Radiator fans

[DMCMW Dave]

Yes, The otterstat is mounted so that the terminals are pointed down. I guess the other sensor that may be causing the issue is the coolant temperature switch. Since I dont have any means of actually testing the temp of the coolant, I suppose I should just get a replacement of each......

The coolant temp switch in the engine has nothing to do with the fans. It enriches the fuel mixture below about 30F. Actually it is electrically parallel with the full throttle microswitch.

Besides, that one is a huge PITA to replace.

This is a great tool to have

Dumb question- where is the otterstat located, as I know my fans aren't coming on.

Does the coolant temp switch also run the temp gauge in the car?

Left/driver side of the engine, next to the frame you'll see an aluminum pipe - look on the underside. Should have 2 spade terminals connected to it

No, the temperature sender is on the right, forward side of the INSIDE of the block - uses a ring terminal.

You can take it out of the car, put an ohm meter on it (will read wide open), warm it up to 200 degrees and see of it closes (zero ohms). Kind of a lot of work.

Definitely a lot of work for a fifteen dollar part NOS from Houston.

Got it. Looked it up too after I posted that as well. Thanks! I'll have to take a look when it comes back from DMC CA.
