Detecting leaks in the evaporator core of your vehicle'south a/c system can exist a challenge. Tucked betwixt the firewall and the dash on the inside of the vehicle, this radiator-like component is located in the plastic evaporator case. The electronic leak detector and refrigerant leak detection dye are the two preferred methods, used by professionals, to detect leaks in the evaporator. This projection is within the abilities of the dwelling house mechanic, simply it does require the use of specialized tools.

Pace 1

Attach the a/c gauge prepare to the vehicles service ports. E'er follow the procedure in the service manual for your specific vehicle. The blue hose of the gauge prepare goes to the low-pressure side service port, and the red hose goes to the high-pressure service port. See the resource section beneath for a link to online service manuals, if you practice not have the service manual for your vehicle.

Step 2

Add together one tin of refrigerant, containing leak detection dye, to the organization with the engine running and the a/c controls in the vehicle ready for "MAX A/C". Information technology is important to add together refrigerant merely through the low-pressure side to avert explosion of the tin can due to high pressure.

Step 3

Test bulldoze for 15 minutes with a/c on "MAX A/C. This will go on the pressures up, circulate the refrigerant dye through the system and help make the leak identifiable.

Stride 4

Cheque the condensation coming out of the condensation tube for traces of the refrigerant dye. As the evaporator leaks, the dye will collect in the evaporator case, and drip out of the condensation tube onto the basis. The condensation tube is located coming out of the firewall, beneath the level of the evaporator case. If in that location is no dye in the condesation coming out of the tube, become to the adjacent step.

Plough engine off and let set for 15 minutes. Equally the evaporator leak refrigerant, it will collect in the evaporator case, and pass into the passenger compartment through the a/c vents on the dash. Exam the vent nearest the evaporator with an electronic leak detector. E'er follow the manufacturer'south directions for using the specific leak detector you take. If the evaporator passes both of these tests, at that place is no leak present, or the leak is besides small to find.
