You will need a surge tank tied into your primary circulation system for it to work. The sensor would go in the bottom of the surge tank. Something similar to what is described here: http://www.stewartcomponents.com/tech_tips/Tech_Tips_2.htm -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net] On Behalf Of Dennis Haverlah Sent: Thursday, April 12, 2007 8:34 AM To: Rotary motors in aircraft Subject: [FlyRotary] Coolant Level Probe - Will it work I have an optical liquid level sensor in my air/coolant=20 seperator/expansion tank. It worked OK in tests. After ground testing=20 the engine for about one hour while auto-tuning and taxi testing, I=20 drained some coolant out of the system to expose the coolant level=20 sensor to make sure it still worked. It did not indicate low coolant! =20 I removed the probe and found it had a scum deposit - when wiped clean=20 it worked. My engine came out of a 2004 RX-8 and had 9400 miles on it. My cooland is 60% distilled water and 40 % Prestone - yellow -=20 antifreeze. I have not added any water-wetter but will check today on=20 John Deer's product. The coolant is always slightly cloudy. The engine had some antifreeze in it when I recieved it and I flushed the coolant=20 system. I also changed the antifreeze after about 4 hours of ground=20 operation. Is there any solution - additive to keep the system cleaner, is there a better coolant level dector - or do I need to hire a scum=20 cleaner to keep it clean?? I guess I could give up and just watch the=20 coolant pressure for clues.
