2009 Volkswagen Touareg Coolant Change Cost

While some shops may always recommend a coolant flush, they usually aren't necessary — a regular drain-and-fill will work fine. Always springing for a coolant flush will cost you more money than you need to spend. Here are a few simple guidelines for whether you should drain or flush your coolant when it needs servicing: Check your owner’s manual or warranty booklet to see what the manufacturer recommends. Most will simply say to change the coolant, which usually means a drain and fill. If you have a pretty new car, or you’ve been punctual with your routine maintenance schedule, your car should be just fine with this.  However, if the manufacturer recommends flushing your cooling system at certain intervals, then definitely do it. Make sure that any instructions that the manufacturer specifies for this procedure are followed.  If you have an older, possibly neglected vehicle with a cooling system problem, a coolant flush is the best choice. This is particularly the case if your coolant has become contaminated with corrosion, rust or debris.
