New to Nico, KADE problems. W/pics

Here is a short rundown of the situation. I drive a 93 240sx Coupe. (BTW)

Around a month ago I drove to work, everything was normal until I came out of work 9 hours later only to find a huge puddle of coolant in front of my car. (I was parked on an incline.)

So I did my research and came down to the conclusion that it was the water pump so I replaced my thermostat and my water pump.

Everything was cool, bled the system and was good to go no more leaking and what not for around a week.

So yesterday I was pulling into my driveway and my girlfriend asked me when I got out why was there fluid pissing out under my car again.

So I lifted the hood and low and behold it was leaking pretty profusely from the same spot again.

Could be a random coolant hose under the intake manifold, possibly do a pressure test or just feel all the hoses to see if one has a tear.

All of the signs seem to point to the water pump, after I replaced it with the auotpwn special it stopped leaking for a week then started back again.

Alright, disregard the photos as it looks to be coming from BEHIND the thermostat housing and accumulating by those bolts.

Any ideas?

Alright, disregard the photos

Yeah, I was going to say, those bolts are for the lower timing cover and really don't hold any coolant behind them... just oil.

You said the leaking stopped after the WP/thermostat job... maybe you just had a gasket failure there, and need to go through it and do it again. Did you wait for a sufficient amount of time for any RTV to cure before driving/pressurizing the system?

[John P]

I let the RTV cure for about two days, as I was busy with work.

Figure out which one is leaking by putting your finger underneath each one of the gasket surfaces... if its leaking from there, there will be a drop or so of coolant clinging to the metal, and your finger will come out wet.
