The cooling system can become a steaming, fire breathing (well maybe not fire breathing but you get the message) monster, if the internals are gummed up with sludge and contaminates that can occur on older machines; especially if any of the previous owners used the wrong (cheap?) coolant.
To be sure of a fully functioning cooling system, renew as many of the various parts you can afford, that may now be terminally blocked or suffering internal corrosion.
This item and some of the parts below may be required to achieve a fully successful overhaul and a better looking cooling system, especially when nice new fasteners and clips used.
Add as many items as you wish to the same shopping cart, new cap 110650969 & clamps 921710261 for example, and still only pay the same single fixed price shipping cost. Try this pro-workshop gasket sealant 08CRAHLG120G; top quality with easy application. This component may have other applications within the Kawasaki model range, so please make sure you order the correct part number for your application.
