Review on Motorad MT 300 Pressure Tester by Patrick Burns

Revain claimed it would fit my car when it didn't. I tried to research and test this before buying but there is no information to make this possible. There is no mention of the need for an adapter, and I couldn't find any information about the adapter when I specifically searched for one. I know the inside diameter and depth of the radiator cap, but the manufacturer of this product does not provide any information for comparison. The manual that comes with the pressure tester contains a list of possible adapters. Instead of actual sizes, they use vague terms like small neck or flat small neck. Toyota is not on the list. If so, I wouldn't be sure if it's the right adapter. There are 5 possible adapters only for GM, 3 for VW. An adapter costs almost as much as the entire pump set. It may be the best product in the world, but it's useless if customers aren't given the information they need to use it. I am sending back the one I received. It's useless. By the way. The diameter of the rubber piece on the pump adapter is 38 mm.
