2000 Chevrolet Tracker Parts Questions & Experts Answers

• Q: How to replace the A/C Expansion Valve on 2000 Chevrolet Tracker?

  A: Discard and recover the refrigerant as the first step before changing the thermal expansion valve. Reverse counterclockwise motion on the expansion valve plate while removing the bolt enables separations of the evaporator inlet and outlet tubes from the expansion valve. The next step involves taking out the expansion valve from the evaporator by removing its 2 bolts then discarding the O-rings. The installation process requires mineral base 525 viscosity refrigerant oil for coating new O-rings that need to be positioned onto the evaporator. Position the expansion valve to its place on the evaporator before tightening the system with 2 bolts. Reinsert evaporator tubes to expansion valve before you turn the plate clockwise and lock the bolt at 35 N.m (26 lb ft). Operation of the A/C system with refrigerant leak inspection concludes the procedures by evacuating and recharging the refrigerant.
