Issues with Plastic Coolant Pipe in Porsche Cars
10 Jul, 18
What does the plastic coolant pipe do for your Porsche?
Your Porsche’s cooling system is a critical component of your vehicle, as it is responsible for keeping the engine’s temperature regulated. This helps with engine performance and function, but it also prevents parts from wearing prematurely. One part of the cooling system in your Porsche that is especially important, as well as any other vehicle, is the coolant pipes.
Coolant pipes are designed to transport antifreeze/coolant/radiator fluid back and forth from the engine in an effort to keep its temperature stable under driving conditions and protect it from extreme heat. The coolant pipe is responsible for taking the heated coolant out of the engine, circulating it through the radiator to bring down the temperature of the fluid significantly, and then re-transport the fluid back to the engine to cool it off. As you can see, the coolant pipe is a critical component of the cooling system, without which drivers would be left with an overheated or severely damaged engine.
A Porsche Problem
Coolant pipes in the Porsche Cayenne V8 from the years 2003 to 2006 are made of plastic, which has been a long-standing, well-documented issue in the vehicle. The coolant pipes create problems eventually for drivers, as they tend to crack and leak coolant over time. There are a number of reasons why plastic piping doesn’t work well in these cars. The most probable reason is that the plastic material of the piping is especially susceptible to excessive heat, which essentially melts the pipes and causes the driver to have to replace them prematurely. The location of the piping is problematic, as it is exposed to high temperatures consistently.
Symptoms of coolant pipe issues to look out for
It’s critical to constantly observe how your Porsche is performing, as simply being aware of issues and bringing them to your automotive specialist in a timely manner can offer several of the following benefits:
• Retains the value of your Porsche
• Keeps your Porsche running smoothly
• Prevents hazardous part failure
• Saves money in repairs in the long run
Attending to the symptoms of coolant pipe failure is critical, as it could lead to overheating or serious engine failure if it goes unaddressed. The symptoms of coolant pipe failure are as follows:
• Visible coolant leak beneath car
• Issues with the starter motor
• Visible coolant leak in starter
Your car contains various fluids that perform different functions for your vehicle; coolant is one of them. Therefore, it’s important to be able to differentiate between coolant and other fluids so that you can accurately relay the symptoms to your automotive specialist. Coolant in a Porsche is usually a bright-colored pink or red fluid, and if you notice it collecting beneath your car then it must be attended to immediately.
How to fix the issue
When the plastic coolant pipes fail, there is no other solution other than to replace them. Luckily, Porsche has developed a replacement part that is far superior to the plastic version. Aluminum piping as a replacement has shown to be a much better alternative, and a long-lasting solution. A replacement procedure should be performed only by a Porsche specialist to ensure the part is installed properly.
What you can do to prevent problems with the plastic coolant pipes
It is best to take a preventive approach to all automotive issues – especially ones that are unique to the specific car you drive. For instance, it’s probably a good idea to have your coolant piping checked out and replaced before the part fails on its own, potentially causing damage to other parts. Here’s a brief checklist of what you can do to help prevent issues with your coolant pipes:
• Have a Porsche specialist perform all maintenance, repairs, and part replacements
• Replace the coolant pipes with the proper parts
• Perform regular inspections of the cooling system
• Follow your Porsche’s designated maintenance schedule
