I put at GT20 turbo on my 1985 3B BJ70 and I’ve been having overheating issues since I did that. If I drive over 70Km/hr, or up a hill for more than 30-45 seconds (rpm’s over 2000) the temp gauge shoots up to the red and coolant spews out the overflow. I’ve burped it countless times due to the high temps shooting out so much coolant, replaced the thermostat, checked the water pump is working, installed an intercooler, replaced the clutch fan with a 3000 cfm electric fan, and had the radiator rebuilt. There isn’t any coolant in the oil or oil in the coolant. I’m out of ideas. Is there anything I’m missing?
