A bad water pump rarely introduces itself with one big, unmistakable problem. More often than not, the cooling system starts acting a little off. The temperature creeps higher in traffic, the coolant drops without a clear explanation, or a strange noise starts coming from the front of the engine. Since the car can still seem drivable for a while, many people keep putting it off. That delay is where a cooling system problem can turn into engine trouble. 1. Coolant Keeps Dropping One of the first clues is a coolant level that will not stay where it should. You top it off, check it again later, and find the reservoir low again. A leaking water pump can let coolant escape through the seal or weep hole, sometimes slowly enough that it does not leave a huge puddle right away. A small coolant loss is easy to shrug off at first. It still points to a problem somewhere in the system, and the water pump belongs high on that list when the level keeps falling. 2. The E ... read more

Brake fluid is a vital component of automotive brake systems – it uses hydraulic pressure to transfer pressure (amplified) from the brake pedal to the calipers that press the brake pads against the rotors to slow down your vehicle. Brake fluid requires regular replacement – typically every 2 years or 20,000 miles. Working under high temperatures, over time the fluid loses its chemical and mechanical properties. Increased water content further accelerates this deterioration. Water content?! Yes, brake fluid is highly hygroscopic – it absorbs moisture from the environment. Over time it can absorb so much water as to become less effective, and in severe cases (because water boils off at a lower temperature than the working temperature of the fluid) the water may boil off causing braking problems.   At South Denver Automotive we offer comprehensive brake system maintenance, including brake fluid testing and exchange. We can inspect your vehicle’s brake fluid ... read more
