Product Number: 33157800
Cooling system pressure testing on commercial vehicles and buses requires adapter caps sized for the specific filler neck profile — bus filler necks are larger than passenger car equivalents and require a dedicated adapter to mate to a workshop pressure tester. The Sykes Pickavant 33157800 Cooling Cap is the bus-specification adapter from the wider Sykes Pickavant cooling system test cap range, providing the correct interface for pressure testing the cooling systems found on bus and similar large commercial applications.
The cap is part of the modular Sykes Pickavant cooling system test kit ecosystem, where a common base pressure tester is paired with vehicle-specific adapter caps to cover the range of filler neck profiles encountered across passenger cars, light commercials, heavy commercials, and buses. This modular approach means a workshop only needs the adapter caps relevant to its work, rather than separate complete pressure testers for each vehicle category.
For bus servicing in particular, having the correct adapter is essential — substituting a passenger-car or light-commercial cap risks an incomplete seal during pressure testing, which produces misleading test results and can prolong diagnosis of cooling system faults.
The 33157800 is supplied as an individual adapter cap and is intended for use with a compatible Sykes Pickavant cooling system pressure test kit. Other adapter caps in the range cover other vehicle categories and filler neck profiles.
Sykes Pickavant has been supplying professional cooling system test equipment for decades, and the bus adapter reflects the brand's range coverage approach to cooling system diagnostics.
