If you receive a 90-degree terminal that fits the mopar coolant sender from aftermarket, I/we want to know where you found it. Most Chrysler senders had 3/16 studs on them while most 90-degree insulated terminals found online fit a 5/32 stud ( Ford/Chevy, etc..).
We resort to finding an old mopar in a boneyard and cut the OEM terminal off temp sender or fuel sender, or kast resort, just put a ring terminal on the wire and attach with a toothed washer and hex nut.
Good luck
