The engine water pump is vital to your vehicle’s cooling system. The primary purpose of the pump is to circulate coolant to the engine block, preventing overheating.
Depending on maintenance, driving behavior, and weather, a typical water pump can last between 60,000 and 100,000 miles. While some people may never have to replace a water pump because of car replacements, others may need to perform the task every five years or so. Discover how to replace a water pump and why you might want to leave the job to the professionals.
Preparing for the Replacement
Before you consider replacing your pump with a Paccer MX-13 water pump replacement or another model, you must consider your skills and knowledge. While a pump replacement can be performed DIY-style, it is not advisable for inexperienced mechanics or hobbyists.
If you are set on performing the swap, you should set everything up before you start working. First, you should buy a proper replacement. Depending on the make, model, and seller, the part can cost between $65 and $130.
Second, you want to set aside or purchase any necessary tools. The essential tools you need include:
- Drain pan
- Hose clamp pliers
- Pliers
- Ratchet and socket set
- Screwdriver set
- Trim and clip removal tools.
Finally, set aside enough time to complete the job in one sitting. A professional can complete a pump replacement in two to three hours. Depending on your skill level, you may want to set aside a couple of more hours.
Properly Installing the New Water Pump
The water pump replacement is similar whether working on a Chevrolet Kodiak C5500 or another vehicle. First, you want to start with a cool engine and your car on level ground. You should drain the engine coolant. Also, it would be best if you disconnected the battery.
Second, remove plastic covers to gain access to the pump. You can use a hose clamp tool to remove the upper radiator hose. Remove the radiator fan shroud. Depending on the layout of the cooling fan, you may need to remove it.
Third, before removing the belt from the belt tensioner, take a photo as a reminder of its routing. At this point, you can remove the belt and the pulley.
Fourth, with the pump exposed, you can remove it. Use a socket wrench to remove the mounting bolts attached to the engine block or timing cover. Tap the pump to break the seal and remove it from its position.
Finally, install the new pump and gasket or O-ring. With the new pump in place, reattach the bolts and follow the above steps in reverse to reattach and recover all engine items.
Replacing and installing an old engine water pump may not sound that challenging, but it is an involved process. If you are a hobbyist or an inexperienced owner, it is best to leave the replacement to a professional mechanic. Contact a local mechanic or auto parts dealer to learn more about the water pump and its replacement. Hiring a mechanic will save you a lot of time and frustration.
