This kit includes 7 hoses; one hose from heater core to block, one lower radiator hose, one water pump to head hose, one water pump to water pipe hose, one heater core to cylinder head hose, one expansion tank hose, and an upper radiator hose. This kit does not inlcude oil cooler hoses. (If you have an oil cooler make sure to buy #10507 which includes two oil cooler hoses.) 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.
