98-07 Dodge 5.9L Cummins Water Bypass Kit

Fits 1998-2007 Dodge Cummins 24 valve & Common Rail cylinder heads.

Stainless Diesel's water bypass kit relieves excessive pressure in the back of the engine.  The water valve opens between 45-50 psi. Engines that turn high rpm's create high pressure in the back of the block that causes freeze plugs in the block/ cylinder head to blow out under 'higher than stock' hp applications.

This kit has a hose that runs from the thermostat housing to one of the coolant plugs near the back of the cylinder head.

Kit includes:

  • Polished aluminum thermostat spacer - (with mounting hardware / o-ring)
  • Braded stainless steel AN #8 line (with fittings on both ends)
  • Brass water bypass valve (adjustable from 50-100 psi)

Stainless Diesel part number: WBPK1
