Review on GearWrench 3289 Oil Pressure Tester by Jason Dahlkemper

Revainrating 5 out of 5

Remove the check valve in the adapter fitting. Type Tire valve core

Works well. However, there is a learning curve, so to speak. Found it out the hard way. There is a check valve in the fitting on the adapter that measures the oil pressure on the pressure gauge. This only resulted in peak pressure readings, which in turn resulted in a missed live pressure diagnosis. I removed the valve and everything is fine.

Pros
  • Oil pressure gauge tool
Cons
  • Defects present
