I just replaced my coolant sending unit in my bd220 engine. Napa's replacement was a 1/4" npt unit. I believe mine is a 3/8" npt. The install required a reducer bushing. The probe is completely surrounded by the bushing and doesn't protrude below it. The old sender also had a longer probe.
My temperature gauge is reading hotter, in the 3/4 needle range. Before it read in the 1/2-5/8 needle range. I am concerned the engine is running too hot.
Is the bushing causing a hot spot around the sending unit? Is the fact the probe is shorter causing an inaccurate reading from not being completely immersed in a moving stream of coolant flow?
None of my local parts stores had a listing for the exact replacement sending unit.
Btw, the contact clip broke off my old unit while I was removing the sending wire for my harness install. I glued it back in with super glue. Seemed to work fine, but was concerned about accurate readings.
Thanks
