Overheating issue with 1994
Hi I recently acquired a 1994 ford explorer. There was no overheat issue I just chose to proactively do some preventative maintenance and upgrades at the same time. It ran good but had an original radiator etc.
So. I put in an AlloyWorks 3 row radiator, new acdelco water pump, new thermostat housing, thermostat, proform brushless 14” efan which flows 2900 cfm.
As soon as I got everything installed and running I immediately started having overheat issues. I bypassed the heater core to see if that was it and it helped but I am still seeing high temps with the AC on. Much higher then I saw previously before all the work I did. I’m starting to run out of ideas. Does anybody have any suggestions or path to choose moving forward? I have tried with no thermostat, 180 thermostat, 195 thermostat and there is no difference.
If I’m accelerating hard with the ac on it will climb to the “l” rapidly. Thanks.
