I got a fan from the junkyard. It works, and when I swap the wires, it works backwards. Which is good, because it is too big (thick) to go between the radiator and the pulley that used to hold the fan. If I mount it in front of the radiator, and wire it backwards, will it still be as efficient as if mounted behind the radiator? I recognize that (I think it is Bernoulli's Principle) by forcing air through a slightly smaller cowled outlet will cool it a bit as it leaves and expands, but by putting this constriction before the radiator, will it cool as well as if mounted afterwards? Overall, I think this will have a minute, if any, difference, but just wanted to see if anyone has mounted in front of the radiator with success. The fan/cowl is from a Ford Taurus, I think. It was just laying there next to the car. It is larger than the Mav radiator, and has a 16" 6-blade fan in a 21X16 cowl. It fits really nice and snug if mounted on the front of the radiator, behind the grill.
I'm hoping the one I picked up will work, it's out of a 90-91 escort wagon. The motor is flat on the back side and the shroud fits the radiator pretty good. I believe the motor has a hi and low speed so I will have to get a diagram cause the motor has 4 male blades at the connection. I could just touch them one at a time to a battery, but I would rather know which is supposed to be which before doing so.
I think Dennis...Mavaholic mounted his in front of the radiator. Are you going to put it on a thermostat or a switch?
Fan blades are like an airplane propeller. They are designed to spin in one direction only. Reversing the wires will give the proper direction for airflow but it will not be as effective. Some electric fans are designed to spin in either direction. I would say factory ones are not. Only way to tell if its going to be sufficient air flow is to try it.
Gene Did You Get The Connector Also If So I Can Give You The Wiring All I Need Is The Color Code And I'll Look On My Alldata
THis is it just sitting in there, no modifications to the mounting hardware, and not mounted. Just pulled the grill off and shoved the fan in for estimation of space.
Darn! I don't have it cause I took it out of my moms car and it was the wrong one(year application) when she got the car. I bought her the correct one at the yard and didn't think to look for and get the connection cause at the time I had no need. Thanks for the offer though, maybe there is a diagram that shows the connections. Gene
Does anybody know if I can wire it to the bottom rear screw in the voltage regulator. It is hot only when the engine is switched on and running, and do not know if it will affect recharging of the battery, or draw too much off the alternator. IF not, any other suggestions for hot wires, without making a new one? I have an in-line 30AMP fuse on 10 guage wire. I want this running all the time when the engine is on, just like the stock fan. In TX, cannot get too much air running through the radiator...
90 escort w/ 1.9 is what my mom has and the fan came off of another escort im sure, but not exactly sure what yr or engine size. Might try like one or two yrs up/down with 1.9 or the other offered is 1.8. My moms escort harness has 3 wires and the fan I removed has 4 blades, the extra wiring was also removed when I did the exchange. I think she has a pcm problem that is either the origional overheating problem or was created when the wrong fan was wired in. My scanner never shows a fan request but the temp does show too hot and the guage in the dash does go to red. Hey scooper, I suggest running independant wiring so as not to risk your harness or other components.
Gene With Air ? If So The Wiring Goes Thru A Relay With Br/y Being Hot And Bk Grd Relay Is Turned On By Pcm ,(i By-passed The Pcm) Put The Relay In Mine And Also The Temp Switch 212:f In The Top Of The Thermo Housing As Mine Runs Cool Right Now All The Ford Escorts Show Br/y As The Feed Wire Without Air Its A Straight Run From The Fuse Panel Thru The Thermo Switch
I bought a 30amp relay (for fog lights) and will try to run a hot wire directly from the battery line with an inline 30amp fuse. It will run whenever the engine is on. Hooked it up to the old A/C powerline today, but it tripped the 30amp fuse in the fusebox (under the dash) because it was running both the heater fan and the cooling fan.
I have a general question, not intending to hijack your post. A friend of mine was working on his Toyota Tercel-80 something. He added a new radiator and electric fan. It was not running correctly and he wanted me to look at it. The wires were spliced together on that fan and when it came on it was blowing forward. Meaning, it was sucking air through the radiator from the engine compartment and blowing it out towards the grill. Do some cars have their fans equipped this way? Seth
