ContiTech offers its Pro Series Plus Timing Kits, which are designed to allow technicians to perform timing belt and water pump service. These kits come with either an OE-style plastic or a metal impeller. ContiTech also offers kit versions with new water pump housings. ContiTech Pro Series Plus kits also include cam and balance shaft seals. ContiTech said it uses seals that match all of the OE specs for ID, OD, and width. All components are covered by a warranty that matches the original manufacturer’s belt replacement interval, according to the company.
