AC Compressor Identification

Awesome! I believe I have a Denso, but I'll have to check again tomorrow. If it is then its on to testing for leaks and the clutch.. Hopefully convert it to R134A.

Keihin (throw it away)



Denso (keep it around)



Denso (also good)



Basically, the Keihin has big ugly blocks all around it.

So I normally jsut throw the A/C out, but I decided after 50+ days in a row over 100 degrees it's time to have A/C in the DD. My question I have the second Denso comp that came with the car, and I purchased a new version of the first Denso comp. If I find the top plate that bolts on from the junkyard, do I also need to purchase the line, or can I use the ones that came with the car?

im not too sure if the top manifold is interchangeable, from what i could find the compressor is slightly bigger than the other denso

I know the top is not interchangeable, but I was wondering if the hoses need to be changed. After doing some junk yard diving, I determined you do NOT need to change the hoses if you switch out denso Compressors.

The bottom pic is Denso 10PA15E - considered by some to be the better unit. The middle pic is a Denso 10P15 or 10P15E - They have a habit of blowing one of the four o-rings that seal to the four ports shown, possibly due to a manifold design that has only 3 bolts to hold it on (one of the pictured bolt holes is not used as there is no cooresponding bolt hole in the manifold). Its manifold is in two pieces and requires an extra seal that is not in the Santech MT2561 kit. It is in Santech MT0453. I got mine from AutoZone. Due to seal differences I would say the manifolds are not interchangable, but other threads have said the hoses are as long as both compressors are Densos.

Oh and (you will see this elsewhere too) be sure to replace your receiver-dryer - it doesnt cost too much and is critical to getting a reliable and well performing repaired AC - epecially if it has been inoperative for more than a season. If you see ANYTHING insde your lines or hoses other than light green (dye tint) oil, a flush becomes required rather than a good idea...

I also found a collection of rubber plugs handy to keep the crud out while working. AC internals are almost as, if not even more, sensitive to dirt and contamination than wheel bearings or crankshaft bearings..
