Still running warm 215 maybe ?????

[dkbanjo]

I dont know what to do. I would be greatful for some feedback. I have a 91 mustang with 83,000 miles very clean and I've put a new aluminum radiator, water pump,
hoses, cap, and 180 thermostat, 100amp alter with 3000 cfm fan and air dam. It had been running cool for awhile then my hi-6 box went bad so i disconnected it since then its been running warmer like 215 but really it goes up and down a lot and i havint been driving hard because I've been breaking in gears. Should i go back to mechanical fan or what will i really lose that much power i dont think so. thank you in advance for feedback.

If it runs at 215*F while at speed, the fan isnt the issue anyhow.

If temps only creep up when stopped/going slow, and they drop once underway, then the fan might be at fault.

Good luck.
