The Audi 100 was a mid-size luxury or executive car model manufactured and marketed by the Audi division of the Volkswagen Group. Classic parts like the heater core parts contribute to the success of 100. The heater core is filled with cold liquid when changing to gas, causing the vehicle to produce cold rather than hot air into the vehicle. The heater core is generally cooled by a mixture of water and antifreeze that travels through the engine. The coolant can then be distributed through the heater car and produce some heat into the cabin.
100 offers practicality to customers. But there will be problems after heater core parts have been used for years. The heater core parts are needed to help circulate hot coolant through the passenger side of the cabin and allow hot air to get into the vehicle's interior. The most common signs of bad 100 heater core parts include: a sweet smell inside of the vehicle, cold air when the heater is turned on, coolant puddles inside the vehicle, and the engine overheating/running hotter than normal. It is easy to buy new 100 parts at nearly wholesale prices. There are much better and smarter 100 products and devices."
