antifreeze leak :(

[evoracer200586]

I filled up my radiator with antifreeze, and started the car. Then i notisted a little bit of antifreeze on the ground. It looks like its driping out where the belts are. Do you think its a crack in the block? or a bad gasket or what?

There is a small weep hole in the water pump pulley shaft. It lets you know when the bearings are starting to wear out. There is also a water pump gasket there, and a few coolant lines on that side of the engine. Check the lines, then check the water pump pulley area. If necessary, use a bit of UV dye to track the leak origin.

Or buy or rent a cooling system pressure tester to see where it squirts out.

Blown water pump seal. Replace the timing belts while you're there.

Alright guys thanks, im going to check those out

yeah I just bought a new water pump...

Better buy the new timing belt, tensioners, etc while you are at it.

And be careful to not put the water pump pulley on backwards.

Also: One common source of a water pump leak is the o-ring not installed properly. You must replace the o-ring in the crossover inlet pipe by putting it on the pipe end first, coating with coolant, and then insert pipe with o-ring into water pump – do not put the o-ring into water pump first as it will not seat properly and will leak.

make sure you go to satan and buy your o ring there. dont go to an auto parts store!!! i kept leaking at the water pipe o ring after i put my head back on because the o rings i got were to thin. i even tried using rtv also and it still would leak. i went to mitsu and bought an oem o-ring, slide it over the water pipe end FIRST then slide it in to the water pump. The o ring satan sold me actually made a "popping" sound like it locked into place when i put it in. the kragen one just went in and out really easy. $3.06 for a stock oring and it stopped my leak, it was noticably thicker also. just FYi
