Wax switch on fan?

[lmcintosh]

I have the side radiator on my Dynasty. (1994) I was wondering about the switch that controls the hydraulic fan. I bought the RV new, and wanted to make sure I had an extra wax (not sure this is the name) switch. Thanks in advance. Larry

Just had a fan control module replaced. The part was about $835 + $100 labor. You may mean wax valve, aka thermostat.

I think this is a great thread on the wax valve. there are others - just do a site search for it. http://www.irv2.com/forums/f115/side...nt-148331.html

Odds of the part failing are slim. If it does fail the fan will go to full rpm so it shouldn't hurt the engine but show up on the mpg.

Not sure what part number you have, there is a tag on the thermovalve.

I had to replace my thermovalve after a radiator replacement. The shop contaminated the system and the valve stuck.

I ordered a new valve from Whitehouse Products in the UK. The part number was 553/1/09857/210 THERMO VALVE, and at the time cost ~$265. It took a week to get.
