I've yet to be able to determine if it is a cooling system inadequacy or engine producing too much heat, but I've replaced the thermostat, water pump, rad cap, and rad. I'm pretty sure that the heater core loop is free flowing, I get heat in the cab.
I've checked with IR gun and it is truly overheating, or at least, borderline. I've also gotten boilovers, but am not currently.
I think my main problem right now is there is air in the cooling system and I can't figure out how to bleed it. Can someone provide instructions? I've tried cranking it with the rad cap off and running at 2500 rpm, but eventually it just sprays coolant out of the funnel violently.
This is the rad cap I bought, I'm concerned it is incorrect because the level in the overflow tank doesn't move when heating or cooling down.
