Exclamation unknown leak:mad:

well i have a 1993 lexus ls400 = 135000 miles
i just did a timing belt,water pump,idler pulley change, when i was done i noticed the timing belt was a bit too tight so i drove to Autozone about a mile away to buy a new tensioner.
(i should mention the car has been sitting for 3 weeks)
the car started up rough (old gas) when i got to autozone the car was not overheated but when i drove home it did get (1/4) past the second mark
i parked it
AAAAAAANNNNNNNDDDDD TTTTTHHHHHHHHEEEEEEENNNNNNN!!!!!
then there was a big coolant leak between the engine and transmission coming from the weep hole straight down no oil

any suggestions on what it could be

Sounds like you have a failed water pump install. Did you replace both O-Rings? The tiny one on the water pump & the bigger O-ring on the Thermostat housing?

OP next time please try to have a better thread title.

Better thread titles(more descriptive of the nature of the problem, hoe wit originated,etc make the forum more neat, clean , and a pleasure to search through .

Better titled threads will make for less repeat question postings.

Thanks!
