Where to buy temp-activated switch that screws into thermostat.

[AlaskaFestivaGuy]

89 LX carby. Radiator fan runs continuously. I thought replacing the temp-activated switch would be the most likely solution, else the relay.

I took the switch (see photo) to O'Reilly. They have nothing with a blade terminal. Where do I buy this part? It has "1H25" stamped on it.

I've found several old threads on this, but nothing cites a source.

If it does turn out to be the relay, I notice that the '89 schematics show a 6-contact relay. The group of three relays (see photo) adj to the battery each have only four terminal positions. What gives? Are the schematics (which I downloaded from this site) specifically for 1989 incorrect? Or are none of these 3 relays the one for the fan motor? I don't see any other relays in that area and have even removed the battery mounting platform for better access.

Autozone should have this sensor.

That took all of a minute to find on their site. A lot of the 'Mcparts' stores have employees with no motivation to use other key words for a search.

Shows currently unavailable online, but they should be able to use the number to see if it's available from their 'hub' or possibly cross reference.

Hope this helps.

Go to Mazda Parts and buy a thermo switch

I use a standard bosch sensor for just about anything. It might be handy having them the same someday .

OK, I'll bug O'Reilly down the street again this a.m., else Mazda about 10 miles away. Thanks.

jeez...relay not senser! severe lack of italion espresso

I bought -- for a shocking $42 -- the part from O'Reilly and installed it. Now my radiator fan runs only when it should.

For future reference, I'd still like to know which relay in the group of three (if it's one of them at all) is for the fan motor. Is there anything like what is used for a printed circuit board, called a "component placement" diagram, which tells, using the component names from the schematics, where each of them is located in the vehicle?

Rockauto has 'em for cheap! There are two different sizes so make sure you get the right one.
