I have a Koyorad (formerly Koyo) N-Flow radiator and a Ford Taurus electric fan waiting to be installed in my turbo RX-7. I'm using the Taurus fan because it moves a ton of air, it's nearly indestructible, and it's cheap. The Taurus fan shroud might be too wide to seal over the new radiator, though. How would I go about shortening the shroud, in case I need to hack it up?
Second question: FCs are known to have electrolysis problems with the cooling system (read here if you're unfamiliar with the issue). The PO remote-mounted the battery in the storage bin behind the passenger seat, so I obviously won't be able to put a probe on the negative battery terminal and reach to the cooling system. How else would I test this? Can I just push a probe into the negative battery cable?
Sound af you need to run a redundant engine ground.
I know the FCs have a redundant engine ground when the battery is in the stock location, but I will have to check to see if the PO made one. I haven't checked.
You're buying new coolant, right?
Cut up the coolant jugs to make strips of plastic to cover up the overhang. Drill bit and zipties to hold it to the shroud and the radiator, if you can't just use rivets to hold it to the shroud. (Zipties flex more than rivets, so you need to ziptie the loose side to the radiator to keep it from flapping into the fans)
Cooling system electrolysis problems are almost always caused by people not changing their coolant. Change it every year and you'll have no problem. Technically, aluminum radiators should have a small ground strap from the core to the chassis.
