Where is the thermostat sensor on a suzuki samurai?

Answer 1

There are actually 3 things on a Suzuki Samurai I can think of that you might be asking about...all three are around the same place. 1. The traditional thermostat that opens when the engine coolant heats up, to start allowing coolant to flow through the radiator and get cooled down. (If there was no such device all coolant would flow through the radiator even when the engine was cold in the winter, greatly increasing the time for the engine to "warm up.") 2. An electrical sensor (actually a heat-controlled varistor, a resistor that changes it's resistance based on heat) that tells your car computer how warmed up the engine is. 3. Another electrical sensor (varistor) that goes to your temperature gauge on your dashboard. #1, the thermostat, is where the upper radiator hose goes to the engine. If you follow the fat hose off the top of the radiator, it goes to a fitting mounted at the top of the engine, near the front, on the passenger side. I think there are 3 small bolts that hold the fitting the hose attaches to, to the engine itself. If you remove this fitting you will find the thermostat mounted inside. It is a circle with a suspended fitting that can move up and down. If you want to test the thermostat, take it out, put it in a pot of water on your stove with a thermometer, and start heating the water. When you see the thermocouple move, look at your thermometer and see what temperature activated it. #2 & #3 are units bolted into the engine right around the same place (slightly below if I remember correctly) where the thermostat is located. There will be two wires into each fitting. I don't remember which is for your computer and which is for your temperature gauge. Hope this helped! Paul H.
