Magnuson SC Kit Idles Like Garbage - HELP!

So after the third day. I hear another noise, sounds like a light tapping. I can’t pin point what it is right now. I guess I’ll have to wait till it gets a bit louder. *♂️

Mine sounded like a light tapping and it got louder as time went on (but maxed out after a few weeks) and when the engine was fully heated and on hotter days.

When I first found the issue last September, I'm in AZ, it was loud and then subsided a bit in the Fall/Winter as Magnuson tried to troubleshoot.

When April and May rolled around it sounded like the front end was vibrating off. I was getting looks at stoplights from people, like bro, your truck is going o blow up, lol.
 
Just heard from Magnuson, they are sending me a new tensioner. They claimed there was quite a few that got sent out that were defective. This was mine.

Mine has same #. Does it mean is defective too?

Is it making any noise at all? Any vibrations when fully cranked with the A/C compressor kicks on?

No. Nothing crazy but it has some vibration only when A/C clutch kicks in and last for 2-3 seconds. In gear or while driving nothing at all.

WTF Magnuson :cry2: they look exactly the same, I hope something is different internally in this one. I’ll come back with an update after I’m done replacing my water pump.

What the heck, I hope it works out for you. I wish I knew what tensioner I have then.

Sent email to Magnuson pic of your tensioner was included. Trying to get logical explanation why people are getting different looking tensioner with the same part # . Hope they can clear that for us.

I got a response yesterday from Magnuson over my concern of the tensioner issue. I sent them pics of mine and they are sending me a new one. So it will be interesting to see which one I get.

I will say when I inatalled mine the overall thickness of the tensioner was less. I dont know if uou can see it in the picture but the black arm for the hose support had to be bent a little so that I could get the bolt started. The tension was definitely more than the other one, I used the same breaker bar on both and the new one was much harder to get the belt on.

Maybe we are looking at this all wrong. Maybe I am the one who got the wrong tensioner?
At least yours has a different part number now. Maybe it will be better.

mine has been fantastic since day one, apart from the coolant hose rubbing against the belt and getting cut, but the dealer fixed that. Hopefully they'll figure it out.

this happened to me today too. I was freaking out because coolant was all over the place. What was the fix? If i put it close to one side itll be too close to the fan and if i put it the other side itll be hitting the belt.
