Bought a 94 Mustang 5.0 from a couple of guys toally focused on performance. I think they got carried away. They threw out ANYTHING with weight.. Spare tire, console & the list goes on. I'm working on getting it back to a nimble daily driver. They have done many mods I don't understand. I last played with muscle cars in the early 70's & then focussed on heavy equipment... Todays technology baffles me. In their quest to go faster the boys before me put in a toggle switch to control the radiator fan. At my age I can't remember to use the toggle.. :smash:
They are feeding it with a wire from a toggle on the dash board spliced to a heavy red wire going to the fan. My dash pod had no temperature gauge/musta been a light. They installed an aftemarket gauge. I look out on the engine and the Chiltons manual references two temperature sensors. One by the distributor,left side and one on the lower intake manifold, right side. I'm guessing one of those controls the fan, the other the former light, now the gauge as both have the factory clip on connections on them? I'm guessing their aftermarket gauge is electric & they used aa aftermarket sender that came with the gauge & the same wiring until they got to the dash pod where they connected to the new aftermarket gauge. Out where they spliced into the fan wire bundle they cut off & capped a heavy orange wire with a blue stripe. Then they cut & capped a heavy red wire & hooked their wire from the toggle switch into that red wire to power the fan. I'm thinking MAYBE if I hook the original wires back up POSSIBLY the cooling fan may again function on automatic. If so on a 5.0 engine, at what temperature should the fan turn on? That I guess would be my first test on seeing if splicing things back together works. Did I read somewhere the operating temperature is 200 degrees F ? The factory temperature gauge if I were to have one would give no numbers, just a safe zone.... Any help or knowlegeable technical advice with this issue would be GREAT thank you!!!!
