DieselPig Posted August 30, 2020 Share Posted August 30, 2020 Just changed the timing belt, water pump on my Fiesta, with new tensioner & idler wheel. Car starts OK but there is now a whine when off the throttle in gear. Stripped it down again and the tensioner had moved slightly. When I torqued up the bolt I noticed it moved so I set it off centre and when I tightened it up it was bang in the middle. Still makes a whine! Any ideas what next?

TomsFocus Posted August 31, 2020 Share Posted August 31, 2020 Have you tried with the aux belt off? Might be aux related, especially if you fitted a new aux belt. When I did mine, the extra tension of the new belt wrecked the aux tensioner! Quote Link to comment Share on other sites More sharing options...
DieselPig Posted August 31, 2020 Author Share Posted August 31, 2020 Did think that as I have replaced all. Just stripped it all down again, tensioner in correct position but there appears to be black gunge in the grooves on the timing belt. All the pulleys are clean so not sure what it is, it wipes off easily. Is the belt defective? Its a Dayco 941048 and there web catalogue give the correct type.

TomsFocus Posted August 31, 2020 Share Posted August 31, 2020 Hmm, I'm not sure what's going on there. Definitely no oil, diesel or coolant misting around the belt run at all? Quote Link to comment Share on other sites More sharing options...
DieselPig Posted August 31, 2020 Author Share Posted August 31, 2020 No leaks and its clean under the covers. New belt felt waxy so maybe a coating of something? I washed all the pulleys with brake cleaner before fitting the belt. Just re-assembled it all and the new tensioner would not work as expected. So I've put the old one back in (bearing is fine) tensioned OK and run the engine without the accessory belt & tensioner. Sounds lovely!! 🤩 1 Quote Link to comment Share on other sites More sharing options...
DieselPig Posted August 31, 2020 Author Share Posted August 31, 2020 Fitted new tensioner for accessory belt and its whining again! Will run it for a few days and see if it settles. Quote Link to comment Share on other sites More sharing options...
DieselPig Posted September 18, 2020 Author Share Posted September 18, 2020 OK have sorted the problem and this may help somebody else with a 2011 1.6 TDCi TZJA engine. Middle of the year the timing belt tensioner was changed (don't ask me why ask Ford!) what the difference is? Possibly the spring tension. Continental do a complete water pump/timing/tensioner kit and list two different types based on year, according to ETIS my car was built in June so I assumed the engine was assembled in May, the tensioner was changed in July so for my car the correct kit is CT1162WP2. For vehicles manufactured after July the Continental kit is CT1162WP4. Quote Link to comment Share on other sites More sharing options...
