Description

The Lisle 35650 is a heavy-duty thermostat seal installer designed for most CAT, Cummins, and Detroit Diesel engines in Class 7 and 8 trucks.

This tool features a double-sided centering bushing that guides the seal driver, ensuring seals are installed straight into the recessed port of the thermostat housing. For seals without a stop flange, the handle acts as a stop to set the seal at the correct depth.
