That’s why Bar’s Leaks offers a series of time-proven, industry-leading chemical repair products that will keep your cars, SUVs, or light-duty trucks working at their peak potential.

Common Issues That We Can Solve

Cars are complicated machines that need the right level of maintenance and repair to operate reliably on a day-to-day basis. If you own a car, SUV or light-duty truck, you may find that you have to add oil on a monthly, weekly or even daily basis — an indication that you have a leak.

You may also see blue smoke emerging from the exhaust or smoke when your car first starts up. These problems are also indications that your engine (or one of its subsystems) needs attention. Allowing them to go unaddressed can lead to your vehicle having a serious and expensive breakdown.
