Apex87 Posted June 12, 2019 Report Share Posted June 12, 2019 Does anyone have any recommendations for upgrading the cooling system? I'm looking for a better radiator, hoses, thermostat, etc.. expecting to have a very hot 3 months of summer and I don't want the engine to heat more. Has been good at a max of 220 but recently jas been getting to 230 today 233. Quote Link to comment Share on other sites More sharing options...
2late4u Posted June 12, 2019 Report Share Posted June 12, 2019 sounds like you have a cooling problem, 2012 have you flushed your rad and cooling system along with new coolant? redtomatoman and jkeaton 2 Quote Link to comment Share on other sites More sharing options...
redtomatoman Posted June 13, 2019 Report Share Posted June 13, 2019 My experience is the radiator is perfectly fine for extremely hot weather. Drove across the Mojave with a bike and surfboard on the roof at 117 F without any significant engine temperature increase. Like the others have stated, rather than try to upgrade, first make sure what you have is working properly. Peace. 2late4u 1 Quote Link to comment Share on other sites More sharing options...
jkeaton Posted June 13, 2019 Report Share Posted June 13, 2019 Flush the system, put in new coolant, maybe put in a new thermostat depending on your year and mileage. Never had an issue with ours even in the extreme heat of summer. If the temp reading is in the normal range, don't worry about minor fluctuations above and below what you consider "normal". If it gets to the point of nearing overheating to potentially cause engine damage, it will let you know. 2late4u 1 Quote Link to comment Share on other sites More sharing options...
14WhiteRTRallye Posted June 15, 2019 Report Share Posted June 15, 2019 4 cylinder or 6? Those 4 cylinders are nuclear reactors! Quote Link to comment Share on other sites More sharing options...
Apex87 Posted June 18, 2019 Author Report Share Posted June 18, 2019 Mine is the 6 cylinder. I'll probably change the thermostat and flush the system and see what happens over a months time with the weather heating up slowly. Quote Link to comment Share on other sites More sharing options...
14WhiteRTRallye Posted June 20, 2019 Report Share Posted June 20, 2019 My fan kicks on at 220 (6cyl) and brings it right down to 208. Quote Link to comment Share on other sites More sharing options...
probak118 Posted July 13, 2019 Report Share Posted July 13, 2019 Just had a coolant flush in my 2012 last April / May at 95,000 kms, Fresh coolant no other issues noted, why mess with something that is already working fine ? Apex87, it has been a month did that do the trick in bringing the temp down to your normal 220 ? Quote Link to comment Share on other sites More sharing options...
