How to Add Refrigerant to a 1998 Chevrolet Express 3500 6.5L V8 Turbo Diesel Standard Cargo Van (3 Door)

When the air conditioner in your 1998 Chevrolet Express 3500 starts blowing hot air, you likely have a freon leak. Recharging the freon in your AC system is an inexpensive and easy first step to restoring the cooling capacity of your A/C system. Most refrigerants include a leak sealer that will seal small leaks in addition to filling the R134a freon. The A/C system in your Express 3500 consists of a compressor that is belt-driven, an evaporator and freon. If there is a problem with your compressor or evaporator, adding freon will not restore cooling.

How do you recharge AC in a 1998 Chevrolet Express 3500? The low side AC port location is the first thing to find when you are looking for how to put freon in a car. Once you find the 1998 Express 3500 AC low pressure port cap, hook up the can of refrigerant to the low pressure port. When your compressor kicks on, add freon to the correct pressure. In addition to cooling, freon lubricates the compressor when it runs. Typically the AC recharge kit you buy will have enough capacity to add enough freon to get the AC in your Express 3500 to blow cold air.
