Keep Your Air-Cooled Porsche On The Road
If you own a classic air-cooled Porsche then you you have a great car. One that you would like to keep running for many years. But as the Summer months are upon us, you run a higher risk of overheating your car.
How can you keep your car running cool, even in weather that can be well over 100 degrees. Well, we’ve put together 5 tips to keep your pride and joy on the road for a very long time.
5. Don’t Warm The Engine By Idling
Many air-cooled owners like to warm up their engines. Warming the engine is a good thing, but if you do it while idling the oil pressure also stays low.
In an air-cooled engine the oil helps keep the engine cool, so if pressure is down it can’t help with the cooling or lubrication. Because of this it is usually better to drive the car, but keep the RPMs low before the engine fully warms ups. In general that would mean keeping it under 3,000 RPMs and in some models under 2,500 RPMs.
What you want is to keep the oil pressure up, but to make sure that all the engine parts warm up to the same temperature before driving it a bit harder.
4. Clean Your Engine
Part of keeping an air-cooled Porsche from overheating is making sure that the heat is dispensated from the engine. To help keep this working at its best it can be helpful to clean and degrease your engine.
Not only will it look great, but more heat can be removed and more cooling air can get to the motor if grease isn’t blocking parts of the engine.
3. Change Your Oil
Since oil is a large part of cooling an air-cooled Porsche, it is always a good idea to change your oil before the hot months. When changing your oil you may want head over to your Porsche dealer for their oil that is designed of air-cooled motors. It costs a bit more, but helps keep the engine a little cooler and better lubricated than other oils.
2. Check Cooling Fan
Air-cooled engines need air to keep the engine its coolest. Porsche engines use a cooling fan to help keep everything flowing. If you own a 911 then with most models, the fan is easy to spot and check. We recommend turning on the car for a moment and watch to make sure the fan comes on. With it off you may also want to check for any frayed wires and that it moves freely (we recommend disconnecting the battery before doing this check).
If you drive a 356, 912 or 914 then your fan may be under a cover. You’ll have to remove the cover to inspect that the fan is in good working order in a similar fashion as you would on a 911.
1. Check Oil Levels Often
When driving an air-cooled Porsche, one of the biggest dangers that causes overheating is that the oil level is low. In warmer temperatures these cars can burn extra oil and as they age they may develop leaks.
As a safety measure make sure to keep a quart of oil with you at all times. It is also a good idea to check the oil level before each drive to make sure it is filled to the proper level (but not overfilled). And if the oil warning turns on you should find a safe place to pull over and turn off the engine right away.
If you follow these tips then you can enjoy your air-cooled Porsche for years to come, even when it is very hot outside (and yes if you have an air-cooled Volkswagen, these tips are good for you as well).
