I’m trying to figure out where the leak is without pulling the heater out of the cab.
When I flushed the core I didn’t have it under pressure. Just flowing through. Don’t think I could have over pressurized it.
There is no sign of a leak under the heater on my rubber floor mat. I pushed in some paper towel in a hole on the bottom right of the heater box. Comes out clean and dry. I removed the little floor heat grill, shoved my iPhone inside the heater box and it looks clean and dry.
I rigged up two 3/4” hoses and connected to heater inlet and outlet. Connected to my air hose with about 5 psi pressure. No sound of a leaking air.
I changed my hoses and filled the core with clean water and let it sit for an hour. Probably lots of trapped air. No loss of water at lower hose, which are higher than engine height. No air pressure. No different than when I first filled radiator. Engine never ran.
I I did find coolant under the foam flooring under pad. So between the steel floor and floor padding. After drying out the coolant, I left a clean dry paper towel under the floor pad directly under the heater. So far it’s staying dry.
When it was leaking coolant it was dripping pretty consistently, not a drip or two. I’m starting to think that I didn’t get the gear clamps tight enough and coolant was leaking past the hose and just dripping down the inside of the steel floor pan.
Any opinions on the use of gear clamps vs spring clamps?
Thinking about refilling with coolant and checking for leeks without battery box so I have better visibility.
When God gives any man wealth and possessions, and enables him to enjoy them, to accept his lot and be happy in his work�this is a gift of God. He seldom reflects on the days of his life, because God keeps him occupied with gladness of heart. Ecclesiastes 5:19-20
