Question about 2003 Chevrolet Suburban 1500

2 Answers

Same noise 2003 Chevy Suburban A/C noise upon accel. As per first write up, my 03 makes a severe "clacking" noise upon acceleration. Once crusing, it goes away. I've tried turning off the AC and the noise goes away or does not start if system is turned off. Since it only seems to make noise in the acceleration phase (high RPM) and not in the steady cruise phase and cooling is not affected, would this be a "clutch" impending failure vice a compressor decline. I have the tools and semi-knowledge to fix either, but can not identify "type" of compressor on the car. Looking up clutches seems impossible. Thanks for the help in advance.

    Thanks for the info. On the 28th of June, I did exactly what you just suggested. I went to the pros and had the system evacuated. I took the entire AC system appart, flushed it to the extreme, repalced with a new compressor, reciever dryer and orifice tube - total parts cost $315.00. I then had the pros evacuate (a 2d time)and recharge the system again. My AC now works great and with no noise. My research found that the "clattering" noise was indeed the compressor (Denso) which had shed an internal valve/flap (apparently a very common problem). This causes the internals in the compreesor to bind up (spin erratically) which causes the belt tensioner to "chatter" away like a playing card in bike spokes going 100mph. The belt will ultimately break or come off, and in the Suburban, often break or severe the transmission cooling lines. I think eventually the compressor would have really tanked. None the less, the estimate to do the same fix here in central Texas was in the $2500.00 arena. Ultimately with parts, evacuation x 2 and a recharge, some fairly easy labor and a lot of cuss'n, I did it for under $400.00. By the by, to buy the AC clutch would have been in excess of $350.00 and would not have solved the problem - I think. Hope this helps others out there.

Just change the compressor it is easier than changing the clutch if you do dont forget to change the reciever dryer and the orfice tube and have a evacuation done on it.

Same problem here. I can make the flapping sound go away for about 10 minutes by spraying water onto my condenser coil. A/C is blowing cold air which tells me freon is making the circuit. Flapping is between 1500-2000 rpm.
I am thinking somehow the fan clutch for the radiator isn't working well enough when it gets hot(when I spray water on the condenser the noise stops and it continues to blow cold air). Someone else try this to verifi if its an isolated case(me).

I have a clacking noise upon acceleration or neutral idle. It appears to be coming from the transmission. What could be causing this?

I would check your flywheel rise the front of the suburban to get under it make sure for safty you put jack stands under it where the engine oil pan meets the transmission there is a cover you can remove there is four bolts that hold it on with a flash light look at the center of the fly wheel the crank might look like dirt markings if it is the transmission need to come out to replace the fly wheel too much to explain how to remove the flywheel it would be better to take it to a garrage or a transmission shop

Suburban makes a clacking sound when accelerated and ac is on. When you shut ac off the sound stops. I replaced the tensioner pully this morning and it is still making the same sound

sounds like the clutch on the front of the a/c compressor unless the actual a/c compressor is locking up and causing the belt to slap.
the clutch would make a rattle like noise.
