Review on 🌡️ Enhanced Performance: OTC 7991 Cooling System Pressure Tester Kit for Optimum Cooling Efficiency by Kev Mills

Have used this pressure tester on 4 different cars so far and it has done the job every time. I used it to find a very small leak in the lower radiator hose and also a small leak due to a bad thermostat gasket which I would never find with the engine running because it would burn the block but not enough to stop the leak see . I used it on Nissan but not for 3 adapters. The only thing I noticed that could be improved is the strength of the metal spring clips that grip the radiator neck. When tightening the gray handle on top, one of the clamps sometimes slips off the radiator neck. Just pull this part as far as you can and slowly inflate your bladder if this happens to you and it should seal snugly. Or, tighten as usual while holding the clamps and have someone pump your bladder. Once the bladder is inflated it holds up and the product works great. Yes I would buy it again or recommend it to a friend it's a good product.
