Toyota Avalon Replacement Parts

Toyota Avalon Replacement Parts

One of the first questions that people ask when thinking about replacement parts is, "Well is there a part available for my car?" Depending on the year of your vehicle, chances are you'll find Toyota Avalon parts for your vehicle whether it's only a few months old or more than six years old. This article will describe the Toyota Avalon replacement parts you may need when trouble arises with your cooling system. Consider it your personal checklist when diagnosing problems and seeking solutions.


Overheating is a common problem that occurs when there's an insufficient amount of coolant in the system. There are many reasons why there isn't a sufficient amount of coolant in the system, but in most cases, it's because of a damaged part.

A damaged waterpump drivebelt or radiator core for example, could prevent adequate distribution. A water pump drivebelt that isn't properly adjusted, or a radiator core that's blocked will fail to keep a car cool enough to operate. So will a dirty radiator grill. Since these two parts are located in the front of a car -- and they're essential to a car's cooling system -- you can understand why it's so important to keep the body's grill in good working condition.

Other causes of overheating could be due to a faulty thermostat, a broken fan, or incorrect ignition timing. If your car is overheating and none of these issues seem to explain it, check to see that your radiator cap has the right pressure.


Overcooling is always the cause of a faulty thermostat.

External Coolant Leakage

Another common problem is coolant leakage, evidenced by a green or orange puddle situated beneath a parked car. To remedy this problem, look for damaged hoses or loose clamps and replace them with their appropriate Toyota Avalon Replacement Parts. Otherwise look for defective water pump seals. Defective water pump seals are at fault if you notice water dripping from the water pump body's weep hole.

Other places you'll want to look include the radiator core and the engine drain plug. If the leakage occurs from the radiator core, be prepared to replace the entire radiator.

Internal Coolant Leakage

An internal coolant leakage isn't quite as obvious as an external coolant leakage, but it can be detected in oil. When you check your oil, look for an oil-like substance that looks milky. If none exists, look for a leaking cylinder head gasket. Then check for a cracked cylinder head.

Coolant Loss

Coolant loss occurs when there's too much coolant the system or when overheating boils it away.

Poor Circulation

Remember that the goal of coolant is to keep the motor operable. This operability strongly depends on a low temperature -- which also depends on adequate circulation. If you suspect that overheating (or over cooling) is the result of poor circulation, check the water pump first. Then check the water pump's drivebelt for damage. If none of these conditions apply, your thermostat is probably stuck.
