Mark coolant, cooling system and such off the list of things im apprehensive to work on.

Chemically flushed my cooling system, new water pump and t stat. Still hate cooling systems though.

Turns out the cruiser is a great car to learn cooling system work on. Hoses are easy to get at, thermostat is 3 easy to get at bolts, water pump is 6 easy to get at bolts. Only trouble was getting the belts loose enough... Until I realized Toyota is awesome and made the tension bolt a straight shot from the wheel well, after that it was easy.

If this doesn’t solve the heat issues it’s fan clutch mod time then new radiator... Again.
