coolant temperature sensor and the fan switch

Postby j.maclean » Tue Aug 17, 2010 1:02 pm



Hey there, I am going to flush my coolant and change my thermostat as my bike is running hot. I was wondering where I would find the coolant temperature sensor and the fan switch as I would like to check and clean the connections in the process. (84 Aspencade GL1200) Thanks!

Youi will have to remove the right side fairing lower to see them. To get to them will require removing some of the small sheet metal pieces and then you might, if you have small hands, be able to reach them on the thermostat housing.

You can also take off the 2 bottom bolts that holds the radiator to the frame to pull on it a few inches to give you a lil more room ......

To reach the sensor isnt as easy, it is located behind the bulkhead and requires removal of the radiator.

If your noticing higher than normal readouts on the gauge, your problem possibly isnt the sensor/sender or even the thermostat.

Regular flushing and replacing the coolant can prevent buildup of harmful deposits which can result in water pump failure.

A leaky head gasket can show up as higher temperature and not necessarily show coolant in the oil nor oil contamination of the coolant.

A smell of coolant on start up after running the engine till it is warm then shutting off for 10 minutes can be a telltale sign.
