hatcity Posted June 15, 2011 Share Posted June 15, 2011 Have a "metallic" sound coming from front of engine (2001 E-7 427) Have no other symptoms such as leaking, temp. variations.Can only listen for it but not putting hands ears near to feel. Doesn't sound like belt squeal either. Any other options?looks like a pretty straight forward change. Plan on replacing belt at the same time. Any thing else?Thanks, Ed Quote Success is only a stones throw away.................................................................for a Palestinian Link to comment https://www.bigmacktrucks.com/topic/19402-is-it-water-pump-time/ Share on other sites More sharing options...

shortstack Posted June 15, 2011 Share Posted June 15, 2011 The belts would be my first suggestion too. Check for a rough bearing. Fan, alternator? Good luck.

rhasler Posted June 15, 2011 Share Posted June 15, 2011 Check the belt tensioner and make sure the belt isn't tracking off of the roller. The mark on the roller shouldn't be much wider than the width of the belt. Might check the alternator and make sure nothings getting into the fan on it.

fjh Posted June 15, 2011 Share Posted June 15, 2011 pull your belts and run it some.[/quote} I'd be doing this first! nail it down first! A Metallic sound ???? Is It a churp or a scraping a rattle?Bad lifter will make a Metallic chirping sound. Fan hub or water pump is possible. Take the belts off! and run it as Glen stated Quote Link to comment https://www.bigmacktrucks.com/topic/19402-is-it-water-pump-time/#findComment-79731 Share on other sites More sharing options...
mowerman Posted June 15, 2011 Share Posted June 15, 2011 just shoot a little wd40 on the inside of belts,while its running,sound should quit immediately,if thats the problem,,but mack pumps do go out,from time,to time,its not an unusual problem...good luck...bob 1 Quote Link to comment https://www.bigmacktrucks.com/topic/19402-is-it-water-pump-time/#findComment-79736 Share on other sites More sharing options...
hatcity Posted June 16, 2011 Author Share Posted June 16, 2011 Appreciate the advice. Will have to check all these areas Sunday, as I have work scheduled thru Sat.The "metallic" sound is like metal grinding.First though, I have to disconnect the air line to the fan. Broke today. I can just bend it over and put a cable tie on it. Fan has always run continuous. No problem here in 90 degrees.Again, thanks.

hatcity Posted June 26, 2011 Author Share Posted June 26, 2011 UPDATE- Not having a Snap-On brand $300 special tool for this, my son helped me with it. He has smaller hands that were able to get a ratchet in there. Released tension and spun different pulleys. Changed belt as we were able to reach in.SOUND IS GONE. Thanks all for different ideas. Now I can return the water pump, git ma money back.

Mike Posted June 26, 2011 Share Posted June 26, 2011 Don't need it now.Save the $$$ for tires If it had been me.....I would have saved the money to pay for fuel and had to wait for the tires. That is the luck I have. mike Quote Link to comment https://www.bigmacktrucks.com/topic/19402-is-it-water-pump-time/#findComment-80420 Share on other sites More sharing options...
rhasler Posted June 26, 2011 Share Posted June 26, 2011 I've always used a standard flex handle ratchet on the E-Techs except for those in mixers. For the ASET AC and for mixers I use a ratcheting box wrench slid over the bit on a stubby 8mm Allen socket. It's just short enough to get in between the radiator shroud and the tensioner. The MP engines are a different story altogether... 1 Quote "Mebbe I'm too ugly and stupid to give up!"

I always try and hold my mouth right, it seems to help me with about everything I do. And if I get something that is really difficult, I have to use my tongue and squint my eyes. Hey Hey, when I know no one is present, i'll sometimes say words I haven't never heard before. ta hee mike Quote Link to comment https://www.bigmacktrucks.com/topic/19402-is-it-water-pump-time/#findComment-80435 Share on other sites More sharing options...
