Keeping the Hemi COOL

We finished installing, testing and running this mod and want to share our experience with you.


This mod involves adding an engine oil cooler, remote filte mount, sensors and gauges to cool and monitor engine oil temperature and pressure.


How it all Started


We noticed that with the addition of our steel front bumper, it blocked off a lot of the radiator air flow, compromising the cooling efficiency of the radiator.


Depending on the design of your front bumper, you might notice your coolant temperature is getting hotter than before.


We gave that some thought and wanted to address this issue.


We started by adding electric pusher fans to the radiator but were not satisfied with the results.


So, we wanted to address the core of the problem and really come up with a bright solution that is more fundamental and offer more performance benefits.


The Mod


This mod helps the radiator cooling efficiency, by adding an extra, thermostatically controlled, engine oil cooling circuit to the Hemi engine oil.


We built an oil exchange cap that mounted in place of the oil filter. AN10 hoses take and feedback engine oil from the cap to a thermostatically controlled remote oil filter mount.


We then had to mount the thermostatically controlled oil filter mount to the WK frame. We chose a 93°C pellet that stabilizes the oil temperature at 105°C.


We mounted our engine oil cooler in front of the radiator with 3 SPAL pusher electric fans and 2 SPAL puller electric fans that are switch controlled manually.


To be able to measure the results of this mod, we added a pressure and temperature sensor and a digital gauge monitor to keep track of engine oil temperature and pressure.


We had all our hoses custom made and decided to use AN10 size for all hoses


This add-on circuit stabilizes engine oil temperature at optimal level, even when towing or pushing it hard, and adds an extra measure of safety and longevity to your engine and engine oil.


We love this mod, and invite you to consider doing it if you want to crank out more performance, get more longevity, add that extra margin of safety or improve the cooling efficiency of your engine.


Please shoot us any questions you might have. This is just our pet project and is not a product of JeePerf.


We will be happy to share our experience with you and assist you in selecting its components if you decided to implement it.


Enjoy.
