This kit includes 9 hoses; two 5/8 inch heater hoses, one lower radiator hose, one upper radiator hose, one heater valve to head, one water pump to water flange hose, one water pump to water pipe hose, one cylinder head to thermo switch hose, and one thermo switch to water pipe hose. Expansion tank hose if your car is equipped, is sold seperately (#4460). 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.
