Went for a spin the other day to Bourton-on-the-Water. Approx 75 miles each way , with a mix of motorway/ a roads. Got a little concerned with high water temperature , particularly on the return trip .( spent 5 hours at Bourton, so plenty of time for it to cool down).About 20 miles from home , the needle was alarmingly close to the red , so decided to pull into services. As it has the original thermo-couple (?) fan , the fan stopped when the engine was switched off. Thought that i may be better off continuing the journey at 50mph rather than chance the engine cooking whilst stationary. The temperature did dip slightly , but rose again on a steep incline about 8 miles from home. Very,very hot by the time i got home. Checked water flow, seems to be pumping ok , no loss of coolant , no binding of brakes, no apparent damage to hoses. Car is only used in summer , and i was wondering if it would be of benefit to replace the fan with an electric one , and what type ? Is it worth removing the thermostat ? Any ( sensible ) ideas please.
