What should coolant temp be to turn on electric fan?
If your ideal operating temperature is 176-180 I’d agree with setting your fan to turn on at 185, that way it kicks on whenever your coolant temperature starts to climb above that temp your fan can keep things in check.
What is the Magic on temperature for electric fans?
If your ideal operating temperature is 176-180 I’d agree with setting your fan to turn on at 185, that way it kicks on whenever your coolant temperature starts to climb above that temp your fan can keep things in check. Are you just guessing at 185°? That’s how I came up with that value. I’m looking for a definite answer.
When does the engine cooling fan return to full speed?
Primary temperature switch stage 2 contacts open when coolant temperature reaches 221 F (105 C) and engine cooling fan will return to half speed. At coolant temperatures greater than about 230 F (110 C), all 3 cooling fans run at full speed. ECM cooling blower, timing control pump and auxiliary water pump are also operating.
What should the temperature be without a fan?
Part number 91064028 has options for fan turn on and off and with the 170 degree thermostat the hot coolant will enter the radiator at 170 and in many cases may cool the engine to this temperature without the fan running.

How does an electric cooling fan work in a car?
However, some longitudinal (front to rear) mounted engines use the electric fan as well, but they usually have an engine-powered cooling fan. The electric cooling fan uses a direct current (DC) electric motor with a thermo switch, module or computer control to turn it on or off, depending on coolant temperature or AC operating condition.
What should the temperature be for a car cooling system?
That means keeping the engine in the 180- to 210-degree F range. To achieve and maintain optimum temperature range, a good cooling system needs the right-sized radiator and fan combo. It must also have the appropriate water pump speed and coolant flow between the engine and radiator.
When does the radiator fan go on or off?
Even kicks on when its a cooler day. Also stays on when driving down the highway. Thought the fan was supposed to kick on when it reached a certain temperature then goes off once the temp drops. Switched out the high and low speed relays and did no good.
What should the temperature of the radiator be?
Check the temperature of the engine block and radiator tank (the one that connects to the engine with the upper radiator hose) using a kitchen thermometer. Make sure that engine temperature reaches about 220°F (104°C) and the radiator tank temperature rises accordingly (meaning hot coolant is being transferred to the radiator).
What should temp be when cooling fan does not come on?
NOTE: if the cooling fan doesn’t come on when the engine has been operating for 20 minutes or more, make sure that coolant is reaching operating temperature, around 220°F (104°C). You may be dealing with a stuck-open thermostat.
How does an electric fan keep the radiator cool?
I want to wire up my old truck to turn an electric fan ON to keep the radiator cool. The ECM has an engine coolant temperature sensor mounted in the engine that alters the resistance to determine coolant temperature.
When does the engine cooling fan come on and off?
The fan will then cycle on and off as needed to maintain the proper coolant temperature. So, The fan runs mostly at idle or low speed when the engine is at normal temperature. Most fans should come on when the coolant reaches about 200 to 230 degrees.
