Hi all,
I've a quick question about the cooling system on my MkII Spit (although I
think it pretty similar on all our cars). The expansion tank is there to
accomodate excess coolant when the car is warm. Once the operating pressure is
reached then the radiator cap allows coolant and hence excess pressure to be
routed to the expansion tank. My question is what happens when the coolant
cools and contracts? The radiator cap must surely be closed isolating the
expansion tank from the rest of the system. I can't quite get my head around
how the excess coolant dissipated when hot can get back to refill the system
when cold.
I'm probably just missing something really obvious!
Cheers,
David
