Yes. Pull off one of the hoses, run down to the hardware store to get a piece of pipe 2-3" long to fit the hose, connect with new hose clamps and you are happy again.

NOW: since you have done all that(bypassing the heater) run your truck a few days and see if you are still losing coolant. The problem I ran into was that the clamps on the hoses running into the fire were not tight; allowing leakage into the cab. Heck check this first before trying everything else. Another thing is to look at the pipes going into the fire wall to see if the coolant is staying in the heater core or if you simply had some loose hose clamp.

Make sure to keep an eye out for more leaks, everytime you fix something the lost pressure you had with the previous leak is there again and thats why new problems surface. sooner or later, you'll get all the leaks fixed

Try twisting them to break em' loose first, then wiggle them off.
If that doesn't work, your gonna need a plasma cutter and a Factory Service Manual for the secret tip hidden on page 972A...

They are hoses man!!! Come awn people...

SEARCH under HOSE removal

Oh yeah I've removed em'.... It ain't rocket science here. Either cutem, jab a screwdriver/pick between the hoses, razor blade em' amd replace the hoses all together (10 bux for new hose and some clamps) or get the damn plasma cutter and the manual!!!

And Tanman2003... get some of those grip exercise thingies, wuss.

hell i couldent figure out if the hoses under the hood go through the firewall and onto the heater core tubes, or if the heater core tubes went thought the fire wall and then the hose goes over the tubes.

Thought the same thing, but they will bust loose. If they won't then just cut em' and razor blade off what's left on the tubes to remove the core... I see Defazio is in Washington and it would suck to have no heat for the rest of winter.... you can get the replacement core from checker or Vatozone for not that much!

LOOKY! $46 bux for a replacement! http://www.partsamerica.com/ProductL...or=Heater+Core

I pulled the dash and heater out of my truck today so I could paint the interior, and I wasn't sure I want/need to put the heater back in.

I searched for "heater bypass", found this thread, and the answer I needed.

I'll post pics when I'm done.

if your getting leaks from those factory wire hose clamps replacing them with the worm drive hose clamps will help but you should think about replacing your hoses.
