Antifreeze coming out of weep hole after changing thermostat

Postby j.maclean » Mon Aug 23, 2010 8:59 pm



Hey everyone, I just replaced a thermostat and did a coolant flush on a 84 Aspencade, previous to doing this I didn't have any noticeable leaks but tonight after having it out for the first run after doing this I am dripping antifreeze from what looks to be the weep hole on the water pump, it only drips while running and appears to stop when shut off. Is it possible to have a bit leak out of the weep hole after thermostat/coolant flush?? Or would the water pump need replacing? Thanks for any input!

You could have had a failing water pump already, and the leak was blocked with sludge. Now that you've flushed the sludge away, it's free to leak. It could be just a seal, but if you are going to pull it all apart to replace the seals, you might as well do the pump anyway, because you will have to do it eventually anyway - and really, that's not one I'd want to do twice. :)

Make sure you use Honds Coolant.All other coolants have silica in them and that will cause a leak.

Not all other coolants - as long as the coolant says that it is silicate free, it should be OK:

That said, I use Honda coolant. The water pump/cooling system on Goldwings is somewhat delicate, and seems to like Honda coolant.
