A vehicle's drive belt is a critical component in today's cars and trucks. Often referred to as a serpentine belt, it's a single belt that weaves its way through, over, and around numerous pulleys that drive many different components. A drive belt is usually responsible for powering the alternator, water pump, steering pump, AC compressor, and exhaust control components. Serpentine belts are very robust and normally last from 45,000 to 75,000 miles before needing to be replaced. Telltale signs that your belt is reaching the end of its useful life are squealing or screeching sounds. When you hear things like that coming from your engine compartment, have your belts checked out right away. In addition to being left stranded if it breaks, they sometimes shred when they fail in such a way that they make a tangled mess within the pulley system and it takes a lot of time to clean it all out before installing a new replacement one. This shredding condition is usually seen in belts with misaligned pulleys or tensioners, older belts tend to do it as well.


La Palma Mobile Mechanic technicians see torn and leaking hoses quite often.  One of the first signs of a failing hose is white smoke.  The coolant is leaking out of the hose and turning to steam as it hits the super hot engine or exhaust system.  In other instances, if the car hasn't been driven too much, the coolant won't even get hot enough to turn to be forced out under pressure and in those cases, you'll just notice a puddle of coolant (usually green) under your car.  If you see this, you know you've lost some of your coolant, and it's important to not drive very much without having enough fluid in your system.  Driving your car without sufficient coolant can cause internal engine damage like blown head gaskets or even warping the heads of the engine, especially if they're made of aluminum.  Make sure to take care of coolant leaks at the first opportunity by calling us and getting it or any other needed auto repairs checked out.

Importance of Belts and Hoses

Belts and hoses play an important role in many systems of your car including the cooling system, air conditioning, alternator, radiator, heater core, and others.  As they are constantly exposed to extreme heat, vibrations, and chemicals they have some of the shortest lifespans of any other vehicle components.  This is one of the reasons why regular maintenance is so important.  It affords vehicle owners the chance to have experienced mechanics look things over and catch problems before they turn into real nightmares.  Since belts and hoses tend to dry out over time and crack and break, it's important to catch these weakened and worn parts before they completely fail to avoid potential vehicle breakdowns.  Sudden failure of a hose or belt can leave you stranded and needing a tow truck.
