Diagnose Car Ac With Gauges вђ Ricks Free Auto Repairођ Essential tools for diy car ac repair. to diagnose and fix car ac problems yourself, you’ll need the following tools: 1) manifold gauge set: you can’t accurately diagnose an ac system using low side pressure readings. manifold gauges are inexpensive to purchase or rent. find a reasonably priced manifold gauge set on amazon . this kit. Here are the tools you’ll need to troubleshoot your car’s ac problems professionally. you’re kidding yourself if you think you can diagnose car ac problems with just the gauge on a diy recharging kit. at the very least, you need to see the high and low side pressures and compare the readings to the outside and center duct temperatures.
Diagnose Car Ac With Gauges вђ Ricks Free Auto Repairођ Understanding normal ac pressure gauge readings learn how to diagnose your car’s ac using pressure gauge readings. you can’t accurately diagnose your car’s ac by using just the low pressure gauge on a recharge kit because you only see pressure on the system’s suction or low side. that’s not enough information to diagnose a problem. Learn about car air conditioning system diagnosis and service, including the use of r134a and r1234yf refrigerants. discover essential tools, step by step instructions for hooking up ac gauges, refrigerant charging, and system evacuation. ensure your car's ac operates efficiently and effectively with regular maintenance tips. Check where the hoses are crimped onto the fittings. check the schrader valves.check for pin holes in the condenser. check where the evaporator drains condensation with uv light. sometimes oil or dye can be seen. note: the dye check will not work if the system is too low and the compressor is not cycling. Step 1: turn the engine off and install the gauge set. step 2: restart the engine and turn on the air conditioning. step 3: observe the pressure readings. though every air conditioning system will vary, you want to see the high side pressure around 20 psi and the low side around 40 psi.

Fluid leaking from car. car defroster not working. my brakes are making noise. windshield washer not working. car shakes when braking. electrical issues after battery change. engine stalling after new battery. smoke coming out of tailpipe. signs of a vacuum leak.
