Blanking Plug for Water Bypass

A genuine water bypass hose rubber blanking plug, can only be used on the cylinder head tube when deleting the bypass hose (GZA2086) between the water pump and cylinder head.

Alternative blanking plug - 88G619 - unscrew the bypass tube and replace.

You will need to swap the water pump to the (GWP187) which has no bypass tube outlet.

The water bypass hose circulates cooler water to the thermostat, allowing the heater to warm up faster, perfect for those cold winter mornings!
