td5 engine more power when cold

[ben]

i have a TD5 90 01 plate 85k that seems to lack power when the engine has warmed up.

when its cold you feel a real pick up in power when you use the fun pedal and it pulls well up hills but when its up to temperature it doesn't have that get up and go about it

any ideas would be great

Try disconecting the MAF,

As a side, you don't really want to be using your right foot hard until the engine has warmed up anyway.

But agree with Andy, try disconnecting the MAF for a cheap/easy test.

Also have a look at the viscous fan, maybe it's free when cold but sticking on when hot? Mine does roar and give a noticeable difference in power when it's operating. It does feel more sluggish. You'll probably hear it roaring at lower speeds though...

yeah i don't hammer it when it when she is cold but little things like towing when you first set off she pulls away much better. when I've done a long run say on the motorway and come off at a junction when i pull away again i can hear the fan spinning is that the viscous fan you mentioned.

Yeah, I'd say that's the fan you can hear. If you stand in front of the truck you'll feel it as well as hear it - they shift a LOT of air!
