Hey guys, have been looking at this site a lot recently as I bought a 94 4runner. I've ran into quite a few problems as the previous owner didn't take care of it. The past couple days I replaced the radiator, thermostat, and a quite a few heater/bypass hoses. I did a test drive once complete to find a smoky engine, and half a reservoir of coolant on my driveway. Did a pressure test and looks like it's coming out somewhere between the back of the engine to the back driver's side. Anyone have any insight or can help me narrow it down on which hose it could be? I've been searching and searching threads and can't find anything. Thanks!

 

What engine?

 

Probably a 3vzzzzy,
Could be the coolant hose at back of motor, but its more toward the passenger side.
Not that easy to see and can be a pain in the butt half's to replace.

It's just below green arrow.



Hey rworegon

 

It's a 3.0L, V6.

That kinda looks like the culprit, I felt it and it's wet.

 

A mechanics mirror and a good light can be helpful for seeing back there.

Hi ya, ksti.

 

Also when I replaced mine I removed my hood, four bolts and made it a lot easier.

 

It was a serpentine hose on the driver's side. A little bit of beer, a radiator leak tester, and some elbow grease got it working. Thanks guys.

 

Serpentine hose? Never have heard a hose called that.
