flushing a cooling system is the same method as any other motor
do it without the thermostat fitted
or water pump opening
sacrifice an old radiator hose to adapt a garden hose fitting
for radiator flush
air in system fix
your thermostat housing has no air bleed valve
no top radiator cap
old school way
heater on full
run motor till thermostats fully open
burp radiator hoses
wait till water is running up into over flow bottle without bubble
replace cap
turn off heater
correct level in over flow bottle
why still over heating
you fitted everything i would have ... yet still overheat
possibles
leaking inlet manifold gaskets
hose clamps loose
cooling fans spinning too slow
thermostatic fan switch faulty
aluminum radiator is a big one
air ..fins bent or some water channels blocked
or possible head gasket leak
