Comments about CARQUEST by Dayco Curved Radiator Hose:

This is the perfect lower radiator hose if you have a 6KV chassis Polo Variant from Greenland, with a AEB 1.8T 20V engine. Direct fit when using a B5 VW Passat / B5 Audi A4 thermostat housing outlet, with a european market Polo/ Golf/ Jetta non-air conditioning radiator. Thanks for this hose the car is enabled to nevar lose, and is close to Jeep 4.0 levels.[...]
