Hi all,
I did the taurus fan conversion on my jeep, and it runs fine at first, but after going up a few hills and putting the jeep under load the temp starts to climb. If I put the fan on high, the temp still climbs but much slower. It doesn't start dropping until I park and idle for a while. If I keep driving the temp will climb slowly and stay right on the last mark before the red on the guage.
I should mention that I am a newspaper carrier and I use the jeep to make my deliveries, so there are a lot of stop-and-go's and not much natural air flowin' thru the radiator, so I figured this would work better than the stock setup. I replaced both the electric and the mechanical fans with the taurus 3.8L fan. I have it wired thru the $75 NAPA relay. I have the factory single row radiator - maybe this is my problem? The cooling system is functioning properly - new water pump, hoses, rad flushed, new t-stat.
I decided to experiment, and moved the taurus fan over to the side instead of the center of the rad, and put the factory electric aux. fan next to it. I wired the factory aux fan up to a different switch. This setup works very good, the jeep stays cool unless I floor it up a hill for a few minutes, but it draws way too much current from the alternator. I have offroad lights on my jeep as well as other accessories, and the draw from both fans running is HUGE. When I turn them on everything dims, the idle drops and the volt guage drops to below about 12v.
I don't want to build a complicated system, so what I wanna know is this -
1. Should I get a 3 row GDI radiator and go back to just the taurus fan?
2. Should I go back to a mechanical clutch setup and install the 3row rad?
3. Should I keep the 2 electric fans and get a bigger alernator or another battery?
Any input on this is greatly appreciated.
