im fighting the heat battle too. but my front air dam is missing, so thats most likely my main problem. I flushed the radiator and the engine block at the same time I was replacing the thermostat. ( a lot of poo came out ! ) when flushing radiator there is still junk built up inside the engine block, and the thermostat will not allow it to circulate unless you remove it and flush the engine block at the same time. I installed 160 deg thermostat until my new front air dam arrives
I agree with the inspection and cleaning of the ac condencer and radiator cavity behind the shroud. mine was dirty as heck. just be real careful not to damage the lines. I realley like my ac in south fl.
as for the coolant, I do not use any antifreeze. if you go to pepboys they sell this big gallon tin can of coolant additive , much like watter wetter, but it specificly is designed to work with only water. and it has better cooling properties than antifreeze / water mix.
after doing said above my ride is driving around town at less than 210. averaging somewheres around 200. wich was a drastic improvment from the 225 / 230s it was running at before
now I have a question for you guys, :
I only have one fan. its a puller behind the radiator. and its wired to come on when I start the car ( even if the car is cold ) but I never hear the fan kick on to high. I think its just hotwired to run on low speed always?
can someone put a digital test meter on their fan when its on low and high and post us the numbers its powered at for both? because id like to run a switch to manualy turn high power on my fan but dont know where to start. and knowing the power it needs on high will tell me where to begin.
