Best Electric Fan for 93 Explorer?

Minx on Fri May 21, 2010 10:08 PM User is offlineView users profile

I can't get this truck to cool well in the summer -- engine or AC -- even with a new Motorcraft fan clutch, upgraded fan, cleaning diligently between the radiator and condenser, tinkering with Water Wetter and the coolant mix, even a new water pump.

I'm ready to try what the Explorer forum guys recommend -- a Flex-a-Lite 180. It comes with a shroud and is supposed to bolt right on. I already have a high-amp alternator to feed it.

Unless you guys have a better suggestion?

Have you looked at the condition of the radiator itself? Are there a lot of bent fins on it or the condenser hindering airflow? Have you pulled off the radiator to see how well it is flowing and check for restrictions? Since it is a factory A/C system the vehicle should be able to handle the load and cool the motor and A/C without any problems at all. Is there any damage to the shroud?

My buddy just went thru a similar problem with his Toyota Tacoma, the truck would run fine but the minute he turned the AC on it would run hot, he replaced the thermostat, water pump, replaced the fan clutch and fan and installed a flex fan, nothing worked, finally he replaced the radiator and now it is perfect, when we leave work he says it takes about 10 miles before the temp gauge needle even moves away from the cold mark.

try starting the truck with the radiator cap off, let it warm up and keep an eye on the water in the radiator, if it doesn't appear to be moving the radiator may be clogged up some where. If they are cheap enough replace it, also see if they have a upgraded radiator (3 or 4 row compared to what ever the current one is now).

Thanks, guys. The radiator is one of the last things I'd suspect because I replaced it two years ago. But I'll have a look.

Be sure to replace the radiator with the OE core size that is recommended for your application. Installing a bigger core size may add to a non-cooling issue like you have now.

I installed a 2 inch core, but I'm not quite sure what was in there before. How would a thicker core lead to less cooling?

I pulled and flushed the radiator, checked the hoses for obstructions, and replaced the thermostat.

Now it cools fine.

Second time the thermostat has failed in three years.
