Volkswagen Polo Service & Repair Manual: Engine Cooling
| Because towing places higher demands on the engine cooling
system, the cooling system is enhanced in vehicles that have
factory-installed trailer hitches, if necessary. This is done by
installing a stronger or a second coolant fan and/or a larger
radiator. Vehicles designed for hot climates and/or with an A/C
system already have the enhanced engine cooling system. In the
Passat, a stronger coolant fan (PR number 0Y2) may also be
installed alone at the factory. This makes it easier to install
a trailer hitch later. |
| The cooling system should also be enhanced when a trailer
hitch is retrofitted, if the system was not already modified at
the factory. Otherwise the cooling system could overheat under
increased engine load, for example when driving in mountains, in
high temperatures or with high towing weight. When converting
the cooling system, use the engine cooling system components
designed for towing listed in the ETKA electronic parts catalog.
Refer to the procedures in the applicable repair manuals. |
| Enhancing the cooling system may only be avoided if the
engine will only be under moderate load, for example: |
| the combined weight is considerably less than the permitted
amount, |
| no high outside temperatures, |
| no driving at high altitude. |
| The coolant temperature gauge must always be monitored
closely. If the needle in the gauge moves high into the hot
zone, reduce speed immediately. It may be necessary to take a
break to allow the engine to cool. When doing this, let the
engine run at idle for approximately 2 minutes to prevent heat
buildup. |
 Note
| In vehicles with an A/C system, switching the system off
will reduce the load on the engine cooling system. This also
improves vehicle acceleration and makes passing other vehicles
safer. |
| If the cooling system is not enhanced, the seller must
inform the buyer when selling the vehicle. |

If the traffic behind the trailer cannot be seen in the standard exterior
rearview mirrors, additional exterior mirrors must be installed. Both exterior
mirrors must be installed on folding mounts and adjusted to provide a sufficient
range of vision behind the vehicle.
