Year: 2004
Make: Honda
Model: Odyssey
Engine Size: 3.5L
Refrigerant Type: 134A
Ambient Temp: 93
Pressure Low: 42
Pressure High: 272
Country of Origin: United States

Has been very hot lately in MO. ( 92-98 and lots of humidity) Odys air has always been more than adequate but lately while still OK, have to use recirc to stay cool, even on long highway trips.

Pressures seem with the realm of OK according to the alldata diy sub that i bought through the link at AMA

There is a fairly low volume squeal when the AC compressor is engaged. I have ordered the belt to replace it. (Runs AC, alternator). I am hoping that this takes care of the squeal problem.

Anything else that I can check out before I get the belt tommorow pm?

If the belt doesn't fix the problem what else an I looking for.

Any help would be appreciated

while you have the belt off, check all the pulleys especially idler pulley and tensioner.. Make sure they spin freely with no rough spots..Hope this helps...

I agree with Chick. The bearings in the idler and tensioner may be squealing,but also, if the tensioner spring is weak, loose belt tension will allow the belt to slip and squeal with the a/c on due to the added load. Higher ambient temps will cause higher pressure in the system increasing the load on the compressor.
