Info needed: Morris C8 radiator

[Mike K]

I agree with Richard and we should have thought about the thermostat ages ago.

My C8 ( the little CMP 4X2 ) would blow coolant out the radiator cap with some force , usually after climbing a hill. At the time, I was running it without a thermostat .

The thermostat does a important job , but it has a second function, it restricts the coolant flow into the top tank , without this restriction, the coolant fills up the top tank and eventually pressure builds up and it blows out.

I would check your thermostat . Is it the correct type ?

My CS8 4X2 has a different cooling system . They fitted your type to the 4X4's .
