Re: Behaving intermittently

3. My first thought is to use a garden hose and mist the condenser (keep misting it) and check your vent temps and skinny/fat line temps and report back I also agree with above. Seems like an issue of improper condensing, likely due to bad electric fan(s) or bad fan clutch or debris covering conden...

Re: 1234yf operating pressures

At ambient temperatures above 100°F (like it was in Phoenix recently) That was wintertime. 110 plus has been our norm lately. Currently, my AC is out in my home/office. :( Heat is no laughing matter; Phoenix hit 119F several times so far this summer, and folks and animals have died from the heat.

Re: 1234yf operating pressures

He said he had a 1234yf recovery machine, so I assume he can add specified amount of 1234yf automatically.

Re: Can I drive on the highway without a condenser fan?

I assume that the part you wish to drive 2K miles for is NOT for the fan for the 2003 Honda???

By the way: folks do add aftermarket fans to their vehicles, I'm not sure why a mechanic or you couldn't add a complete new fan and control to your Honda.

Re: 1988 Mazda B2200 Evaporator

Those aluminum evaporator cores are just fine. I would definitely not tear apart a working system to swap out one of those. My own practice, with more than AC: "Never trouble trouble until trouble troubles you" I tell folks that if their AC and heat keep you comfortable, then there is no ...

1988 Mazda B2200 Evaporator

In August 2002, I developed a pinhole in the center of the evaporator on my 1988 Mazda B2200, confirmed that with soap bubbles. With 2 kids and money tighter back then, I bought a new serpentine-type copper and brass evaporator, drove to Arizona Mobile Air on W. Clarendon as it was in-stock and less...

I think you made the logical choice.

For that area, you can test for leaks with soap bubbles.

Re: Dumb question-Will larger condenser improve performance

Disclaimer: I'm NOT a professional AC mechanic, I'm a retired industrial chemist. But I know some, and have lived in Phoenix 5 decades, but now split my time between Phoenix and Prescott area. 109F ambient is common for summer in Phoenix, today and tomorrow are forecast for 115F, but cooler than the...

Re: What's causing o-ring leaks on my '04 Frontier?

Cusser , my Frontier is also a 2.4L with about 110K miles on it. I'm in central South Carolina, so it's hot - but not AZ hot. It looks like your fan clutches have failed on both of yours, and I'm curious how you diagnosed them? I've spent more time than I'd like to admit watching youtube videos and...

Re: What's causing o-ring leaks on my '04 Frontier?

I found one post somewhere where someone blamed blown o-rings on his Frontier on high head pressure caused by a bad fan clutch, but the truck itself is cooling fine. Yes, the coolant temperature can still be fine with a bad fan clutch; a properly operating fan clutch definitely helps an AC system. ...
