Hey all, I just picked up a 2000 LeSabre with 253,000 miles on it. I'm needing to replace the belt tensioner (at less than 1k RPM, I have no power steering and am getting temps over 200 degrees). I know that since the coolant lines run THROUGH the tensioner (thanks GM! Stupid engineers...) do I have to drain the coolant to replace the tensioner? Nothing I can find about doing this job seems to say it's necessary.

So, can anybody definitely give me an answer one way or the other? Thanks!

you do realize that if the problem is the pulley is seized you can replace it without replacing the tensioner?
if you do need to replace the whole unit unless you want coolant all over your work area you have to drain it first.

I would atleast drain enough coolant to be below your work area. Best place is to partially remove the lower hose at the radiator instead of the petcock which may snap when you attempt to loosen it. Likely your tensioner doesn't keep enough belt tension due to the weakened spring. I would also change the coolant elbows to the metal ones, if it hasn't been done while you have the system drained.

The metal elbows cost $ 20 or less... So if you have to get them separately just do it.
You can find the elbows in most car parts stores in the help section.

Yeah so the Rockauto got back to me and the ACDelco part includes plastic elbows now - so I'll just buy a cheaper one and get my own elbows separately.
