Good point, Todd. I hope to maintain an engine operating temp of around 160 F, but I don't know how much this heater will draw out of it. I suppose if it's sucking too much heat out of the coolant, I can run the fan on low or medium and, like you say, run some sort of circulating fan besides. The coolant will flow direct from the engine into the heater, and then over to a radiator (from a Polaris Magnum 500) with a thermostatically controlled fan (kicks in at 208 F). I doubt the rad fan will need to run very much of the time.JDT wrote:Be carefull not to pull to much heat out of the coolant. I have no idea what the min coolant/operating temp of this engine is but 29Kbtu is a lot of exchange.
It's around midnight and I'm still in the shop. Spent all evening building a gear selector indicator. The Sportsman that the transmission came out of had a gear position indicator inside the speedometer, but since I'm not using the ATV speedo, I had to come up with some way of displaying the gear position. I had ordered some LED pilot lights awhile ago for this purpose. The LED's are in five different colors. I'll be installing the LED's in the holes I bored in this chunk of aluminum. I cut up one of my acrylic slat wall shelves to go over the aluminum block and used a label maker with clear tape. The P,R,N,L,H are printed in mirror image and installed on the underside of the acrylic. I'm hoping the colored lights will highlight the letters reasonably well. I'll test it out tomorrow.
