Thanks to FOT, a quick job getting a new water (coolant) pump installed within a few days
I had a small leak of coolant, the exact source not known as I began the search. Over a couple of weeks of intermittent flow/drip, some puddles, we found it to be from where the water pump attaches to the engine. I think it explains the loss of small amounts of coolant on several recent trips.
It was speculated to be an o-ring where the pump attaches to the engine and upon removal of the pump that was confirmed.
On the Forum I think it was Pierce suggested to just replace it, cannot take a chance. I proposed that to FOT and they were reluctant given the drips had quit, again. But I figured the labor the same to replace the ring or go with a new pump so as long as we had to take it all apart, let's put in a pump.
Alton said it worked out well to replace it. It is a major task though, 6 hours. Glad there are no longer coolant puddles and worry might damage the engine.
Thanks to FOT for getting us fixed up in short order.
6 HOURS! To R&R a water pump? The big engine in your coach must be arranged
really different than our little C8.3L. I DO admit that I have not replaced our (original) water pump (yet), but It is sitting pretty much completely exposed
right there in the front of the engine. If it took more than a hour to replace our pump I would be really shocked. See below:
C 8.3 Coolant Pump Part # (https://www.foreforums.com/index.php?topic=31729.msg281932#msg281932)
ISM or M-11 water pumps are gear driven. I will look at mine tomorrow and see how long I think it would take me to change it.
^.^d Yep....... must be different, I changed ours last year for the same reason, less than $100 for the pump and about 30 minutes to install. Easiest one that I have ever changed, no radiator to deal with. ;D
On the M-11 it's location next to the frame rail that is the killer. If the engine was in a class 8 truck you could get to it with no problem, tilt the hood and you can walk right up to it. On these coaches you have to work it mostly from under the bottom. Lots harder to get to than on the 8.3 engines.
Did they also put new "O" rings in the oil cooler while they were in the area along with replacing the thermostat and coolant filter?

Include had take off alternator and brackets, add antifreeze. New parts too plus the boot
Maybe I felt too good about this. But one shop would not try it
I just checked mine, until I have to change it no guess on time. Tight area, much to remove. Definitely would do oil cooler o-rings at that point. Almost all the labor would already be done. Hope I don't have to find out the amount of time it takes to do it.
Cman,
I left out the time part in my above post. The 6/8 hours is about right for all that has to be done if you stay at it. At this age with all the aches and pains it will take most of a couple of days for me. This is one job that you don't want to do setting in a campground, pick nick area, or along the side of the road.
@ Mike I think they did you more than fair with the time for all that has to be done.
Mike
Thanks Mike, I felt good until someone said it a quick job, I paid too much. MOT sent me to FOT as they had not done one of these but did see the leak, said needed be done, not ignore.
FOT was great...worked it in, changed it though they thought I might live with it since it had quit for their trial drive. i listened I think it was Pierce, get it done, not wait til on the road. And I drove again for FOT and they could see the leak, up in the engine area...not onto the ground. I bet this explains why I kept losing about 8 oz of coolant on 500 miles, that drip drip leak that evaporated and hard to find until i crawled under with a strong light.
Thanks to Alton and his crew. And MOT sending me there....
I had Cummins do mine a few years ago now and it was 4 hours of labor but they lifted the coach up.
Mike I'm always pretty happy when I can get the service done somewhere other than the side of the road. Price is pretty far down the list compared to a breakdown. Glad you got it figured out.
