T5 Starter motor

1996 850 T5 Estate (198000 miles !)

I have posted a sort of question on this before, but after some experiments, I think I need to replace the starter motor

Starts no problem first thing in the morning and after several hours standing
intermittent but pretty frequent problem, turn the key, might fire up after a short-ish stop, but more often a sort of wheezing, a clunk or even a half hearted attempt to fire. Usually does after about 4-8 minutes approx.

I have changed the fuel pump relay which I first suspected but I am more drawn now to a failing Starter. Are there any other check before doing this?the cables to battery etc seem to be in good order

Apart from a noisy alternator, a new MoT last week all is still great

Is the battery in good condition?

If it is sounds like a loose electrical connection or bath earth point somewhere

Battery is 2 years old and in good condition, will check connections and earths, thanks for that, I have a planned pcv change to do, so that would be a good time to change the starter if necessary as access is improved, but a fail(ing) motor wouldn't allow cold starting?

If your battery connections are crimped ones like my V70, check they have not loosened and dropping voltage.
You'll know as they will get warm.
I ended up soldering both my cars +ve terminals and it showed up worst when warm as the alternator charging current had heated the well up.
