PostSubject: Dual idler pulley bracket   Dual idler pulley bracket EmptySat Dec 29, 2012 12:16 pm

I have a 95 supercharged Riviera and I have gotten a wealth of information from this site. Unfortunately, I could not find anything about by current problem. The bolt that holds the dual idler pulley to the engine broke off. I have had a couple of mechanics out to look at it and they all said it is not enough room to drill the bolt out and I will have to remove the entire bracket. My first question is, is it difficult to remove the entire bracket? It looks like it runs behind the power steering pump but I am not sure. Is it an easy task or should I hire a mechanic to remove it? Thanks!

Would a right angle drill work to drill a pilot hole in the stub for an ez-out? I don't have a 95 so I don't know.

As for difficulty, we often confuse "tedious" and "time consuming" with "difficult." You might want to look at the R&R instructions in a factory service manual, then decide if it's too much of a job for you.

I would be kind-of wondering why the bolt broke in the first place.

Some of them are reverse thread. I'm thinking someone turned it the wrong way thinking they were loosening it, and it broke off.

I tried a right angle drill but the drill bit is still too long. The bolt is regular thread. I replaced the pulley this past summer and it was regular thread.

I don't have a Series I. I tried to find a picture so I could see the "dual idler" you are talking about. I think it's a tensioner assembly. If I am correct - the thing I would do is just replace the assembly. . You can get one from a parts store or if you're tight on cash, a junkyard. I've replaced mine once, there's stuff to remove to get to it but it's not that big a deal. You can look it up and see pictures on RockAuto.Com and then get it from RockAuto or locally.

You might want to check a service manual concerning the difficulty to remove the bracket. I would call it "time consuming" not difficult. But again, I don't have a Series I, maybe someone else will chime in.

Thanks for the response Albertj but I found out that the series 2 engines do not have the dual idle pulley. Only the series 1. The good thing is our tensioners come off with one bolt!

Okay. I decided to remove the bracket in order to extract the broken bolt. Albertj was dead on. It was a tedious job but not at all difficult. Thanks for the info! I did encounter one problem in the reassembly. The two heater hoses that go into the manifold are leaking coolant now. When I took them off, they just kind of pulled out of their respective holes once I removed the single hold down bolt. When I put them back and tighten the bolt, at least one of them are leaking now. Is there something I am missing? What seals this connection?

Should be O rings. You need to replace them.

Thanks. I'll try that this weekend. I'll just keep topping it off until then.
