The original radiator was was due for replacement. Many collapsed fins, corrosion, etc so I opted to replace. Considering I was going to be relocating to a much hotter area I went with the Flexalite with the three e-fans.
Motor is stock with the exception of the Hesco hi flow water pump.
Ambient temp averages about 103' during the day.
At idle the XJ does great. It will sit between 198' & 202'
At speeds up to about 35MPH it runs at 209'-211'
Above speeds of 35MPH the temp rockets upwards of 225'. I imagine it would go higher but when it reaches the mid 220s I take action to cool it down such as reducing speed down to <15MPH or stopping completely and letting it just idle. This is all without running A/C.
Coolant mix has been played with 70/30 & 50/50. I didnt see the bottom hose collapsing from the Hesco pump but I swapped to a reinforced hose anyways. Plugs are new with proper gap. No know vacuum leaks. Air burped with drivers side elevated.
There is a winch however, it sits pretty low leaving the upper 2/3 of the grill exposed. I also have hinge blocks installed so the rear of the hood is elevated about 1.5" allowing for air pass through.
Rad install was strictly by the book.
It really seems backwards to all overheating problems I have ever experienced. I don't know if it is load related or airflow related.
Any ideas?
Thanks in advance for any input!
