OT post a/c question

Use a variable orifice tube:

Recharge it with R134A. I've done so many and I don't know what the hype is a bout, but if you change the dehydrator for one with the proper desiccant in it. The cooling difference isn't that noticeable!

Just my two cents!

PS You can also put an electric cooling fan to push in front of the condenser for help with the extra high side temperature and pressure.

TY for your reply, forgot to ask should I put oil in compressor too or just the 134-a system has not been open since change over was low on freon last winter so i just unpluged compressor as it was cycling.

Speaking of which, my old girl has been overheating lately with the A/C on.

If it was in fact a proper change over:

I would evacuate it, with a recovery machine! Then the recovery machine will capture any amount of oil lost during the vacuumed cycle, which will be measured for you. You replace that amount with PAG then add the R-134A as per the original label specifications.

Most customers think I'm looking for an extra dollar:

But the difference in high side pressures and temperature is enough to call for a secondary fan. A single 1400 CFM fan, wired into the relay, to just run when the ac is on will work great Doc.

I have a 25,000# GVW AT cooler mounted up front which roughly covers 1/2 of the condensor, so a single fan would probably be my best best as I would have to relocate the AT cooler even further upwards (don't feel like making another set of brackets). I was thinking of even running it off of a rocker switch mounted to my dash so I can just pop it on when I'm stuck in traffic.

Ty you all for the responses. I got a new 4 core rad. in the old girl so I dont it'll overheat

That will do fine;

There was a company that had dual 1700 CFM Fans, now that would blow the nuts off of the condenser, and whoever was standing in it's way!

LOL
