Hey all.
So I have a 1981 sigma scorpion and for the past 2 weeks she has been running hot.
We have replaces welsh plugs, viscous hub and thermostat.
That hasn’t made any difference.
Mechanic has noticed a small crack in the head gasket.
Would this be the cause of the constant over heated?
What do other scorpion owners think?

Cheers.

Absolutely most likely a head gasket......if Ur good with the spanners, then replacing the basket is great insurance

Before u do so tho....... double check water pump operation, also check level of water, quality of coolant and any blockages in the radiator
