VEVOR 14-Piece Radiator Pressure Tester Kit: features and specs

The VEVOR radiator pressure tester kit is a set of tools for checking a vehicle's cooling system for leaks. A hand pump puts the system under pressure through the radiator or coolant reservoir opening, and a gauge shows whether that pressure holds. VEVOR lists it for cars, motorcycles and trucks, and packs everything into one carry case.

What a cooling system pressure test does

A vehicle's cooling system runs under pressure, which raises the boiling point of the coolant. A leak in a hose, the radiator, the water pump seal or the cap shows up when the system cannot hold pressure. By pumping the system up to a known level, typically close to the figure printed on the radiator cap, you can watch the gauge for a drop and look for drips. It is a common first step when coolant level keeps falling for no obvious reason.

What is in the 14 pieces

According to VEVOR, the kit contains a manual pressure pump, a thermometer, four metal adapters and eight colour-coded test caps. The pump is made of aluminium with dual rubber rings at the hose connection, which VEVOR says gives good airtightness. Its testing range is 0-35 psi (roughly 0-2.4 bar).

Colour-coded adapters

The main difficulty with testing different vehicles is that filler necks and caps come in many shapes. The kit handles that with adapters in different sizes, each matched to a colour and a number. The same numbers appear on the adapters and on the case, so you can identify and return each piece. VEVOR says the set covers a wide range of Japanese, European and American models, but the listing doesn't give a model-by-model list.

The cap adapters combine aluminium plates and steel with rubber seals. The rubber is what makes the seal against the filler neck, so it is worth checking it for wear over time.

Storage and portability

The case measures about 13.4 x 3.7 x 11.4 inches (34 x 9 x 29 cm). Shaped slots hold each piece in place, which keeps the set organised in a garage or the boot of a car.

Using it sensibly

The general advice for any cooling system test is to work on a cold engine, because hot coolant under pressure can cause serious scalds. Never pump beyond the pressure your vehicle's manual specifies. Follow the vehicle manual and the kit's instructions for the correct procedure.

What to check before you buy

• Fit: compare your vehicle's filler neck or reservoir with the adapter set. Some vehicles need particular adapters.
• Pressure range: confirm the system pressure of your vehicle is within the 0-35 psi range.
• Vehicle type: the listing mentions cars, motorcycles and trucks; check your specific model.
• Seals: rubber parts wear, so inspect them before each use.
• Experience: a pressure test shows that a leak exists, not always where it is, so you may still need to inspect hoses and fittings.
• What's in the box: pump, thermometer, adapters, test caps and case.
