ecotec 2.0, alternator belt adjustment
blakep82 - 9/2/08 at 05:23 PM

afternoon

looking at my engine which will be sent away son to be stripped down and put back together,

I don't need power steering or air conditioning, so all that gubbins is coming off.

the belt adjuster is next to the power steering pump, not on the alternator where i'd have expected it to be.

looking from the front, from left to right, we have the alternator pulley, crank pulley, tensioner, power steering pump pulley.

so without the power steering pump, the tensioner is useless.

does anyone know where i can get a kit to use the alternator to adjust the tension?

cant you fabricate something? The bottom mount will keep the alternator ridgid, make a braket with an elongated for the top of the alternator? Seems pretty simple unless im missing something?

i think i may have missed something lol
i found this kit for the xe engine


appear the ecotec already has the bottom mounting, so all i really need is the rod ends with the theaded tube for adjustment. wonder if they sell the seperately

Hi Blakey.

We have done just this in the past. I take it you mean that the belt tensioner is the sprung type on the big power steering pump bracket??

If so, there should be a strap bolting the alternator to the inlet manifold, plus a bracket where the "adjuster" would normally go on the alternator, plus a conventional "pivot bolt" on the bottom of the alternator.

If so, remove the strap, slot out the bracket or weld a slotted bit on after cutting it down, then just find a shorter multivee type belt to drive it, job done.

That's what we've done on my brother's manta that's running one of the very late 8 valve vauxhall engines with the late type front end as per ecotec.

just read your other post.

I moved the alternator to the passenger side on my locost, and made a rose jointed rod like that fpr adjustment.

A couple of cheap joints from mcGill motorsport plus a couple of threaded sleeves, one rh one lh thread, weld em together with a big nut in the middle to turn it all with, job done.

Think McGill do the threaded inserts, if not the randall motorsport certainly do, saves buying a lh thread tap.
