Hi all!

Bring the car I purchased yesterday at home !
I noticed that passenger side floor was wet!

Already got some advices telling me that it could be the heater core!

Here's a pic from the engine.
It's a 1969 Cutlass Supreme Holiday Coupe V8 350. Car has AC, but AC compressor has been removed!

Here's what I noticed (sorry for bad quality pic):
-Red arrow: Hose (coming from heater core??) has been cut!
-Green arrow: Hose is not connected to anything.

So can it be related to my wet floor problem?
Thanks for all your help and advices!!

Well, it can't be the heater core, because the heater core is not connected (unless the water has been sitting there a long time).

The red arrow is pointing to one of the two heater core nipples, with a hose on it which has been cut. Right next to it is the other nipple, with a red hose on it, which stretches around the evaporator box and seems to be attached to the firewall on the other side, but there is no connection for that host at the point where it is in contact with the heater core (at the green arrow), so I don't know what is holding it there.

The other red heater hose can be seen in the picture bypassing the heater core, connecting the water pump to the hot water valve on the back of the engine.

Both of your A/C lines appear to have been cut near the evaporator.

Thanks again Eric for your help!

So, indeed, water cannot come from the heater core...

The red hose Right next to it, which stretches around the evaporator box and seems to be attached to the firewall, just seems to be attached.

It is not connected to anything.

Can water come from another hose from the engine bay to the interior?

Or at least it was finally really rain that came from somewhere... car has some really bas weatherstips!

 

Yes sir, that rules out the heater core, unless that was done recently. It also can be condensation not draining from the a/c. It could be rain entering through the defroster duct and the drain is plugged up. There are no other hoses that will bring water inside the cabin.

It also could be weather stripping leaks, rot around the windshield or cowl, or something else.

 

I disagree. It's most likely that the heater core is bypassed BECAUSE it was leaking. Once the carpet pad gets wet, it stays wet for a loooong time. Also, simply bypassing the heater core doesn't remove the residual coolant in it. It's certainly possible that there is rust in the windshield pinchweld that is providing a leak path for rain water, but don't rule out the heater core just yet. Personally, I'd rather replace a heater core than weld in a pinchweld patch panel.

 

I agree that it is likely residual water leaking out of the heater core - I've had that happen to me in the past. If the leak isn't on the bottom of the core where the water can all drain out, it can slosh around while driving and leak out.

 

Thanks again for all your replies guys!!

Car will be to the mechanic tomorrow!
Will ask him to check everything and will let you know!!

Thanks again!
