On the back of the motor is a coolant hose fitting that is a known failure point. Farther back than the EGR if I remember correctly. That is on the passenger side so may be where the leak originates. There is a quick connect that corrodes and starts leaking. The hose goes to the heater core. Look around that neighborhood.

Thanks! I'll take a look.

I dont suppose youd know what that part would be called? Im going to have to buy one before i pull the old one ao im not stranded.

Just ask for the heater hose fitting on the intake.. be prepared for it to break when you try to remove it... Lisle makes a tool that will help you remove it if it breaks....

sent from what use to be a great country...

When mine broke I used a hack saw blade and cut four slots till I got to threads. Must be patient and careful. Then took a punch and knocked the pieces in to break them free. Got three pieces out one is floating around in there somewhere. I then tapped the thread and installed new fittings. That was a year and a half ago with no problems. I am not a fan of quick connects on any thing as they always seem to fail or crumble when you need to service them. Snap together manufacturing.

I had the same issue. Part was available at CARQUEST (Advance Auto Parts) under $20..

If you're going to keep the QD type fitting use a steel one instead of the cast type. They are available at virtually all parts stores. I used a fitting that screwed in with a hose barb on the end, slipped the hose on and clamped it.

This is the only way to go. It's just a brass male adapter. I believe 3/4" thread to 5/8" barb.
