    once the water pump starts leaking like that you really have no choice but to change it. the longer you leave it the worse the leak will get

If it is just a small hole you can use a steel epoxy on it but you must polished round portion of the hole your going to sealed. but the best is buy new one.

The impeller screws onto the impeller shaft. Go to the site below and you can see a parts diagram. You will select the brand, year, model, etc... It has the part numbers and prices.

There are actually two seals. Are you sure the leak is a bad seal and not the water pump gasket or a cracked/broken housing cover?

Please post a top rating for this solution. Thanks! :)

Water leak


The small hole under the water pump is the weep hole and is designed to start dripping water when your pump has a problem. You should remove the pump and find out what the problem is before it quits and leaves you stranded. Could be simply the seal, or the shaft may have become pitted.

With the brakes, I assume you have looked at the brake pads and they are good so bleeding is definitely the first option. If that does not fix it remove the calipers and check that the pistons move when you squeeze the lever and that you can easily push them back into the caliper (after you disconnect the brake line). Then rebuild them if required and reinstall.
