150amp alternator
I needed the extra juice to run my elec. fans, upgraded the big 3 wires while i am in there as well. AC stays cold even during stop and go traffic and idle since my elec. fan ramps up to 60% when AC is on....Temp around 185F avg, with the 4000 CFM units.
I did all my accessories belts on the 3FE this weekend. These were last changed 30k miles ago.
AC ice cold now, no slippage, Elec. cooling fan is getting proper voltage with the new 150amp alternator and everything is working wonderful.
Obviously the correct AFM is working. As for CEL, there could be a numerous reasons, i think you have other issues that are unresolved. Pull the code and see...
your kick down cable needs adjustment, its way off!! Should only be 1-2mm from the stop.
Also if your tranny fluid isn't burn, i doubt you overheated it. A440F is fully hydraulic, so very sensitive to fluid level....
I am pretty sure this was the same rig my buddy sold. We did Sierra Trek back in 2024 and he was behind me the whole time....i have many pictures of it on doing all the Winch Hills....
I had a Ron Davis, a CSF, a 93+ TYC( Yes it fits my 3FE, 2 Lilands.
I still have my Liland 2 core alum. and it cools every bit as good as my $2000 Ron Davis...might not look at pretty, but i definitely would stay away from CSF copper/Brass...
True,. There are reasons why i moved to California...for the weather. But i have taken my rigs to many cold places, over 5000 miles and my windows are slow, but , nothing we cannot deal with..
I have replaced radiators on my 91 like 5 times during my 10 yrs of ownership. You will get used to it and it will be like changing oil......
Many from trying new aftermarket radiators and a couple times due to user errors...
