My turbocharged 660cc with a clutched fan runs way, way too cold. I've attached a K-type thermocouple to the water temp sender near the thermostat housing to give me temperature readings on the cheap, without messing with the cooling system hoses.
Starting up at 29.9 C, idling with the headlights and AC on leads to 44.4 C after 5 minutes.
While driving, temperature never exceeds 58.0 C.
At a stop after a bout of driving, idle temperature never exceeds 72.4 C.
Cooling system has an 82 C thermostat and is running G48 HOAT coolant in 55/45 concentration with distilled water.
Fan clutch locks solid at startup as expected, but only gets marginally disengaged over the 5 minute warmup period. It's effectively locked solid.
A quote for a brand new fan clutch from Aisin was north of Rs. 100,000 (~$300) so that absolutely won't do.
The engine is underpowered and undemanding enough to cool that I think converting it to an electric fan, relay-operated temperature-sense setup will
- Free up low-down horsepower and torque - I have so little that every bit counts
- Free up revs
- Make less noise
- More accurately maintain engine target temperature
- Allow for better fuel economy
I'd like to hear any thoughts. I'll document the conversion here if I choose to move forward with it.
