Description of 🌑️ Enhanced Performance: OTC 7991 Cooling System Pressure Tester Kit for Optimum Cooling Efficiency

OTC's Cooling System Pressure Tester allows you to pressure test the cooling system on most cars, light trucks and SUVs. Also works on motorcycle, ATV, snowmobile, and many marine applications. The tester's universal fit design eliminates the need for multiple adapters. Note: Will not work on Saturns, Kias or Jeeps with a plastic coolant reservoir. Durable blow-molded storage case keeps tools contained and organized so they are ready when you need them.

very simple design and easy to use

very simple design and easy to use. There is an old pump that looks like a new pump. If it lasts as long as my old pump I will be very happy with this purchase. Good price for this tool.

Pros
  • delivery was very fast
Cons
  • quality

Universal tester suitable for diagnostic, test and gauge equipment

OTC 7991 is not as easy to use as typical 'stant' pressure testers and it does not measure radiator caps and the low price eliminates the need for separate adapters . I would recommend it to any technician servicing multiple makes/models.

Pros
  • Good product for its price
Cons
  • 0

Great pressure tester

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…

Pros
  • Handy item
Cons
  • Protection

Typical OTC quality

There is no doubt that OTC products are not the best tools in the world, but they make very good tools at very reasonable prices. The 7991 is no different - it offers professional features at a do-it-yourself price. I'm glad I added this coolant pressure tester to my shelf full of OTC gear 'save my bacon'. ;) The best feature of this tool is the air chamber that isolates the pump from the coolant filler neck. While it's a little tedious to set the bladder at just the right height, it's far less

Pros
  • Lots of positive vibes
Cons
  • No performance
