Can anyone divulge details on the Renegade Hybrid radiator system such as dimensions, Inlet and outlet sizes and rad type (number of rows, if cross flow etc...). Is it even allowed ;-)?
This hot summer has proven that my system cannot handle it. I have some good components such as a 2000 cfm, 9 blade fan out of a Ford Taurus. The remote mechanical water pump is a standard R.H. unit. I also have a Griffin radiator, model 125241-H... no radiator cap (inlet=1.5" and outlet=1.75"). https://www.summitracing.com/parts/gri-1-25241-x The dimensions are 16"x 27.5" x 3". it is a 2 row unit. Although the inlet/outlet sizes are different, the hoses carrying coolant from front to rear are all the same size at 1.25 inch diameter. The Tech rep at Griffin seems to think that the rad should be fine but I ain't no 4 core unit either. The other part of this is the car has a Chalon kit installed. I question whether the bumper opening for rad air is sufficiently sized. The opening is ducted to the bulkhead opening. The inner fender walls are fully open to allow the air to exit. From all that I've read; the viable solutions is to either go with a RH rad setup (or as close to as possible) and/or go with an electric water pump. I think I have some (most) of what RH would sell me as there rad kit. The only difference I can see is the rad size/type and the bumper opening size. Pictures of my current setup can be found here: http://www.914world.com/bbs2/index.php?sho...132273&hl=# I feel like I am close to getting this figured out. Just a bit more tinkering is needed. Thanks! |

This is not as complex as it may seem...it is also not necessary to install a tank in the front compartment. I believe you mentioned you have a petcock on the top of the radiator, correct? Use that to bleed the majority of air out of the system up front. Install a fill/expansion tank on the low pressure (return from the radiator) side of the system and higher than the intake/heads - whichever holds coolant at the highest point. I mentioned the advantage of an electric pump originally and I still stand by that as being the most efficient method for bleeding the cooling system. The mechanical pump obviously works but presents more challenges en route to success. Good luck.
PS:The use of a thermostat will also increase the difficulty of bleeding the system. Jack the car up in the rear, if necessary, to help evacuate the air. Tony |
