This range covers engine and transmission seals, gaskets, door and window weatherstrips, body sealing strips and tape for Kia, Mazda, Nissan and Volvo.
A seal fails in one of two ways: it hardens until it no longer conforms to the surface it presses on, or it wears until the lip no longer contacts the shaft. Either way the leak starts small, as a mist or a stain, and gets worse as the fluid washes out the remaining lubrication. Weatherstrips fail differently, by perishing and shrinking so a gap opens at the corner.
Check for oil mist around a seal housing, drips on the ground after the vehicle has stood overnight, water in the footwell or boot after rain, or wind noise that started without any impact damage. When you replace a shaft seal, inspect the shaft surface for a wear groove where the old lip ran; a new seal on a grooved shaft will leak again.
Listings give the position, model years, engine and drivetrain together with the OEM part number. Seal diameters are not interchangeable, so match the number rather than measuring the old part.
