1952 8n coolant capacity

Clem Smith · Nov 14, 2009

Does motor have to be warmed first to open thermostat or bottom hose pulled for complete system drain/flush?

Manual says coolant capacity is 12 quarts.

I opened both radiator and block drain petcocks.
Drained and flushed system (didn"t quantify volume drained).
Engine cold.

Added 1 gallon antifreeze and 1 gallon water.
Radiator is full.

Where does the other gallon of fresh water go?

I've never gotton 12 quarts in one of mine. Probably don't get all the old stuff out. A gallon of each is fine as long as it is just over the radiator core.

On a totally empty radiator & block, I can get 11 1/2 quarts of coolant in & it just covers the core. Which is all the coolant that's needed. I'd say you have a water jacket filled w/ rust and/or you didn't get it drained.

If I drain my radiator, and my block, on my '49 8N, and refill it, it takes me right at 2.5 gal. (10 qt) to have it at the level that I normally keep it at.

Clem.......I ALWAYS pre-mix my anti-freeze to 50/50 concentration so enny time I need to add water, there is NO GUESSING as to too-much or too-little concentration. And BTW, you can now buy 50/50 anti-freeze (read increased profit margin) for the chemically challenged shadetree mechanic ......Dell

When I change coolant,I pull bottom hose and run water through rad.If and when it runs clean,I replace hose,fill it up and check every time I run it.---lha

Make sure you test the antifreeze solution in the radiator to insure it is low enough for your area.
