How to Replace the Heater Hoses in a VW Beetle

It's normal for heater hoses in your VW Beetle to wear out over time. The upper hose, which carries hot coolant, is especially prone to wear. If this happens, be sure to replace the worn hose as soon as possible, as waiting can cause overheating and serious engine damage. Here's how to replace the engine hose on any model of the new Beetle.

Instructions

1

Lift the hood of your Beetle, locate the two radiator hoses and determine which ones needs to be replaced. If you're having trouble finding the leak, run your hand along the hose and feel for damp places.

2

Remove the radiator cap, and locate the plug on the bottom of the radiator. Put a clean container under the plug and drain the engine coolant. If you are replacing the top hose, it won't be necessary to drain all of the coolant, but be sure to drain enough so the level is below the hose.

3

Loosen the clamps on each end of the hose and slide them out of the way toward the middle of the hose. Carefully remove the hose from the connectors on each end. Take a good look at the clamps, because if they are worn, they should be replaced.

4

Dip each end of the replacement hose in engine coolant and push them into place over the connectors. Slide the clamps to the ends of the hose. Be sure they're at least 1/4 inch from the ends and that they aren't placed over the connector underneath.

5

Make sure the radiator cap and drain plug are on securely, and start the motor. Let it run long enough to warm up, then turn it off. Check the level of coolant and add more if necessary. A mixture of half distilled water and half antifreeze works best.

6

Check the new hose for leaks, particularly on the clamp ends, and adjust them if needed.
