A/C Coolant Hi-Temp Cutout Switch

[Ed-Mc]

Hi, Fixkick, with the help of your excellent A/C troubleshooting instructions (and a shop manual), I was able to find the problem with the non-running A/C on the '98 Tracker 16V 4-door I bought a couple of months ago.

I guess the previous owner had a problem with the electric fan running all the time, and instead of fixing the problem, they just pulled the A/C fuse to keep the fan from running!!

I was very happy when I checked the little coolant temperature switch screwed into the side of the thermostat housing, and found that it was open (overheat signal). I was even happier when I grounded the Yellow/Blue wire and the A/C compressor ran like it's supposed to!

So, I need to replace that switch. Would you know the mfr's part number or the P/N for an aftermarket replacement?

The manual calls it an ECT switch, opens above 235 deg F.

Thanks for you help and for this website with all its excellent info. I found your timing/adjustments section very useful, when fixing all the problems the Hammer-Mechanic did to the crankshaft gear and other things!!!

Cheers............ed

Thanks for the Suzuki #, it pulled up a lot more results than what I had! A lot cheaper, too. Funny how that works!

I did find an FAE 35670 sensor, if you ever need one in Europe, you can get it from Amazon.uk for L 14.27!! None in the U.S. that I could find.

I have some parts inquiries in, I'll let you know where I got it & what they charged me for it.

Thanks........ed

yes and parts prices , are unlimited. some shops in Florida. charge 400% mark up over retail.

how cool, they have them in Europe.... who is FAE? i guess they don;t market here.

this switch is hard to find.... (for sure fast) from suzuki a 10day wait. is common from some deep warehouse.. not on local selves. be sure to ask , shipping delays, huge, is common.

Just an update, got the switch, you're right, there was a bit of a wait, but not bad. Put it in last week and of course it works perfectly.

The A/C in the Tracker is so cold it'll freeze you out after running for a while. It's been about a month since I recharged it, looks like it'll be ok.

Now if I could just keep the water out of the engine! Head gasket, here we come (unless one of the core plugs I replaced in the head failed; I can only hope!).

great the you found a working a/c overheat switch , (ready for summer)
the head, don't lose the 2 corner head to block, locating pins. hollow tube pins. if lost the cam belt will never run straight.
