As we know oil is the lifeblood of any engine and keeping the oil in good condition is paramount to the well-being of your engine. By simply replacing your original dipstick with the oil temperature dipstick, then attaching an 18 inch wire (included with the kit) to the oil pressure switch. You can monitor your engine's oil temperature without the use of a gauge.
Your oil light will now serve two functions, it will continue to operate as an oil pressure warning light as before, but will now also become an oil temperature warning. In normal conditions your light will remain off, if the light starts flashing then your engine temperature is getting too hot. If the light comes on solid, then your engine temperature is definitely too hot and you should stop the engine.
So now when you are chugging up a long incline or you are sat in a traffic queue you can actually tell when the oil temperature starts to rise, and before it hits a critical temperature you can do something about it. Saving you time off the road and lots of money on engine rebuilds.
