The Way To Change 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 very much the same for many other Chevy and GMC trucks like the 2500 and 3500.

Changing the AC compressor on a GM 350 motor isn't almost as hard as it seems. The compressor is held for the engine by an aluminum cradle. The cradle does not must be eliminated to replace the compressor. You will find simply just three bolts that maintain the compressor to your cradle that have to get eradicated.

Observe that this process just addresses the bodily swap from the compressor, not he affiliated chores relevant to servicing the AC procedure after a compressor failure.

Start off by eliminating the freon from the procedure. If you want to have it reclaimed, require it to some store that does this.

Remove the 2 electrical connections to the compressor.

Following take away the freon lines type the back again on the compressor. The manifold is held in area by a single bolt. Mine was 15 MM.

Use a pry bar to maneuver the belt tensioner and slide the belt off. I discovered the easiest pulley to get the belt from was the easy idler underneath the compressor.

With all the freon lines away from the way, the bolts are significantly simpler to access. You will discover nuts about the back as well as the bolt heads are held in place by a boss on the front. Mine were 9/16".

Using the nuts taken away  the bolts may be pushed out the entrance. Nonetheless, it seems that they will not obvious the clutch. Nevertheless, there is a flat lower on each and every bolt. Rotate the flat to get next to the clutch plus the bolts will slide out. A pry bar might be applied for getting just a trifle further clearance if your bolt doesn't slide previous effortlessly.

On mine, an individual bolt also interfered with the admirer shroud. I found that by removing the bolts that hold the shroud to the front header, the shroud could possibly be moved enough to get the bolt out.

Using the bolts all out, the compressor merely lifts away from the cradle.

When using the compressor out, I'd to swap a pressure swap that did not come with my substitute compressor. This swap is held in site which has a snap ring.

Before making an attempt to slip the brand new compressor again to the cradle, take some time to tap the bolt hole inserts all the method to the again on the cradle. This can make inserting the brand-new compressor much simplier and easier. They will press again into the accurate site if the nuts are tightened.

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

Reconnect the electrical connections to your compressor.

Secure the supporter shroud.

Make sure the belt is routed properly and utilize a pry bar to move the tensioner and slip the belt back in location.

Add the accurate amount of oil and reattach the freon lines to your compressor.

Now you can have the system serviced and also the freon changed. Resource : Dodge Ram Diesel AC Compressor
