What causes my clutch to slip?

The clutch is the part of your vehicle that connects two or more rotating shafts. It transfers rotational power from the engine to your wheels in manual cars. The clutch allows us to engage a spinning engine to a non-spinning transmission by controlling the slippage. When the clutch engages everything spins together. Once you press the clutch pedal the assembly disengages. So, what causes your clutch to slip? Similar to braking systems, clutches use friction material on the clutch disc. Just like with brakes, over time this friction material wears off. So, unfortunately, most clutches will slip and need to be replaced eventually. When your clutch slips, it disengages and limited power is being transferred to your wheels to drive your vehicle forward. Wear and tear over a period of time isn’t the only factor that can cause your clutch to slip. Extreme heat damage, a disc covered in oil, or improper step and cup dimensions can all be the source of a slipping clutch. There are many ... read more

What is a canister purge valve, and how does it function?

The canister purge valve is a vital part of the Evaporative Emission Control System (EVAP). The EVAP system seals the fuel system of your vehicle to prevent harmful fuel vapors from entering the environment. In particular, the canister purge valve is an emissions control component that allows the engine intake vacuum to take the exact amount of fuel vapors from the EVA canister into the engine intake manifold. In newer model vehicles the purge valve is electrically operated solenoid controlled by the engine computer. When your engine is off the valve is closed. Once your engine is up and running the computer continuously and moderately opens the purge valve. This action allows fuel vapor to move from the charcoal canister to burn in the engine. A hose connects all of these parts to form the EVAP system. Like many automotive parts, dust and dirt can clog the canister. The purge valve can even crack from harsh conditions in the environment. If the purge valve fails, it can cause problem ... read more
