You could have pulled a bum radiator. I did extensive flushing on mine and it was still full of crap when I replaced it last september

 

I ran a few bottles of Prestone radiator flush through it and suddenly my over heating problem disappeared. Thanks for all the help guys!

 

glad it's fixed!

 

On a side note, if you want to run an electric fan, you can buy an electric fan thermostat switch kit at autozone or any auto parts store for between 15 and 20 dollars. It has a probe on the end, and you attach it to the radiator hose. It reads the temp and tells the relay when to kick the fan on and off. You can adjust it for any temperature in your normal operating range. I think I bought mine at advance auto parts.

 

Is it worth the money? Seem pretty reliable?

 

That's the only way you should put in an electric fan. Just rigging a flip switch is stupid. Plain and simple. For 20 bucks its plenty reliable. The first one lasted several years in the ranger until eventually the relay failed and it stayed on all the time. I bought another and replaced it, and it worked until I yanked the motor for a 4.0 or 302 swap. I'm still waiting on the cash to drop a new motor in, but I saved all the fan stuff so I'll be putting it back in.

I ran the first one with the probe inside the upper radiator hose. I ran the replacement one zip tied to the outside of the hose and covered in heat tape to keep it from getting gunked up. Both setups worked fine.

 

Where did you get the E fan from.... or what vehicle and year

 

Just keep an eye on your heater core, i had the same problem untill i found out that water was not flowin threw the heater core

 

My fan came from a performance shop, it's a flex-a-lite fan with shroud. At the time it was the best fan available, and it was around 300 bucks for the full setup with the fan, shroud, thermostat switch, and wiring. But a lot of people use the electric fan setup from the taurus and the thunderbird. You can get everything from a junkyard and fab up your own fan shroud mounts.

 

Taurus and Thunderbird huh that's a idea seems more my budget as well thanks and anyone whose done this message me pics and directions so I'm not fabing for hours
