JFP, Looks like according to there site. The tool is included? I just need to purchase the gasket.
Price includes new low temperature thermostat insert manufactured in Germany by one of the same manufacturers that makes the oe thermostat insert, allowing you to reuse your original housing. Gasket (1 required) sold separately. Includes the special tool required to change insert out. Provides increased cooling capacity increasing power while ensuring consistent performance and extending engine-component longevity.
