Leak Problem

[muzziak]

Hey guys, have a 33 gtst with rb25det in there, all the usual bolt on mods that are needed. Got my water pump and timing belt all done about 2-3 months ago because my water pump was on its way, and since then have had no dramas. However last night on the drive on, temps went over 100 degrees and when I opened the engine bay coolant absolute EVERYWHERE. Figured that once the car warms up and the thermo opens, there isn't a leak, it's literally like a tap has opened and whatever's in the system just pours out. Checked hoses, despite being old are not cracked, it seems to be coming from the bottom of the water pump, but it's been recently changed so I have no idea.

Any ideas ? Thanks in advance

If it seems to be coming from the bottom of the water pump, then that's where it IS coming from and you had best pull the timing cover off and have a look see. Options are cracked pump, blown out gasket or totally rooted shaft seal. All of which require you to have the pump off.

Yeah nah.

Check everywhere but the spot can actually see water leaking from.

Have you never had a new thing fail?

And also, what are the usual mods needed, and how was the old pump on its way?

I'm a curious guy?

I assumed it was coming from the pump, just wanted to grab a second opinion on how often new pumps decide to fail. Old pump was leaking, got it pressure tested and that was the issue, so it was changed.

Thank you

Hmm old pump was leaking... New pump is apparantly leaking... Nah it couldnt be that... Must something else.
