Well, why not try a different tack than the rest of the posts on this site. Set off in a new direction. See the approx 3/8ths water line that comes off the back of the water pump?? Goes to the BAC (man's best friend). Go to AUTOZONE. Look at where they keep the gauges. Look for Metric Adapters. Part number of the SUNPRO adapter is CP7556. It's name is OIL PRESSURE TEE ADAPTER KIT. Don't start shaking your head at me. You don't have to use it on oil pressure gauges. You can use it on any darn thing you wantta use it on. Now what this thing is, is brass tee fitting. It comes with a threaded pipe that can be screwed into any of the three ports on it. Cut that pipe in two, right down the middle. Now screw both halve into the tee. Cut that water hose at a predetermined point and install the brass tee with the now two pipes on the cut hose. Now screw your water temp sensor into the third port on the tee. WAllla. You now have a water temp sensor that can measure water temp prior to the thermostat.
