Radiator Hoses -the Precautions in the repairing

As we konw,a hose is a hose, right? Well, generally this is true, but not when it comes to your radiator. Most people assume any old black hose from the parts store will do. This is wrong and can lead to hugely expensive problems like engine replacements!

Heat is the biggest threat to your engine. There are plenty of other potential threats, but uncontrolled heat can melt the internal components of your engine in less than 15 minutes. Controlling heat is incredibly important. Keeping your oil topped off is one step. Keeping your cooling system in tip top shape is also incredibly important.

What is the weak spot of any coolant system? The answer is the radiator hoses. These rubber composite hoses are actually very hardy. Still, they are under a lot of strain. The top hose connecting to the radiator is the transport for searing hot water. The bottom hose is put under vacuum pressure by the pump circulating the coolant/water mixture. Frankly, it is a surprise these two hoses last as long as they do.

Being a good car owner, you’ll keep an eye on the coolant hoses. After a bit, you notice they are starting to show signs of wear – bulging, softness and discoloration. You decide to replace them and head down to the parts store to find replacements. This is where things can go wrong. If you are a manly man, you aren’t going to ask for any help. You’ll just size up the potential hoses and go with the version that looks to be the same size as your current hoses. You may have just taken years off the life of your engine or killed it outright. How so? How could hoses make such a difference? Let’s take a closer look.

The two hoses connecting your radiator to the engine block deal with two different conditions. As we mentioned above, the top hose is moving hot water while the bottom hose is moving cooler water, but under a vacuum. You need a different hose for each of these conditions. The bottom hose must be the type that has metal wiring built into it. Why? The rubber will breakdown under the continual vacuum. This will cause the hose to squeeze together and reduce the coolant flow. You engine will start to overheat. At a minimum, this will take years off the life of the engine. If the hose cuts off to much of the flow, the engine can burn up in as little as 15 minutes. Yikes!

The top hose deals with different issues. The heated coolant/water mix coming out of the engine is brutally hot. This is not a good place to have wires. Instead, you want a basic rubber composite hose that can bend. It will be able to take the heat, but will degrade much slower than a wire embedded hose.

Replacing radiator hoses is fairly simple. The only issue is really making sure you have the correct hoses for both the bottom and top of the coolant system.
