 Topic: Bewildered, bedazzled and befuddled! Boiling WD
Posted: 20 Jan 2012 at 7:02pm |
|
My TlW loader has a WD motor in it. After the motor runs a few minutes, the temperature gauge begins to move to normal temperature and then to hot. At that point, the radiator boils over. Thinking that it still has an old thermostat in it, I checked and the thermostat had been removed. Here's what I know: (1) The coolant level is full when it boils over, (2) the fan belt is tight, (3) when filling with coolant it guzzled it ran into the system as fast as I poured it in, (4) when the motor is running, it does not appear as though coolant is circulating in the top of the radiator, and (5) the water pump does not leak and turns freely. Removing the radiator from this outfit is a major task so I would to that as a last resort. Any ideas on what is wrong? Thanks.

It is plugged... your rad, might just be slush if its cold and your antifreeze is weak.

"it does not appear as though coolant is circulating in the top of the radiator"
--- if the radiator is not plugged, then the water pump is not pumping.. you should see some movement, especially with no thermostat in it- water should POUR back into the upper hose to the radiator.

Is this new to you? If so, perhaps the impeller of the water pump is worn off. Or, re-direct the hoses so that you can pour water into the top engine hose and compare what comes out the bottom (can close off the bottom hose). Then do same with radiator - how much water does it hold compared to what it is supposed to hold? I do not know what a TIW loader is, so I don't know how hard it is to do this. Obvioulsy, need to be careful (antifreeze mix) if the weather is too cold!
If you have had it a while, did this happen suddenly? Mabe impeller broke off.

Sounds like the water pump gave up the ship! You may need a new pump there Farrell. We have em' in stock if it turns out ya need one..

The problem arose last summer and the coolant level was low. However, filling it to the top did not solve the problem. Thanks for suggestions on checking the radiator flow. The motor and radiator are all new to me so I have not had experience with them before. Can an impeller go south and have the pump not leak?

Absolutely. My WC's impeller was shot. Didn't leak a drop!

Sounds pretty serious to me, should I drive out there and take it off your hands?

I need to tear into a 301 that is doing the same thing. Top of engine would be hot but not radiator. Thermostat, water pump, piece of shop rag lodged somewhere?

Lonnie, It could be pretty cheap right now. These things are absolute beasts to fix anything.

With the impeller pressed on the shaft, it can split. I had a '68 F350 that would overheat about ten miles from home, (big block, supposed 390 4 barrel carb with a 5.13 rear axle). When i took the fan belt off, I could spin the water pump shaft with my fingers and it would coast at least half a turn. Not loaded by water or seal, though it wasn't leaking. I didn't open it up because that killed the core value. With a new pump I could run it as far as I could afford gas, about 9 mpg loaded or empty if I kept it under 60. Dually.

Yes, if the timing is off it will run warm to a little hot, but if timing was that far off he would be complaining about how it runs also.

Thanks to all of you for your responses. After sorting through everything and thinking about the problem some more , I think that it is a broken impeller in the water pump. I must admit that a "toasted" impeller would not have been on my hypothesis list. Given the way fluids have moved through the radiator and block, I don't think there is a blockage. However, after the pump is off, I will test for flows as some of you have suggested. Timing is not an issue as it runs too well to be out of time. Cheers to you! It is nice to have a team of experts so willing to assist. Many thanks.

Farrell, It seems you have solved your problem. Just be sure the water is flowing through the block.
We had a B whose block was full of mud. They had a leaky radiator and could not fix it quickly so they were putting in stream water when needed. Trouble was the stream water had settlement in it and it plugged the block.
Good Luck!

If you pull the top radiator hose off and crank over the motor, water should shoot out the hose... with no thermostat installed.

Yea, sounds like bad water pump. Ive had impellers come loosw and spin of the shaft resulting in no coolant flow. Had it hppen on an engie Id overhauled, took a while to get it thru my head the remanufactured water pump had a slipping impeller. Good luck.
