It should self bleed but I find it takes 2-3 runs to fully bleed. Before it's bled the temp gauge will venture to 100*C when it's not under load and there'll be gurgling sounds from the heater core. Go home, wait for it to cool, top off reservoir, lather, rinse, repeat. After the second or third topping the gurgling stops and the temp gauge doesn't go to 100*C unless you really load the engine.
To speed things along, I remove the 3-pin temp switch where the upper radiator hose attaches to the engine so it bleeds as I'm filling. Fill slowly so it doesn't gush out the hole. Sixto 87 300D |
