First time ever I've heard of a 240 Volvo needing water pump lubricant. And I've changed a lot of water pumps on these 240s.

Without much work at all, you might be sure it is not the typical belt squeak from cold alternator trying to recover a battery after starting: Remove the B* wire from the alternator terminal. Protect it from touching anything. Test drive.

Though don't take what I write here to heart. As this is the work of an incompetent:



Indeed, I titled the BrickPix (Photobucket SUCKS) exhibit "Water Pump Replacement by an Incompetent."

Of the dozens of Volvo RWD and other auto makes water pumps I've replaced, the most recent is the first real screw up on my part in 34 years?

Now while the water pump is installed with yet another new Volvo gasket and Volvo seals, well, we have slow coolant loss and not exterior to the engine on the 1990 Volvo 240 "li'l red" Wagon.

So, if squeaking, it means one or both of the sealed bearings have extreme wear, of it is a cheap pump, or well, who knows. Water pump lube probably does nothing as these are sealed bearings. Unless the seal is lost, or the factory lube grease pack spent.

Check the water pump lower weep hole for any coolant signs.

A wiggle of the water pump fan blade with the pulley belts slackened may reveal some play. The fan clutch bearing may also seem to have play. Lest you have the solid fan with no clutch.

Welp, there you go.

Unless it is leaking, I do not understand how a lubricant will get into the bearing.

Unless this is a joke, I think that you are silly not to install a new pump.

I have read posts where the water pump has taken the radiator with it. I have also read posts where a belt has taken the timing belt with it.

Unlikely the lube travelled from the expansion tank to the engine. Drain enough out of the rad to allow you to dump the contents of the expansion tank into the rad and see if that helps.
