Plymouth Satellite 440 Mopar Cooling Q
My cousin has a Satellite with a 440 Mopar which seems to struggle keeping cool.
He bought it maybe a couple of years ago and was fine until it boiled up one day during a steady drive along the A12 back from North Weald with me along side in the Mazda. We stopped at a garage and it boiled, topped it up with cool water and got home ok.
Since then it occasionally gets hot, we also tried replacing the viscous fan with a big electric one but even sitting on tick over yesterday it got towards the hot end so he shut it down.
He has tested the thermostat and it works, flushed the radiator out and doesn't seem to be any restriction, and topped it up with anti-freeze & water.
We don't know the actual tune of the engine, it made something like 300bhp on the rollers and a mountain of torque, but unknown history- I also found a disconnected nitrous line going from the boot to the engine bay (I'm sure it is a N20 line) so I assume it's got some trick bits in it or had gas in the past.
Do you think it could be a head gasket issue or any other ideas? Wants to get it on the road before harvest as he will be flat out until much later in the year soon but not much good overheating!

I would first go for the cheap option and replace the thermostat.
I have had a stat which opened some day and stayed stuck closed other days.
Maybe if your cousin thrashed it at North Weald that day some thing got damaged like the water pump impeller but unlikely if it's an intermittent fault.
