Radiator Bottom Hose Replacement

In order to send your cooled coolant from the radiator to the engine, it has to travel through the radiator bottom hose. This hose is prone to wearing out over time, this is due to the constant pressure and heat cycles. You don’t want coolant going on the ground instead of the engine, so get the bottom hose fixed as soon as possible.

Air Intake Replacement

In order to get air into your engine it first passes through an air filter which is connected to the intake plenum. The air intake is the system from which air gets from outside to inside the engine. It also houses important sensors like mass airflow sensors and intake temperature sensors.

Cooling Fan Replacement

In order to keep your car's engine cool, calm and collected, your cooling system uses a cooling fan to move air through the radiator and cool the coolant. Over time the fan can become damaged or can just wear out. It’s a really important part of the cooling system so if there’s a problem then it needs to be solved as soon as possible.

PCV Valve Replacement

Your PCV valve sounds like a very complicated thing. In reality it just lets some pressure out of the engine. This pressure is built up due to the engine's rotations and heat, the PCV valve is responsible for venting this pressure into the intake.
