Fitting a 300Tdi coolant sender to a 200Tdi

If you want to use Td5 gauges in your 200Tdi, then you'll need to use the 300Tdi green temperature sensor (AMR1425) to give the temperature gauge the correct reading. The only problem is the thread sizes are completely different, so you need to use an adaptor.

The adaptor you need is 5/8" UNF male to 1/8NPT female. The connector on the 300Tdi sender is also a bullet type instead of spade, so the wiring will need a new connector.
