My van is overheating…
I’ve replaced:The radiator &
the cap/ Fan assembly /water pump /hoses/thermostat. The dealer says there’s nothing wrong. But they can’t tell me why it’s overheating.
I asked the dealer & 2 other mechanics to check for a head gasket leak or cracked head - they all say there is no leak or crack.

I’ve discovered over the past few weeks that the coolant does not flow back into the radiator when it’s needed. It does flow out into the reservoir - but not back.

Any suggestions?
