Squeal from fan belt on start.

2012 GU CRD.

Hey all, how hard is it to replace the tensioner (fan belt) on a CRD engine? Mine is starting to give a few seconds of squealing on start up when cold.

Cheers all.

Compress the old one...unbolt, clean gasket faces, fit new one, pull the "hand grenade" pin... Never done it on that engine/vehicle but it's not a massive job if you have spanners.

Have you checked that belt isn't worn beyond spec? that's a cheaper exercise... and a can of "belt grip" spray should see you right for plenty of kilometers...

Heya mate. The job its self is cake. Belt off, Bolt off , bolt on, belt on pretty much. Getting to it is the hardest part. Japanese hands required. Two stubbies worth of a job I reckon.
When I owned a 3L CRD, I replaced 2 in a matter of 6 months. High country water crossings!
The water washes the grease out of it and it begins squealing, eventually seizing if not dealt with.
Tim Bates here speaks of it...

PS. If you go to Patrolapart to pick it up, if you ask nicely, the legends may even fit it for you on the spot. Few minutes work for them. They can probably do it with eyes shut.

I've just ordered the Patrolapart kit. There is a bit of a back story here. About 2 years ago I had the same issue. I took it to my local mechanic and got him to replace the tensioner. Which he did. He said at the time he sourced a non genuine unit as it was cheaper than the OEM part...... So the original tensioner lasted 200k and the after market unit lasted about 30K and two years. I think that a good reason to get genuine parts when possible.

On the bright side. It will make changing the belt tensioner that little bit easier.

Best to come up from underneath to change out belt tensioner_remove lower radiator cowl shroud section first (ie: clips).

Would it be a bad idea to thread a brass barb onto the plastic radiator top thingo?
