would be my guess also... Heater Core

 

Well this is my first heater core problem. Is this a reasonable DIYS projet? Do you have any tips or guidance? Thanks

 

98% leaking Heater core. 2% Hose issues.

HOSE problem: Could be loose/cracked hose going in/out of heater core if hose/core connection point is inside firewall and not accessable from engine compartment. I have seen this happen 2 times.

HEATER CORE problem: When you turn on the windshield defroster - probably has a sweet smell and clouds up the glass even worse than before. When it gets really bad your front passenger side floorboard will be soaked. You will probably have a slimy film of coolant on the inside of the windshield now. I have seen this happen many times.

I have never replaced one on that specific model before. Save tons of $$$ doing it yourself with a Haynes Manual for $20 & a new heater core for under $30.

Sometimes have to release the pressure in the A/C system (like in the early '80s Ford cars) which will cost more money to fill it again. If you must do this, go to a shop and have them perform an 'E-VAC' (a/c system refrigerant evacuation procedure). They will hook the machine to your a/c system and basically suck out all your freon. Then after your work is complete go to the same shop to fill it - they should give you a discount (if the shop originally sucked out 2.5 lbs and then gave you 3 lbs back, because your system was a little low in the first place, you should only be charged for the 0.5 lbs of freon).

 

you might have to take out the entire dash. if so, its do-able, but long n tedious
