Questions & Answers

Which model (diameter size) item will fit our 1998 Olds Silhouette van's air conditioning lines?

End 1 (in) of the Fitting Size: 5/16"

For a 2006 Lexus GX470, what size rear ac lines do I need?

The discharge line is 10 mm in diameter; I'm not sure about the suction line, but I believe it is 16 mm (5/8) in diameter.

I'm trying to block off the rear evaporator on a 2005 Dodge Grand Caravan. What size is this?

Measure the OD (outside diameter) of the lines with a micrometer. It's possible that the two OD lines (in and out) aren't the same.

It's very simple

5/5

My 12' E350 van's rear AC was blocked off with these. I found the split in the line and cut the lines with a lo profile pipe cutter within 12" of the T, then sanded them smooth. Before cutting the lines, I had a local shop evacuate the A/C system and perform a vacuum test before repressurizing it. Since then, the air conditioner has been blasting icy cold! This blocker has made me very happy. Thread locker was used on the threads, and PAG 46 refrigerant oil was used to lubricate the o-ring. To ensure a perfect fit, use rings. Torque wrenches were also used to ensure that the bolts were not overtightened. Getting the proper diameter fitting was the most difficult part. I suggest cutting the lines as close as possible to the T joint. According to what I've read, if you cut at the vehicle's base, the compressor oil will pool there and eventually burn out the compressor.

As vehicles get older, the cost of "non-essential" repairs rises

5/5

Convenience items that are "essential. " As vehicles get older, the cost of "non-essential" repairs rises. Our willingness to "invest" in our old clunker often outweighs our need for "essential" convenience items. Dorman's problem solvers make repairing air conditioning systems in vans and SUVs a lot less expensive. You have the option of removing the rear air conditioning system or repairing it with a Dorman line splice. Thanks to Amazon for making these available at such a low price!.

During the installation process, the brass fitting cracked

3/5

Unfortunately, the brass fitting cracked while I was attempting to connect it to the refrigerant line, leaving me unable to complete the job with the remaining parts. Maybe it was just a bad brass item I got.

It's simple to use (but you'll need a torque wrench)

5/5

It's simple to use (but you'll need a torque wrench). I finally got rid of my leaking rear air conditioning, and now I'm at least getting some cold air up front!.
