This kit includes 8 hoses; one upper radiator hose, one lower radiator hose, one water pump to water pipe hose, one water pump to oil cooler hose, one water pipe to oil cooler hose, one cylinder head to heater core hose, and one heater core to block hose, and one expansion tank to water pipe hose. This kit includes the 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.
