How To Substitute the AC Compressor on the GMC 1500

I these days swapped the AC compressor on my 1995 GMC K1500 Suburban. The compressor and treatment are exactly the same for lots of other Chevy and GMC trucks together with the 2500 and 3500.

Changing the AC compressor on the GM 350 motor just isn't almost as hard as it appears. The compressor is held for the motor by an aluminum cradle. The cradle does not have to be eradicated to replace the compressor. You will find only three bolts that maintain the compressor to your cradle which have to get taken out.

Notice that this process only addresses the bodily swap with the compressor, not he connected tasks relevant to servicing the AC process following a compressor failure.

Start by eliminating the freon in the process. If you want to have it reclaimed, acquire it to some store that does this.

Remove the two electrical connections into the compressor.

Up coming take away the freon lines sort the back again from the compressor. The manifold is held in location by a single bolt. Mine was 15 MM.

Utilize a pry bar to maneuver the belt tensioner and slide the belt off. I found the simplest pulley to get the belt from was the clean idler underneath the compressor.

Using the freon lines outside of the way, the bolts are a great deal easier to accessibility. You can find nuts over the back as well as the bolt heads are held in site by a boss to the front. Mine had been 9/16".

Along with the nuts taken away  the bolts could be pushed out the front. Nonetheless, it appears that they will not obvious the clutch. However, there's a flat reduce on just about every bolt. Rotate the flat for being near the clutch plus the bolts will slide out. A pry bar might be employed to have just a little further clearance if your bolt doesn't slide previous simply.

On mine, one bolt also interfered together with the supporter shroud. I found that by removing the bolts that keep the shroud for the entrance header, the shroud could possibly be moved sufficient to obtain the bolt out.

Along with the bolts all out, the compressor basically lifts from the cradle.

When using the compressor out, I'd to swap a stress switch that did not include my substitute compressor. This swap is held in place which has a snap ring.

Before attempting to slide the completely new compressor again into the cradle, take time to tap the bolt hole inserts all the method to the back again of the cradle. This could make inserting the brand-new compressor considerably simpler. They will press back into the accurate location once the nuts are tightened.

Slide the bolts back again in by once more aligning the flat place on each bolt with the clutch and slide it in. Place the nuts on each individual bolt and tighten.

Reconnect the electrical connections towards the compressor.

Safe the enthusiast shroud.

Be sure the belt is routed accurately and utilize a pry bar to move the tensioner and slip the belt back again in place.

Add the appropriate  quantity of oil and reattach the freon lines towards the compressor.

Now you can have the program serviced as well as freon changed. Resource : Chevrolet Silverado AC Compressor
