JK Heavy Duty Radiator?

14693 Views 25 Replies 12 Participants Last post by  scottgoodman988

I have a 2010 Jk with 37's, I'm having a issue when I get about half ways up a mountain, I start smelling anti freeze, the temp gage moves a little but not much. What I would like to do is to replace the factory radiator fan and replace it with a heavy duty one. Does anyone know of a good after market HD fan?
Or any ideas please?

I have a C & R Radiator and it's an excellent product. That think was packaged very well to protect it from shipping and was perfect when I received it. They do a lot of NASCAR builds.
Yeah I remember the Ron Davis radiator was around $1500.00 but i think it came with two Spal fans. These radiators are definitely not cheap and I was concerned the $300.00 ones wouldn't hold up. My AEV radiator never leaked and I still have it but I was looking for more cooling capability.
Brings up an interesting conversation:

1. what is the cost without the SPALs?
2. what is the cost of getting something like a Camaro SS fan set up? (I believe that is what Motech is recommending now)

I'm not sure. Originally I thought with two fans I would have one running all the time on the trail for some airflow and then both when the temp was 210*. That involved a controller and more cost. When I talked to the C&R folks at SEMA they said keep the Pentastar brushless fan as it was the best one they tested. I saw the Camaro fan on Motech's site and I think they were similar in price and would require a set up procedure for the fan to run. I think the airflow is similar but Camaro fan is a little more quiet. I'm old school and I would still prefer a belt driven fan for trail use and a more consistent temperature.
