Cooling system

[Carl23]

Hi All,

I have just bought a 1971 3.0si, when i run the car at stand still for about 5 mins, the temp gauge goes up to the middle quite quickly, one side of the rad is hot and the other is cold.

I was thinking about the followng:

replace the water pump, replace the thermostat, flush the rad, and system, add good quality coolent.

Does any one have any recomendations, as far as i know all the parts on the car are original stock. The rad looks fine I just don't want to hit any overheating problems.

Also when does the fan kick in.

Many thanks Carl

it could be many things, but since you just acquired the car, it would be a good idea to replace the items you stated. also, it could be that your radiator is clogged or a faulty fan clutch. you don't have to purchase a new radiator since aluminum radiators can be serviced. remove it and take a to a radiator shop ($50 max).

Hi Marko,

Thanks for the help, I have also found a small leak in the rad so I am going to get this re-cored as well. So apart from the fan that should be good overall of the cooling system.

Cheers Carl
