💡 What is a handy trick for installing a fresh water pump seal without damaging the components?

You get a secure fit when you measure the shaft diameter twice and wipe away old gunk before seating the new part.
- Align the seal squarely against the pump housing so the carbon face sits flush without tipping
- Press it in gently by hand or with light torque so you do not crack the brittle silicon ring
- Verify the bellow moves freely after assembly to confirm the unit can handle normal thermal expansion
