Cool Need your help/advise

Questions to the forum;

What happens to the thermostat or water pump if left for a day or two with out coolant/fluid?

Last night in order to get more room to work in my car (95 E320 63 K miles) I disconnected the water hose from the top of radiator to thermostat, and one other hose, with the loss of some coolant. I will not finish the job which involves changing the belt, belt tensioner, and tensioning shock for two more days. A friend suggested that I should change the thermostat because he felt that they are not supposed to be without fluid for more than an hour. Is that true?

In the same vein, I manage to take off the belt, belt tensioner and shock without taking the fan off, I do not have one of those especial tools that grasp the back of the fan pulley. Is there another way/technique to take the fan/fan clutch with out this tool?

I was worry enough last night that this morning I called Phil (from Fast Lane) and ordered a new thermostat it should be at my house by tomorrow I hope.

I would like to hear your comments and suggestions in these two things.

Many thanks in advance

That's gotta be a first. Leave them dry as long as you want. You won't damage them in any way.

Thanks Sixto, your comment was reassuring I was not sure what to think. Earlier today I had spoken to Phil (from Fast Lane) and he was not concern either, I guess the paranoid part on me took over.

Today I got to work and mention to one of my coworkers who happen to have been in one of his previous life’s a Volvo mechanic about the coolant lost and my concern for the thermostat and he said that it was best to changed the thermostat because in his experience once the thermostat gets dry they tend to sized/get stuck? Well, the rest is history I called Phil and ordered a new thermostat just in case.

It turn out that the fan belt on my car was so loose that I was able to simply pull it of from one of the top pulley’s and the rest just came off very easy. The belt was in sad shape with many cracks, it needed to be changed. I then proceeded to take off two other pulleys and two hoses to gain access to the belt tensioner, the belt tensioner shock, and the long adjusting screw. I was able to take off all of these with out major problems except for screw that holds the bottom of the shock in place which was hard to reach. I did all of this with the fan still in place because I could not figure out how to take off the viscous fan clutch without the “special tool”.

Tonight I got home and decided to try the advice of one of the forum members who had suggested to just leave the viscous fan clutch in place and to just simply remove the fan (which I did) by simply removing the three Allen screws. Tomorrow I plan to continue this odyssey (Homer will be proud of me) by bolting the new parts in place after I give a good cleaning to the front of the engine, is pretty dirty/ gluey at the moment and since I have most things off why not.

It's rare that a belt gets loose even when it's very old and very worn. My money says that your tensioner is worn and the new belt will be loose no matter how much you bear down on the tensioner. 63K miles is pretty low. M103/4 tensioners are usually good for 100-150K miles.
