With the summer heat coming up, get ready because it’s time to keep your car running cool with a few basic concepts. One of these key ideas are for you to replace your water pump, a preventive maintenance measure that will help keep your car running at a cool temperature. We stopped and talked with the good people at Edelbrock, and they offered up a few pointers to help dissipate the heat that is sometimes created from the chrome plating we Lowriders like to add to our engines. They also told us that overheating is usually caused by the water/fluids not flowing fast enough throughout the engine, and this can occur during stop and go traffic or when sitting at idle when cruising.
Why start off with a water pump? The answer is simple; the purpose of the engine’s water pump cooling system is to remove excess heat from the engine and to keep the engine operating temperature at its most efficient level. Most of the liquid cooling system removes about a third of the heat that’s produced in the combustion chamber. The exhaust system removes the biggest share of the heat, however, while the internal parts of the engine such as the cylinder walls, pistons, and cylinder heads, also absorb large amounts of heat. If these parts of the engine get too hot, no oil in the world will protect it. The cooling system prevents the internal engine parts from melting due to the heat of the burning fuel. If your engine runs too hot, the pistons will expand so much that they can’t move in the cylinders, resulting in a seized engine. Another common example of overheating involves the head gasket blowing because of the heads expanding due to heat blowing out of the head gaskets.
Most of today’s engines run better once they warm up to the correct temperature, something that should happen as soon as possible after starting. The right temperature for your engine is so important that most of the engine builders that we’ve talked to say that 220-225 degrees is the ideal temp to run your engine, this is usually hard to do with all of the chrome goodies under the hood, but it is not impossible.
Excessive heat under the hood of lowriders has always been an issue, but with the help of the Edelbrock pros we’re going to try to give you some cooling pointers for your Lowrider and go over some of the benefits that their water pumps will give your ride. Now follow along, as we take a look at the Edelbrock line of water pumps.
1. Not cool!
2. When we stopped at Edelbrock, they showed us 4 different finish versions of the water pumps that they had available. Edelbrock has water pumps for several applications, from short small block engines that we are showing you to Ford, Dodge, and the latest LS applications.
3. From left to right you have the water pumps polished, natural, black-coated and the Lowrider popular Enduroshine finish.
4. Edelbrock’s water pumps are designed to flow and if you take one apart you can see the pride that goes behind the designs and machining involved.
5. The water pump propeller has gone through several improvements in its design. This latest design is made to channel a high volume of coolant through the engine.
6. Here is Edelbrock’s water pumps flow chart in comparison to a Chinese import.
7. The import water pump featured a propeller design that restricted the flow.
8. You can see that they leave some of the casting, which will affect the flow of the coolant.
9. All of the Edelbrock crate engines are equipped with their water pumps to ensure that the engines run cool.
10. This Ford small block received a new black-coated Edelbrock water pump.
11. Here is a polished short Chevrolet water pump on a small block 350.
12. They also have long neck water pumps for the Chevrolet small block. To see more applications look them up on the web.
