GMC Sierra 3500HD Thermostat Housing Kit - Wehrli - Billet - Deore Gold - 08-10. A top-outlet billet housing and upper coolant pipe that re-routes flow upward and forward on 2008-2010 Sierra 3500HD Duramax.

Supports single or twin CP3; dual CP3 or dual alternator trucks use WCF100424. Not compatible with 2006-2007 GMC Sierra.
