coolant leak after replacing upstream o2??

[browningcrew24]

So I replaced my up stream o2 sensor this morning on my 97 3.4 v6 and then took it for a drive for a few miles....I parked it in the garage for about an hour to go get showered and ready and when I was cleaning up the shop I noticed a pretty good leak under the cat area and its deff coolant...it was coming off the trans pan too and a couple other places. Is there any thing I could f'd up down there that would cause a leak?? Gets worse after driving...

Probably hit the rear heater lines. They run along the passenger side.

do a search for 'coolant leak';

you are not supposed to have coolant coming out your exhaust --- if that is what is happening (no pics)


paste this into google:

i second you messed up your rear heater lines.

checked heater lines and they actually looked pretty good....been driving around all day and no more leaking since that one time this morning...will still keep my eye on it and see if I cant find the spot its leaking if/when it starts up again..thanks I know how search but basically every thread has its own solution and I figured why not ask and see what people had to say today...sorry to waste your time.

It was the TB coolant hoses! When I took the IAC off that same morning to clean it trying to solve rough idle problem one of the coolant hoses clamp did get put back on.....
