NO COOLANT

I mix one pound of citric acid powder (local baking supply company or E-Bay) then fill the cooling system with that .

DO NOT try to add citric acid to the cooling system filled with water ! .

In the end, I had to junk the radiator, it looked fine but the coolant temps were *slightly* over 82* C and tended to go up to 100*C abd back down again on hills in Summer with the A/C on ~ I installed a Danish NISSIN radiator and it's never once gone above 82* C since no matter how hard I run it and I run it harder than most ever run anything .

Because I'm a Junkyard Junkie and Field Mechanic I have way too much experience with neglected or mis treated cooling systems .
