Radiator Fan speed

Well I checked over my motor since I got the thermostat and rad cap replaced AGAIN since the one I put in 2 weeks ago were junk and I noticed that my driverside fan spins good, sits flush and is closer to the radiator. I then looked at the passengerside and the fan wasn't spinning at the same speed as the other side, has a slight wobble to it, and it looks like it sits more away from the radiator as the other fan sits closer. Any thoughts?

Re: Radiator Fan speed

Pull the fan assemblies off of the radiator and check the nut that holds the fan blades to the shaft. Take it off and pull the fan blades off the motor shaft, check for wear. Also check the the bolts holding the motor to the shroud.

Re: Radiator Fan speed

Ok I'll check the blades tomorrow. Also whats the proper voltage for the motors as I might as well check that stuff too. Thanks

Re: Radiator Fan speed

The fans run at I think three different speeds depending on different parameters. But they should run at the same speed.

so...

....when are you gonna do your HG's

I'll do them when hell freezes over Like I said it's fine know after another new T-stat and rad cap, but I want to go over ALL things related to the cooling before I even hear HG.

Atta boy! BTW have you tried the block tester kit yet? I hear your HG's are leaking like a sieve

Seriously though, id replace the pass fan then, wobble on any rotating object affects efficiency and speed by increasing centripetal resistance. A slower spinning fan hence cant pull as much air, and our grilles are restrictive enough.

Edit: Irk yeah I forgot about the fan nuts..... In my humble defense I "sleep" in a room with a cat and 4 kittens, about 3 hours a night nowadays

Re: Radiator Fan speed

Yeah they are 3 speed. Check your fuses if the mechanical inspection of the fan doesn't show anything. On some cars there are two fuses but if one is blown that fan will still turn, just much slower. Kinda like how one low beam blown fuse causes that light to be dim but still on.

Re: Radiator Fan speed

I believe the fuses are good but i'll check again. The fans came on when I opened the hood at normal temp that's when I noticed the wobbly pass. fan and that it wasn't going the same speed as the driver's side.

Re: Radiator Fan speed

Well I took out both fans and the pass. side feels like it has more resistance than the driverside fan by turning them by hand. Also I don'tnow if this is correct or not but the pass. fan has 4 big blades and the driver side has 5 skinny blades?

Re: Radiator Fan speed

Yeah, not sure of the reasoning behind the blade design, but they are different.

Re: Radiator Fan speed

I also forgot to mention that the pass. side fan blade which has the wobble to it had about 4 stress cracks about .5 in. coming around the metal insert where the bolt goes.

Re: Radiator Fan speed

the fan on the passenger side is the one for regular cooling of coolant. The driver's side is for the extra capacity needed when the a/c is on. Lucky for you, the fans are interchangable (I only run one fan, the passenger side (of course) on the lemons svx). Switch the fans and keep your a/c off and see if the car still overheats.

Re: Radiator Fan speed

On mine the driver side stays on most of the time and the pass. side shuts off with no a/c or anything on.
