Why maintaining your AC System is very important:
Heating and A/C systems may break eventually with usage. The hose pipes may clog and drip if not serviced, causing reduced efficiency in heating and cooling capabilities. Regular maintenance will keep your AC system operating at peak performance!

Indications your A/C system may be having issues:

  • If your air conditioning blows only slightly cooler air compared to the exterior air

  • Air that blows in smells damp and musty, or like mildew and mold

  • Your cabin does not warm up in cold weather or is just a little warmer than outside

  • The defroster takes longer than typical to operate, or does not operate

A fan belt, also known as a drive belt, is a belt connecting your car's engine to the front-mounted accessories. The fan belt rotates the water pump and engine fan, which maintains a cool environment for the engine and its components. Sooner or later, your vehicle's fan belt will dry out and crack. When you are ready for a replacement you can count on us for all your vehicle's repair needs. You not only have to get the belts replaced with quality ones but you should have the work done by experts.

Coolant System Flush
A car's coolant system transfers excess heat from one part of the engine and finally loses it through the radiator fins. With time, the coolant becomes old and dirty. Radiator fluid, better known as coolant or antifreeze, keeps your radiator cool, as you might expect. Car engines run hot, especially in warm weather, and without something to dissipate the excessive heat generated by the engine, your car can overheat and fail very quickly. To make sure the system is working effectively, consider having a regular coolant system flush. Over time, your radiator coolant can cause radiator corrosion, rust, scaling, or other debris that you do not want in your car’s radiator or engine. A coolant flush resolves this problem – it’s basically a blood transfusion for your cooling system. A flush involves forcing several gallons of cleaner, water, and new antifreeze through the system to get rid of all the old antifreeze and the contaminants that may have built up in it. A coolant flush is basic maintenance for your car's cooling system. Call 210-341-1171 or visit Seymour's Garage at 8411 Speedway in San Antonio, TX 78230 for all your coolant system flush and fill needs.

Hoses transfer coolant and antifreeze throughout the engine's cooling system (including the radiator). Sooner or later, your vehicle's hoses will dry out and crack. 
You not only have to get the hoses replaced with quality ones but you should have the work done by experts. The mechanics at Seymour's Garage will thoroughly inspect your car's hoses; replace all worn hoses, and adjust the installed hoses.

Radiator Flush
A radiator is the part of your vehicle that keeps the engine cool and protects it from excessive heating. To be cool, the radiator needs to remain clean - always. With time, sludge, rust, and other solid deposits build up inside your car's radiator. These can clog the cooling system and make them less effective. This in effect hurts your vehicle's performance. A regular radiator flush is enough to keep the system in shape. For this reason, make the radiator flushing a part of your routine car maintenance schedule.

Radiators are heat exchangers for cooling your car's internal combustion engine. A radiator cools the engine by circulating an engine coolant through the engine block - it then loses the heat to the atmosphere through radiation. A radiator has a set of tubes through which the engine coolant flows. Fins surround these tubes. When the radiator fails, the excess heat produced by the engine could damage the engine components. To prevent this from happening, have your radiator serviced regularly. Your radiator needs to be handled by experts, visit Seymour's Garage today.
