High Head pressure in my AC compressor on my 2000 Dodge Caravan

I have a 3.0 V6. The compressor seems to build up head pressure and the belt slips on the compressor pulley. The compressor and Dryer are brand new.

Try the "h" valve or expansion valve. It's known to stick.. Write back if you have more.

I would install guages and get a visual on the high side reading...you may be faced with a plugged reciever drier which is full of dessicant beads that can cause a restriction...air flow through condenser is critical as well

Could be what heavymetal77 said, or simply a loose belt.

How to replace the belt on 2000 dodge caravan


I had to replace the brushes on my 2000 Caravan alternator so I had to remove the serpentine belt. I was able to remove the belt by prying the idler pulley inwards to take of the pressure and slip it off so I think you should be able to do the same thing.

2001 DODGE GRAND CARAVAN 3.3; AC DOES NOT WORK. AC COMPRESSOR REPLACE 3 TIMES, BUT IT BUILDS UP TOO MUCH PRESSURE, RELEASES THRU THE BACK OF COMPRESSOR.


Then there was no reason to replace the compressor
unless it broke down & spread debris into the system
Just poor or no diagnosing of the issue
You have high side pressures that caused the valve to release
Need to study why it happens & where the system blockage is
Did the first compressor burn up & trash the system?
If so then any competant shop know all the componets have
to come out & be flushed or maybe replaced
I would say you have a $1500 job just for starters to redo the
job correctly now 3 compressors went on for no reason

i think you need a new compressor which is why the belt was left off ,also the gas is the main lubricant for the compressor as well so running it with no gas hasnt helped either ,best of british with it anyway

1996 dodge caravan cuts out and dies, then my air went out when the belt pully thing broke. got that fixed but my van is still dieing when the air is on. what could it be.


Have the ac system checked,if the high side pressure is getting too high,it will try and lock up,this would cause the problem,also make sure the condenser cooling fans are coming on when the ac is turned on,if they are not,then a relay,or high side pressure switch is bad,on the high side ac line coming out of the compressor.

I have a 2000 Dodge Caravan 3.0 V-6 and my problem is tha t after the AC compressor was recharged, the engine developed a knock at low RPM's. We replaced the the rod bearings in the engine and I still have...


From what I understand, and I also have a 2000 Caravan with the 3.0 V6 is that this is a common noise the engine makes and just part of operation of the engine. Some people have told me if you run Pennzoil motor oil it will help, in that Pennzoil has paraffin as one of the lubricating additives and it supposedly quiets the ticking in the engine. I don't run it up here in the North Country because paraffin can build up inside the valve covers and cause operational issues in the winter. However, if you are in a warmer climate and don't use it currently, try an oil change switch to Pennzoil and see if it helps.

2000 Dodge Grand Caravan AC blows warm


If the compressor is running and you have the same temp on both tubes the compressor is probably shot. You need to check the pressure on the high side too. It should be around 200.

When you replace the compressor, make sure you also replace the accumulator, orifice filter and flush out the evaporator and condenser. The only moving parts on the ac system is the compressor and often when it fails it will put small metal particles into the a/c system that will cause your new one to fail.

Hope this helps.

AC clutch slipping on 2000 dodge caravan . How can I resolve this


If the a/c clutch is slipping it will need to be replaced. If it is slipping because the compressor is siezed it will need a new compressor, clutch, expansion valve, orings, system flush, perhaps a new condenser or more. However, Dodge has a recall for the compressors failing. Call your local Dodge dealer and ask about that recall. If it applies it should be free.
