Make sure that when you get any diesel repairs done to your vehicle or equipment, they come with diagnostics tests so that the technicians are able to see if there are any clogs in your filters or other parts of the system. Having someone check all of these components out at once will ensure that you don't have to keep paying for more maintenance work for things that could have been addressed during your last visit to the repair shop. When the engine has completely cooled off, get a radiator cap tester and put it on top of your radiator. This nifty device will allow you to pressurize your entire system, which will check a few different problems for you. If you don’t own one, don’t worry, most part stores like AutoZone will let you rent one for free.
