Water pump leaks on 1989 Supra turbo

[Monkey123]

My first post, thanks in advance for any advice. I have a 1989 Toyota Supra Turbo with Targa top. I changed timing belt timing belt tensioner, crankshaft seals, camshaft seals, and water pump of last year in June. I don't use the car much and it is kept in the garage. Now the car is leaking a small amount of cooling at the water pump. I forgot to pay attention when taken out the water pump. There are long and short bolts. Does anybody have a diagram or drawing of the bolt pattern. By the way, the water pump was brought at Autozone.

Is the leak coming from the gasket surface, or the weep hole?
And yes as Bill noted there are different sized bolts.
Where ever you buy the water pump, just make sure its ASIN brand.

Have the same problem bought water pump from lordco gasket it came with was a really thin paper gasket so I ordered a new one from toyota. I was told it's a thick rubber gasket.

Sure its not a hose making the waterpump look like its leaking?

The bolts should only be able to go in there spots. Small bolts may or may not even touch the threads for the large bolts and the large bolts will bottom out before they are tightening against the water pump.

You can rent a pressure tester at autozone. You pay a depsot and they give it back when you return the tool.

Checked with the car running definitely coming from the water pump all along the bottom of the pump. I saved that image you posted showing which bolt goes where but I was paying close attention to the lengths when I removed them.

make sure it isnt a crack that was caused from the flimsy housing
