How is alternator/steering pump belt tightened on 92 Stealth

ref CG 140 102 145 952
Daniel,   sound bite not available, BUT...
1. Oil pressure OK, so it is not a main.
2. I don’ think it is a rod either, I have heard a rod knock years ago. Noise is apparent at both ends of the engine.
3. Steering works ok, and no water leak at water pump. I noticed the noise AFTER the car overheated due to loss of coolant. I may have a leaky heater core, as I seem to loose coolant, but can not find any liquid. (occasional steam on windshield)
4. I am going to remove the alternator/steering pump belt, and start engine to see if noise continues.  If it does, I suspect water pump, as it is driven by timing belt. (Thanks to you)   If not, then I’ll change power steer pump.
All alternatives are a challenge considering space and my age (74).  It appears to me that alternator belt is removed by loosening bolts on alternator and then pivoting the alternator to loosen the belt. The belt idler does not appear to rotate to loosen belt. Getting under the car is difficult. Changing water pump seems more difficult than changing steering pump.

I appreciate any further comments you may have on the noise, on changing either pump, and alternator belt. (Belt needs replacing anyway)

Thank you very much....Ray Webber
