Hey guys, I was wondering if anyone could help me. I was doing the electric fan install but the fan I bought was broken. So basiaclly I'm running without a fan shroud, was wondering if this was safe and how long I can run this way.
-
I wouldn't run without it on a 4 cyl in the summer. The fan is so far from the radiator that it's not going to get much air to go through the radiator without it.
-
wow...back from the dead...glad to see you are still running your rig (and doing a mod even I haven't gotten around to doing yet... :'()
-
The only problem is overheating the engine when stopped. As oldjeep said, the fan is too far back from the radiator to pull any air though it. In short, it's running without the fan. If it's any extended period of time then I'd throw the shroud back on. Although, if you haven't had any overheating problems, and are only driving it on short trips then you migth be able to hold off.

No doubt, didn't your mechanical try to help out a while back and attempt to leave the Jeep on it's own? :twofingers:
Gomi, good to see you back! :wave:

waiting on a new fan, but probably won't be in for a few days at least, the old shroud is all sorts of cut up as I cut it in order to reuse the radiator overflow and power steering bottles. Been losing sleep over this as my jeep is my daily driver. :'(

In CT...with the weather you have been having...I imagine it would be fine. Keep an eye on the temperature...try to keep moving... :thumb:

Gomi,
An easy way around this (band-aid fix, I know, but it should hold you off until the new shroud get there) is to simply shut the engine down when you get to a stop light. When driving, the radiator gets enough air so as to not need the fan (in fact, my e-fan is off when I'm driving, and nly comes in when the Jeep is not rolling). With the fan still turning, you should be fine for short stops with the engine running, but avoid long waits just sitting still with the engine on. Just be sure you dont turn on the AC (if you have one) until you get the shroud back on.

I am not sure shutting the engine down at a stop light will help any, when you turn your engine off the water pump stops moving coolant, if you kill the engine and turn the key on so the guages come on you can watch the temp climb, as soon as you start it the temp will immediately beging to drop. Just my $.02. As everyone else has already said, keep and eye on it, try to take a route without much sitting in traffic, keep it moving and if it looks like it is going to be a problem try to find a shroud or a junk yard e-fan to get you by until you can get your new fan.
-
keeping the idle up at stop light will increase the speed of the pump and the fan will move air, the optimal would be to keep moving. with all the rain we have been having, and all the cool weather, you will be fine. if you start to over heat pull over and let it cool off you will prob be fine tho.
-
if you have a spare set of rad hoses you can just move it back towards the fan - you could ghetto a frame made of 2x6 (i think it would clear the fan) with 3'' framing screws if you have these around, would look hilarious (if not stupid, i can't believe i am actually suggesting this) but will get the job done.
EDIT: it's a retarded suggestion, but i can't think of anything else quicker other than an actual fan shroud that would keep you safe from overheating - never ran mine w/o the shroud so i can't really tell if it will overheat
-
well, looks like the earliest I can get a fan is wed. Hope it all works out. Wish me luck

If you've been driving it since and it hasn't overheated, you'll be fine for a few days.

Yaaaay! My fine came in today. Its a kit from a company called FF Dynamics. Its a 16 inch fan that covers the entire radiator, has a low amp draw of 9 and a full speed draw of 16, hope this inst too much. I'll try to post some pics when Im done ;)

gomi,
Please let us know how well it works. This mod has been on my list long enough :eek:

no pictures yet, but so far I'd say the fan works well. The positives are definetly noticable, You can tell that there is a bit more on the bottom end, it runs smoother and much quieter than before. I seem to be getting an extra 2 mpg but I may need drive a bit more and keep track of my mpg to be sure. Overall, it is a nice little improvement. As far as cooling goes, it blows a hell of alot more air onto the engine, but temps stay about the same as before, around 205 to 210 but never over 210 degrees.

The temp should not go lower because then the thermostat would close to keep the engine temp, and you seem to be running at a perfect temp. If it does not get to 210*, you are more than fine!

Awesome, the only other gripe I have is with the temp sensor the kit uses, its round and fairly long, much larger than it needs to be with no way of really securing it.

also depends on where you install it (close to the top of the rad would keep the overall temp cooler since it would turn on earlier and not account for the heat dissipation for the coolant passing thru the core even with the fan off). I kind of imagine what you mean by too long maybe you could use zip ties to strap it to the top tank (on the underside of the tank, horizontally, perpendicular to the tubes) that way would make contact to the top tank on the whole length of it and also to the tubes (i'm thinking the zipties would go under the sensor, thru the core between the tubes and over the tank, 2 of them should do probably) and also maybe use some thermal compound to add to the heat transfer (like the one used for CPU coolers) - just a thought, it won't be sticking out like a sore thumb in that case and i would just guess that the heat would transfer better since that portion that is not in the contact with the core would not have a chance to cool.
