Tim - good advice - hadn't thought of the lack of water flow.
Another problem with the tee connector, or even finding a spare plug in the coolant system - From what I read from the Teleflex instrument website - Yanmar used a PT 3/" 19 (thread) ffitting for their sensors, and the common auto shop tee connectors, and water temp sensors ate NPT 3/8" 18 (thread). Talked to a couple of plumbing shops, who had never heard of the 19 thread. Does anyone have any info on this? Is it possible to get fittings and sensors that are 3/8" 19 ??? Or was a Yanmar specific thing?
Teleflex says you can re-tap to 3/8 18, but would that be worth the risk. What type of metal or cast iron, is the thermostat housing made of (ie how soft is it) and would it be fairly easy, or hard to re-tap?
