    AC question

    Ok. It looks like we're going to have to purchase the other condenser. Thanks for your help.

    AC question

    It came with a kit from RockAuto, and the description said that it fit the truck. There's an inline orifice tube that can be cut into the line between the receiver drier and the compressor...

    AC question

    Yes. The old condenser had the orifice tube coming out of the bottom of the condenser to the evaporator. The new parallel condenser that came with the kit doesn't have room for the orifice tube. On our truck, the receiver drier is between the evaporator and the compressor.

    AC question

    We have the same condenser that you have. Where is your orifice tube installed?

    AC question

    The saga continues. We purchased the switches and wired them according to TBI’s instructions. With the parallel flow condenser, the only place that the orifice tube would fit is between the compressor and the condenser. We vacuumed down the system and checked for leaks, all good. Then we began...

    Thanks. I did order the low pressure switch that is for the R134a conversion.

    RedHead Steeering Gears.....

    I have only heard good things RedHead. Their prices are a bit steep, but I personally would spend a bit more for quality, especially considering the problem seems persistent.

    1997 C3500 belltech 3" drop spindles, ongoing brake issues.

    My daughter also had a poor experience with Belltech. She has a 1990 GMC 1500 with drop spindles installed by the original owner probably in the early 90's. While driving home from work one day, the front end started shaking, so she pulled over as the front end dropped to the ground. The...

    AC question

    Sweet! It does make sense now. I have ordered the switch you mentioned. The local parts houses didn't have any in stock. We'll probably get back to it in a couple of weeks, when my daughter isn't working overtime. The only difference that I can see with her truck and yours is the location...

    AC question

    Here’s the heat/ac controls. To duplicate your install, I need a switch with the pressure range you stated. I hate to ask PWT, but can you sketch a quick drawing showing the switches in series? I would appreciate it. Thanks.

    Ahhh. The clouds are clearing. Thanks.

    AC question

    Is the low pressure switch that you refer to the one on the receiver dryer? I couldn't tell from the picture.

    AC question

    Thanks for the reply. The existing orifice tube was installed on the liquid line at the condenser, so that's where we were going to install it on the new setup. Is this not correct? The white switch on the left looks like the old one; although, it was green in color. I had assumed that the...

    AC question

    First time poster. This looks like a great site. My daughter has a 1990 GMC Sierra 1500 shortbed, with the 5.7. We have done quite a bit of maintenance and enjoy working on the truck together (I have a garage with lots of tools). Our latest project is converting the AC to R134a. We...
