A/c hose removal consequences

Hey guys,

I will be removing my main a/c hose on my 88 190e for replacement. I just wanted to ask if i have to worry about the oil in the compressor, or if this is just a nice easy swap. It got crimped when i pulled out my engine.

I will replace the orings on the compressor manifold.

Thanks for any comments.

There are some guidelines on how much oil to add to the different parts based on full capacity rating. You are going to replace the dryer aren't you?

I had a manual laying around here somewhere that had the various capacities of different cars or you can try You will want to add a percentage of total to the various parts that you replace, remove, etc...

If it were me I would flush everything out and start from scratch.

I would love to be able to replace the dryer, however since just replacing the engine and its associated costs, i now have $1.13 in my account. No kidding either. Due to my buget of 0, i can only due what i already the parts to do. So i guess i will try to find if i need to add anything due to the replacement of that hose. Engatwork, thanks for the website reference, i will search to try and find some info there.

I did that job on my old '86 190E 2.3. No fun. Jack the car up high and use good jackstands. You will have to loosen a few things to get it out. Don't forget the fuel cooler circuit. Release the presure and cap the lines while they are disconnected. Seems I had to raise the engine slightly. I had to replace the compressor too, so while I had everything out of the way, I replaced the motor mount. To finally get the line in or out, you have to kinda screw it into position. Twisting it in from the top as I recall. Suddenly it all falls into place. Plug the ports in the compressor when you take the main fitting off and oil loss will be minimal. Cap/plug the hoses and all fittings if you are not going to replace the dryer. Want to keep exposure to moisture to a minimum. I converted to 134A when I did the job and also replaced the TXV and receiver/dryer. Cools well, but that darn 134a will find some place to slowly leak out. I replaced just about every O-ring and it still needs to be topped up each season. May be leaking thru the hoses themselves since they are not barrier hose.
