Warning signs of a worn idler pulley

The idler pulley is a common part that’s found on the majority of the vehicles on the road. Its primary function is to provide tension and guide the engine drive belt. These belts wrap around the various parts of the engine such as the power steering pump, alternator, water pump etc... To keep it simple, idlers are complementary pulleys that make the entire system run smoothly. So, what are some signs of a worn idler pulley? First, let’s start with visual cues. Like many automotive parts, the idler pulley becomes worn over time. The pulley spins against the belt wearing down both parts. This wear reduces tension which can lead to belt slippage. Even more noticeable is a cracked or damaged pulley or bearing. This damage interferes with the rotation of the belt causing torn belts, or the belt falling off of the engine. Without a belt, stalling and overheating of the engine become commonplace. For auditory cues, squealing noise from the engine belt can be a tell-tale sign. As ... read more

What causes my throttle body to fail?

The throttle body is an important part of your air intake system that controls the air flowing into your engine. It’s located between your air intake and engine manifold where fresh air is pulled into the engine for the combustion process. The amount of air allowed into the engine during this process controlled by the butterfly valve. The butterfly valve is a pivoting flat valve controlled by the gas pedal via cable or wire if controlled electronically. When pressing your peddle, the throttle body opens to allow more air flow into your manifold. The computer in your vehicle works with sensors to ensure that your engine receives the perfect balance of fuel and air. So, what causes this perfect harmony to go awry? Let’s take a look at some common issues. Filth, carbon, and dirt can build up in the housing creating problems with air flow. Known as coking, the normally smooth service for air to travel becomes full of gunk and creates an imbalance. This interrupts that perfect ... read more

Why is my radiator leaking?

Why is my radiator leaking?

To avoid catastrophic engine damage, it’s important to keep an eye on your radiator to handle any damage that may occur. The job of the car radiator is to remove heat from the engine to regulate the temperature and prevent overheating. The engine burns fuel which creates a large amount of heat. The engine has to cool in order to protect the entire system. The radiator handles the bulk of this job by keeping the engine running at the proper temperature. It’s important to check your radiator’s water and coolant levels. Most radiator failures trace back to leaking coolant. It’s natural to will gradually lose coolant over time, but a sudden, noticeable dip is an indicator of a leak. Check your coolant(antifreeze) for green or red/orange color with a sweetish scent. Radiator leaks can occur in a few places. Radiator hoses, water pumps, engine blocks, and radiator tanks can all be the source. In the case of hoses, they have the ability to dry and crack over time.
