Last night I noticed a grumble like a hungry bear coming from the engine on tick over. It went away when I revved the engine.
Today I found a bit of play in the water pump, I could slightly rock the fan. Taking off the fan belt the noise disappeared when the engine was ticking over.
AHA! I thought, new water pump required, but it has no signs of leaking coolant and I cannot make it grumble by hand turning. I then span the alternator by hand, no play but a definite faint grumble.
So what I have is everything working fine, a slight bit of play in the water pump, and a faint grumble from the alternator.
Reassemble fan/belt/shroud, and wait to see which fails first? Turn up the radio?
Or has anyone had a similar noise/problem.
