Hello everyone I was wondering if it would be any benefit to my 1983 mercedes 240d to upgrade the cooling system components. What I mean is to replace the thermostat (with one that is rated to 80C or 176F), install a 9 blade fan and fan clutch off of a 300sd to replace the 5 blade fan, and to install a 300sd water pump pulley which is smaller than the stock 240d pulley to overdrive the waterpump and increase the flow of the system. Also a new temp sender because mine is old and the temp gauge reads a little off because of it. Later in the summer this year I will give the car its second cooling system flush also. Any thoughts appreciated!
