wvo temp control

[GONEFISHINTODAY]

have heated wvo tank with engine coolant.

during towing my engine temps get to 200 - 205ish.

that means my wvo will heat that high also roughly.

wondering if there is a valve that can be placed in line with coolant to close if the temp is over a certain level, then open again when it's cooler? Kind of like a radiator thermostat in the truck.

anyone have idea?

thanks

If you are achieving that with only a heated tank, you must be traversing the surface of the sun, or know something that could make you a very wealthy man. I can get about 85% exchange with coolant heated filter, 30 plate FPHE, insulated lines, and HIH. If you have chosen the correct materials in your conversion, 200*F is not an issue.

With all of that being said, I see no need for such a device you are describing. I also ask this: Do you have a temp gauge on the coolant and VO fuel temp?

I don't think you will have a problem. My veg temps range from 185 to 200 when towing. Never gets any higher even on the hotest day. What are you getting for veg temps?

Please fill out your signature describing your truck & your conversion.

you should be fine, your engine will overheat before you over heat your veg oil. think of hot hot fryers get for cooking. an what burned oil smells like. the flashpoint (vapor) of veg oil is well over 300 iirc.

Heating the entire tank is hard to avoid but its proven to speed poly of the oil resulting in reduced filter life. Poly begines the day the cooks pour it in the fryer and use it. It is accelerated by heat, oxygen and certain metals (hope you have an aluminum tank) I am going to put a couple valves and a T on mine so in summer when its "africa hot" i can bypass my tank with the heat. There simply is no need when its 105* outside. Winter time is altogether a different story.
