Thermostat 190 Degree Bypass

Balanced sleeve high flow thermostat that matches the OE designed thermostat that is required for reliable service in 1988-1995 6.2L and 6.5L Diesel engines as used in GMT400 trucks (new body style). This fits the housing that has the thermostat pointing directly up underneath the outlet. This also fits single thermostat units that have the 4-bolt outlet used in P-Series Vans.
