Clarke, if you add an overflow tank that will fill your radiator whenever it burps out the air. Just have to keep the overflow tank full. After a few miles it should be filled.

Forest, did you do like Richard and convert a bug sprayer pump bottle for use as an overflow tank? I actually have two of them, and really don't need two.

I can confirm that the overflow tank can deal with air trapped during a refill of coolant, I did not vent the engine. I had to add coolant to that tank following the first few times the engine ran after the refill. It didn't take more than a quart or so each time.

Leave it to an engineer to come up with that idea!
No, I bought a plastic tank and a weld on hose fitting from USplastics.com
I used a heat gun to weld the fitting on, and drilled a hole in the cap for the overflow hose from the radiator. The fitting I welded on is for the run over if the tank is overfilled. Probably don't need that, just need a way for the extra to run out.
I guess anything would work for getting the air out. If you just run the overflow hose from the radiator cap into a bucket with coolant and let the engine idle any air should burp out then when the engine cools off it should draw coolant back into the radiator.
With my engine I was adding coolant after each trip, with the overflow tank I haven't added coolant since I added the tank.

I haven't really had to add coolant in a couple of years, so I'm not sure if I really need the overflow tank. Until the pump failed I hadn't seen the coolant level below the looking glass in a couple of years.

Hopefully Richard will chime in, I usually just wait. Check the top of the Housing for the Thermostat, there may be a Petcock there, if so that would be a place to start.

There are at least two petcock valves in the area of the water pump that I can see. Just got notice from UPS that the pump has arrived in Tyler (1am last night) and is out on the truck for delivery as of 4:05am, so should have the pump sometime today and will begin the R&R process. Removed the rest of the old coolant yesterday afternoon. I have 12 gallons of Power Cool sitting in my trailer along with 12 gallons of distilled water ready to go in as soon as I can get the new pump installed.

After all the discussions on leaking water pumps, I decided to check mine again. It was a year ago when I first noticed the problem in Vegas & replaced the upper hose & no leaks. I just finished up putting air bags in the front yesterday.
.......................IT'S LEAKING AGAIN..........................
Planned on leaving for the left coast Tuesday, so we will see !!!!!!!!!!!!!!!!!!!!!!!!!!
Having a water pump flown in Monday

UPS came through yesterday with the delivery of our replacement pump around Noon. I immediately started to remove the failed pump by first removing the fuel filter that is mounted on the side of the pump to give better access to the 5 different hose connections, and the three 5/8" bolts that hold the pump in place. The easy part was getting the 3 bolts removed......and I thought that would be the hard part....haha! Getting at the screws that hold each hose in place was the difficult part, but using the method patients and gently massaging of the parts it came lose.....well, I had to cut one hose connection.....the bottom one that is about 4" long. I ran over to Napa and got a replacement cut in just a few minutes, so it was worth it, because by cutting that connection the pump then came free and it was just a matter of maneuvering it out. Then I had to remove to plumbing type fixtures from the old pump to transfer to the new pump, as well as remove two plugs from the new pump where these two fittings would be installed. This proved to be the most difficult part of the process, but, again using patience and proper leverage, as well as my old trusty Black and Decker Workmate bench as a vice I succeeded in removing the fittings without damaging them, and installing them on the new pump with a liberal amount of pipe dope. At that point it was around 4pm, and I was thinking I would be happy if that was as far as I got, but I decided to see if I could at least get the pump back into place, and finish it up today (Saturday). As it turned out I was able to get the pump bolted back in place, and all but one hose reconnected as the sun set. I have one more hose connection to secure, plus torque the 5/8" bolts using the chart Steve Ward provided, plus re-install the fuel filter, and then add 23 gallons of Power Cool.

One pleasant discovery was that I apparently have just enough of the proper tools for this kind of job......I did wish I had a little larger pipe wrench, but by adding a pipe to the end of the wrench for extended leverage I was able to break the fittings loose. I sprayed white lithium grease in the channel on the engine side of the pump to help hold the "O" ring in place, and also on the inside of the hoses to help slip them back in place more easily...worked like a charm.

Of course the final test is turning over the engine and hoping there are no leaks. If there are leaks then it will take a little more patience and massaging, but I know I'll get there eventually. It has been nice not have have any time pressures this week as I waited for the delivery from California. I would not have had that luxury had this happened in the vast spaces of West Texas...I would have been at the mercy of someone else's time frame, and pricing for a replacement pump.

As it turns out the bearings on the old pump appear to be fine, so the core would appear to be a candidate for re-manufacture. I'll check into the cost to do that, and if it is reasonable then I'll have a spare pump for the future, although, if the new one lasts 30 years like the first one, then I may not live long enough to use it.

All in all it sounds like a good day. Next time use a little dish soap on the hoses.

Finished buttoning up everything this morning and began to refill the radiator. After every 2 gallons I would look inside the driver's side engine bay door to see if anything was leaking. At about the 10 gallon mark I began to see a lot of leaking.....uuggghhh!! Couldn't tell where it was coming from, so I drained all 10 gallons back out and began unbuttoning everything so I could get an idea where the leak was coming from. After a couple of hours I determined that the leak was coming from the top hose above the water pump. On the side away from view the hose had not quite seated when I re-installed the new pump. I didn't want to remove the whole pump to get at that hose so I spent a couple of hours "massaging" the 4 inch connector hose down far enough to seat it with the hose clamp. I re-buttoned everything up and used my 8mm fitting with a ratchet to tighten down all the hose clamps TIGHT! Put the 10 gallons back in and saw a small trickle coming from the top hose, so I continued to tighten both clamps until it stopped. I have topped off the radiator and still NO leaking! I will recheck coolant level in the morning to see if it has settled anymore, and add as necessary. Then I will start up the 6V92 and see what happens. Long day of putting my body in awkward positions....going to grill some steaks and drink some Margaritas......

Checked the coolant level this morning, and no change. Fired up the 6V92 and it purrrrred to life....no leaks. Ran until it came up close to operating temperature....didn't want to disturb the neighbors tooo much this morning. But I am very happy that all has turned out well....we arrived here last Sunday with our tails between our legs.....AGAIN....but have successfuly negotiated another mechanical fix.

Drove down to Austin, TX today and arrived around 4pm. The trip was without incident, and there were no mechanical failures while parking either! The first 20 minutes my eyes were riveted on the temp gauge looking for any sign of a problem. I began to relax after that and just enjoyed the drive along secondary roads (155 to 79 to 84 to I-35 south). I really love Texas secondary roads! This will be my last post on the 6V92 water pump issue as it appears to be resolved. Thanks again to Tom for helping me find the replacement pump on Ebay.

Clark,

I have a Newell acquaintance who travels the back roads instead of the interstates, he loves it. He tries to stay on US highways because most of them have a good paved shoulder and many are four lane (especially in Texas).

I have done that a few times and sometimes you run thru neat little towns that have some beautiful old buildings, brick streets etc. When the weather is right, it is fun to stop and walk around and go into some of the shops. It is amazing what you can find; some junk and some not! It makes for some good memories.

Tuga, you are right about the shoulders and many have 4 lanes.....and little traffic!!! On the way back from the Austin rally Tom and I drove secondary roads all day the first day over to I-10. What a fun trip, and there were a number of cool towns we passed through that I would have liked to explore. We did stop at one town for a Mexican lunch, and it was amazing!
