heater hose bolts into tensioner ?? Help
ok looking around for leaks I notice that where the heater hoses go into the tensioner there is a single bolt that hold them in...this bolt has a gap under the head and looks like its not tightened down...however it IS tight...but its a weird 10mm shoulder type bolt that almost looks like its not ment to be tight....so you can wiggle the connection around by hand the way it is..
I was going to put a washer on the bolt but I dont think it was ment to have one or they would have used a straight non shoulder bolt....but dont know for sure...
Any of you guys noticed this ??

Is this the 3.3 or 3.8 motor? I've read where there'* a plastic[?] heater hose pipe going into that mess that'* notorious for leaking. They make a metal replacement to fix it right, o-ring is the culprit.

If you do a image search on bing there'* a lot of exploded views of tensioner setups and some use washers some don't. It would help if the exact motor and year was searched.

Apparently, it doesn't need to be.....those o-rings do the job.....only time I have ever seen them leak, was because the hoses were removed, while replacing the tensioner assembly, and the o-rings weren't replaced....

O-rings are your friends, and bad things happen when you neglect your friends.
I've only had to take heater hoses off to replace a tensioner, so I've gotten a new set of O-rings each time. But yes, the bolts are more of a guide, to make sure you've squeezed, forced, and struggled to get the hoses far enough onto the tensioner.
