ok so the candian cancer ate through one 2 of my rad lines.... they are underneath my 93 4runner and go from the front back past the cat and right up by the muffler... 2 lines come out of rubber and then go back into rubber and they run besides eachother.... any ideas?? if not ill have to go snap some pics

 

Sounds like rear heater lines, if you have one.

 

THANKS I DO HAVE A REAR HEATER.. can i just disconnect them?? i never used the rear heater once before?

 

Sure, you can either cap off each line or just loop the two together at the firewall with some heater line.

 

You mention rad lines in your first post... the rear heater lines don't go from the rad. Exactly where do the lines in question lead to and from, can you be more precise? The only lines that come from the rad are the tranny cooler lines if you have an auto.

 

im not sure if they come from the rad.. they have rad fluid in them... they start ing a rubber hose on the drivers side about under my seat.. they go half way back middle of the truck to about the rear heater... you can just cap them off??? or would i just stick a u pipe in the rubber hoses?

 

Yeah, if they go up to through the floor in the middle of the truck, those are the rear heater lines. You can do either... plug both, or short circuit them with a u-pipe... doesn't matter... just make sure that whatever you do, it doesn't leak.

 

what size is the tubing?? the metal one ??that i am needing to by to make a u shape?????

 

Not sure which tubing that is, but measure and see. For the rear heater, I found 1/2" heater hose fit fine. For my '85, there was rubber tube from the firewall to the hard lines under the truck. Then rubber lines from there to the rear heater. Just take one rubber line at the firewall and loop it over to where the other rubber line connects to. For example, on my '85, connect the red and green circled points together:

 

thanks dude you helped me a bunch.. i found the 2 rubber hose in the engine bay for the rear heater and im gonna connnect them easyiest way to go and the long rubber lines under the truck cant flake away if they are not there!
