This kit includes 10 hoses; two 5/8 inch heater hoses, one lower radiator hose, one pump to water flange hose, one upper radiator hose, one heater valve to cylinder head hose, one water pump to water pipe hose, one water pipe to cylinder head, one cylinder head to thermo switch, one thermo switch to water pipe, and a water pump to expansion tank hose. Hoses deteriorate over time and it is very difficult to determine if they are about to burst. If you haven't changed your hoses in the last few years, or if one of your hoses has burst, replace them all. It will save you time and money in the long run.
Do-it-Yourself Tip
Volkswagen specifies phosphate/silicate-free coolant in all their vehicles. Our German Pentosin coolant exceeds all VW requirements. While you have your cooling system apart, it's a good idea to replace your thermostat.
