Cooling system problem
Hi
I've changed my coolant on my MX5 and I don't think my water pump (or thermostat) is working correctly even though the temp gauge is
normal....
When you run the car without the rad cap on, and it's to temperature what should you see in terms of flow....should the water really be churning
up or is it a very slow flow ?
My top hose is red hot but definitely isn't full, in fact I'd say it is virtually empty and when you squeeze it, it doesn't seem to
alter the level or flow in the rad (with engine on and rad cap off).
Be grateful for any advice
thanks
Paul

Sounds like an air lock in the coolant. Try removing rad cap when cool and make sure coolant runs out. Loosen other hoses and check for same. Good
luck.
