the little factory hole that is next to the coolant drain bolt, what makes coolant drip out of there. i am replacing the entire waterpump, but i'm curious to way it started dripping?

 

I think its a bad seal but im not 100% positive.

 

it was most likely the mechanical seal . it is usally the firstto let coolant threw then goes out from there [<u>DONT FORGET THE BOLT THAT HOLDS THE IMPELLER ON IS LEFT HANDED THREADS !!!!!</u> make sure you also put a new bolt seal washer on it .

 

Its called a weep hole. It is there to let you know when the seal goes bad. Your seal has gone bad. Id suggest replacement.

 

thanks, the mech seal was cracked, just wanted to know exactly why it drips. thanks everybody!!

 

If the seal was cracked and not worn; this is sometimes an indication of interrupted flow to the pump (producing heat).....and then thermal shock to the seal itself when coolant is re-introduced.

 

ah, don't say that.

 

I am trying to get this mechanical seal for my uncles 87 however the suzuki dealer says this part is discontinued any suggestions?

 

Grainger and a few other places are now selling mechanical seals (most are minimum 5/8" shaft, unfortunately); yet not sure what type you've got.

You'll need a shaft diameter and seat O.D. (along with a seat cross-section diameter if this is a typical type 21 mechanical seal) to check around.

 

You can get the whole repair kit on ebay for $26. He has 85-86 and 87-92 kits.
