Answers to Commonly Discussed Dodge Coronet Radiator Hose Issues

You may have noticed that the most discussed problems in car forums and discussion boards are those with the radiator assembly. It seems like every bit in the radiator assembly can cause you problems; in fact, they can, even the radiator hose. If you type "radiator hose problems" on a search engine, you would get dozens of forums created for it. So to save you from the repetitive and, sometimes, wrong answers, here are the solutions to the common problems observed with your Dodge Coronet radiator hose.

Cracks and scratches

The easiest problem to notice is the steam coming from the assembly which is usually caused by a crack on the hose. Cracks or cuts can be caused by either the heat or the ozone-but mostly the heat. If the cracks are soft or the hose is somewhat mushy, then they are caused by the ozone. Avoiding all scientific explanations, we say that ozone is just a natural gas present in the environment but they are more evident in extremely air-polluted areas.

A minor scratch can also cause the hose to leak. Road debris, pebbles, and rocks may have hit the hose when you took it out for a drive; the hose may have also been rubbing against another part in the radiator assembly. These two cases can cause the scratches which, if left unattended, can lead to a bigger crack.

Hose bubbles

Another complaint by car owners is the bubbles or bulges on the hose. This is caused by the swelling of the hose due to oil from the engine, lubricants, or brake fluids. These chemicals make the hose soft and appear to have tar on it. The bubbles are normal things to see after some time; the recommended way to solve them is a replacement.

Falling apart

The worst thing that could happen with the hose is if it just fell apart or collapsed. Every time the engine revs up, the hose needs to be stable enough to support liquids and coolants. If the hose is too soft (caused by too much wear), it can collapse and get detached from the assembly. This isn't much of a problem with newer car generations but older generations relied on a spring to hold the hose in place. So if you have an older generation car, the spring is likely loose.

It's impossible to not have problems with your car's radiator assembly, no matter how expensive the parts you have are. Radiator problems are like women's post-menstrual stage or teenagers' puberty stage. So rather than us condemning you for how poorly you took care of your radiator assembly, we tell you to just get yourself up and solve the problem part by part. Here are some tips on how to prolong the service life of your radiator hose:


Flush regularly


As you may know, your Dodge Coronet radiator hose is constantly exposed to coolants, lubricants, oil, road debris, dirt, and whatever it is flying around in the air. The main point is that a lot of things go through the hose or reach the hose-things that can build-up and clog. A blocked hose would not only affect the performance of your car's engine, but it is also dangerous since we're talking about chemicals improperly mixing and getting heated here.


We recommend that you get the hose flushed at least once a year; you can have your trusted center or mechanic do this for you.


Check the connections regularly


Aside from flushing, we recommend that you take a look at the hose clamp connections every six to eight months. The connections may get loose after some miles and drives on rough roads; this could cause the radiator hose to get detached from the assembly. A simple check and, when needed, a retightening of the bolts and readjustment of the hose would be great.


Don't let the hose to stay on for too long


Although newer hoses are sturdier, we recommend that you replace it after three to four years. As a rule of thumb, radiator hoses need to be replaced as a pair (the upper and the lower) and need to be replaced every time you replace the other coolant hoses. Doing so ensures a coordinated lifespan as well as better compatibility. Also, every time you replace the radiator of your car, we recommend that you change the hoses as well for the same reasons.
