Old Topic - New idea?

[OneFast600]

It’s been discussed many times on these sleds as to where one of those silicone, stick on oil pan heaters should go. I have one on the bottom of the engine and it has little to no effect when it’s -25*C out. I have a Yamaheater in-line coolant heater, but nowhere useful to install it.

Has anyone thought to install a 4”x5” 250W silicone oil pan heater to the front heat exchanger? It’s a nice, flat surface to mount one. Or would this be another wasted effort?

Here is a pic of the area I had in mind.

I dont think it will help. You need the heat in the motor.

Why do you say there's no place useful to install the inline coolant heater? Install it in the hose from the front of the motor to the thermostat hose and it should warm the coolant in the cylinder head & block until 165 degrees when the thermostat would open.

Is this the hose behind the oil separator? I looked at that but didn’t think it would work well with a bend in the hose

I don't have the best picture, but that steel bent elbow, that hose should work if you can fit it into that hose.

Ok. I’ll have a closer look at it in a day or two when I get some time.

Perhaps a little, but not entirely unorthodox for this application, could be to heat the fuel and intake air prior to starting.

My idea was that sticking one of these heat pads to the front of the heat exchanger would allow heat to rise through the coolant, just like an inline heater is supposed to through the lower rad hose.
I haven’t had the time or ambition to tackle installing my inline heater where SRXSpec had suggested.
