Increase CFM on Rad Fans to increase cooling
I am looking for the experience of others who have changed the OEM radiator fans for something that will pull more CFM. I am hoping this is the correct place and saw one in 2.0 with no helpful replies.
Problem, I drive in a mountainous area that often hits 105 to 110f air temp / tarmac. I have added a 2.5 + inch aluminum radiator, new water pump with a (tested) OEM thermostat. With all of this the engine temp will climb to 2/3 rds on the gauge, showing 220 to 230+ on the Accessport. I never let it go for long at that temp as I have already replaced on set of HGs Would like to find a way to keep it at 1/2 or less under stressed driving. Other suggestions from experience are gratefully accepted. Thanks 2006 WRX Wagon 184K Stock block & TD04 Larger TMIC & inlet 3" exhaust

You do realize that while you are driving your fans are off... til you stop and they need to turn on. |

Of course at idle there is no air flow so temps naturally rise and fans will cycle on then too. His issue is beyond normal operating conditions. OP, not a Subaru but I have used SPAL high power fans on my own relay and custom shroud to get more CFM. 230 coolant temp is overheating IMO, I would not be comfortable pushing the car at that temp. |

Aftermarket fans that match OEM capabilities are going to be tough to come by unless you spend some decent money on them (+$400).
What radiator are you running? No decent radiator should be in that temp range under those conditions. |
