One additional comment on Step 5 of the procedure: Follow the heater pipe along the engine block to locate the bolt that fastens the pipe to the engine block. I believe the clarification will help the do-it-yourselfers like me.
Replace a water pump on your 240 series Volvo
(This was done on a 1982, 244GLE B21)
If your water pump starts to become noisy or you notice excessive movement of the shaft or if your pump starts leaking, it will be time to replace your pump.
Last week I was in the process of replacing the water pump in my '91 240 Volvo when I coincidentally came across your article on changing the water pump on the website, and found it a good source of reference. The good news is: I have successfully replaced the water pump; and the interesting news is: it took me three days to finish the job. I certainly do not want to discourage anyone from attempting the task, it was really quite straight forward had it not been for the mistake I made. I would like to offer the following experience to preclude others from repeating my mistake: [links]

One of the nuts holding the pump in place is located in the timing belt housing, and you would need to remove the upper shroud of the housing to access it. As Murphy Law would have it, I dropped the nut into the timing belt housing as it was being backed out. It took me the next couple of evenings to fish out the nut from the otherwise enclosed housing. To avoid disassembling the timing belt housing, I had resorted to cutting a small hole through the plastic shroud at the bottom of the assembly to retrieve the nut. One needs simply put a piece of cloth or any material underneath stud and nut in question to catch it when it comes loose to avoid the extra challenge. [links]
The hard water pipes that fit to the water pump and wrap around the back of the engines on B230 models are a common problem for leakages. The problem lies in the fact that the mild steel pipes have a tendency to rot out - especially where they fit to the back of the water pump. We've sold replacement water pipes for this application for years to address this but customers that live in harsher climates may end back up in the same situation in a few years time. To combat this, STS Machining right here in Oregon has designed a replacement water pipe for these models made from stainless steel to make it the last water pipe your Volvo will ever need!

This is the time of year I always get a few cold leaks. Usually tightening hose clamps takes care of most or them.
I believe it happens because cold temperatures cause metal to contract (so coolant pipes get slightly smaller) but at the same time cause rubber to expand (so they create a gap between pipe and hose).
If the leak is bad enough? Do you have coolant settle at bottom of oil when cracking the drain plug?[links]
[Editor] At conversion, consider adding both a variable orifice tube and an in-line filter in the compressor suction line (both described below) to your system to improve low-end cooling and protect the compressor against any system debris. more
