I've had Ron Davis build me two radiators. When I did the first one, I tried to get the fan shroud and electric fans, but was told that the distance from the engine to the radiator was too close for it to work. (Second radiator, I just used to number and had a duplicate made.) What is the dimension from say the front of the radiator to the back of the electric fans on yours, I want to measure. Thanks.
I don't know as the radiator is off site with other parts I have but I know it will fit with room to spare.
It has two SPAL fans in the shroud and they are high capacity. The radiator is made of 2 cores but each core is a full inch.....this is equivalent to a 4 core but actually less deep. The shoud and the two fans are actually LESS deep than the original shroud and belt driven fan. If you call Ron Davis they can probably give you all the dimensions. If not, I can try to have someone measure it for you.
Finally reoriented myself to your pictures. The first one (Ron Davis logo) is not a picture of your radiator? And the other two are upside down? Looking at the location of the oil cooler inlets, were you planning on using something other than stock lines? The lower oil cooler port lookes to be 3 to 5 inches lower than normal to accommodate the fan.
You are correct the first picture is the "stock" photo from Ron Davis the other two are the actual radiator. This IS a brand new, never installed radiator.
The coolant line locations are all stock. The oil cooler lines are NOT for the engine oil but for the tranny oil (good eye).
When I spoke with Ron Davis they highly recommended NOT cooling the engine oil directly in the radiator as they thought it was "not enough" and it could overload the coolant system. I don't know if I agree but if it's true that could explain why so many people complain about cooling problems with their trucks.
To compensate for this Ron Davis can fab a oil cooler that is either fan cooled or cooled with and exchanger that uses engine coolant. This would still dump heat into the coolant system but they explained it is more efficient and the cooling system can handle this "better" than the OEM design. I also have the oil cooler for sale.
The radiator and the oil cooler are made for "performance" application and likely overkill for most our uses but I'm an overkill kind of guy.
As someone already pointed out you can easily recore your OEM radiator for a bit less. But I would rather pay a little more a get what I think may be a better system that arguable may last longer than the OEM even with the recore.
The Ron Davis radiator I'm using is on my 110 Double cab with the 4.6 which has a performance cam and computer chip. I just like the electic fans built in I haven't noticed any issues with the oil cooling. In the stock 97, the tranny cooler is a little thing and the oil cooler is integrated - one would think if the transmission heat or the oil temp was an issue they would have used that opportunity to switch it. BTW- where were you going to put the oil cooler?
You can mount it anywhere you want but it looked like the ideal spot would be on top of the passenger chassis rail next to the wheel well. It's a heat exchanger so it doesn't use a fan.
Agree, that in most set up's the OEM is more than fine. I think the problem is that some of the tubes block up over time and this then decreases the efficiency. Even if you flow test in that situation I don't think you can tell if only a few are blocked up.
The truth is all three cooling systems ideally would be separated--like on my other car. But obviously there are space and cost constraints.
