The plastic pulley has already started eating itself on the belt. The whole assembly is getting replaced under warrantyI think that these sealed bearing idler and tensioner pulleys are not as long lasting as used to be . If possible I usually lift the seal and put a bit more decent grease in there .....but its pointless if you damage the seal .![]()

I can adjust all those setting on my wife’s Cadillac.That's about 5C. which to me is way too Early. Cadillac doesn't, or didn't provide a way to adjust the Temp, only on or off. Even when it was -30c a couple of Months ago, I was turning the Wheel and Seat Heaters off in less than 3 minutes
I can adjust the Level of Heat when it is on, but I can't adjust the Temp at which it turns On, which is about 10C(50F)I can adjust all those setting on my wife’s Cadillac.
Yes ,I have to replace the serpentine belt on my car and ordered new idlers and they are steel with a bearing . Only want to replace belt (100k+kms) but I am doing the idlers and waterpump as well coz they are a proper pain to get at .I have found that the old fashioned metal idler pulleys last about 100k miles and are pretty cheap to replace. I usually replace the belt & pulleys at the same time.
Yeah ,My idler is coming up on 250,000 miles. Current belt has about 80,000 miles. The first one didn’t look too bad at 168,000 which is when the intake manifold failed. 2008 F150.
The bearings wear but also the friction surfaces that the belt rides on wear as well. Yep I'd prefer to do the whole thing in one job, not to replace the belt and then a month later hear the tensioner/idler start to make noise. Last time I did it was at approx 105,000 miles now I'm at 184,000 miles. 1998 Jeep 4.0. The one on my 2007 Grand Cherokee 5.7 is at about 135,000 miles and still quiet.Yes ,I have to replace the serpentine belt on my car and ordered new idlers and they are steel with a bearing .

I got lucky. I have the 4.6 liter. It’s easier to work on than the bigger motor and has always done what I asked of it… even when it shouldn’t have.Yeah ,I have one of them plastic intakes ....with variable intake runners , I cant wait for that to crap out
.
I found out that it has to come off to get at the rear spark plugs .
I have been told that water pumps are prone to failure ( Toyota 2gr-fe) so I figured Id fix it before it broke . Apparently I have to remove the whole right side wheel and strut assy to get the water pump out![]()
