There are aftermarket radiator caps that increase that pressure even higher, although the added pressure may cause additional stress on other components that weren’t designed to handle the pressure, such as gaskets, hoses and clamps.īuy a testing kit that is rated for at least the same pressure as that listed on your radiator cap. Your typical cooling system is under 10 to 20 psi of pressure. Kits come with different pressure ratings. With a variety of options and price points, there’s a number of features you should look for when shopping for a tester kit. Since many of them look virtually identical at first glance, this is an easy way to make sure you’re using the right one for the right vehicle. For example, some models include color coded radiator test caps, with each color corresponding to an automotive brand. Some of the manufacturers go above and beyond to make their kits as easy and accessible as possible.

Some kits are geared toward specific makes, while others include adapters for almost every major car brand on the market.Īnother factor to bear in mind is ease-of-use, especially if you’re not a professional mechanic.
When buying a tester kit, one of the first questions you need to consider is whether you will be buying the kit for a single vehicle, or whether you plan on using it on several different makes and models. This allows your engine to run at the temperature it needs to in order to operate efficiently, without boiling the coolant. The coolant system is pressurized, which raises the boiling point of the coolant. The radiator acts as a heat exchanger, cooling the coolant as air flows over it before the coolant goes back through the engine to absorb more heat. To understand what to look for in a tester kit, it’s important to understand how your automobile’s cooling system works.Īs coolant makes its way through your engine, it absorbs heat the engine generates. Engine coolant is made from a 50/50 mixture of antifreeze and distilled water.
