heater core

 

Yep. Heater core could be leaky as well as the hoses.

Okay thanks I changed the old hoses from the engine going Inside I guess I mustve moved something

[mjja]

If I block the two water lines to my heater core would it affect my truck like will it mess it up? Doing this just so I can drive around without leaking

[Tristin]

Nope, people bypass their heater cores all the time.

Blocking the hoses would be the same as shutting the temp switch down to OFF. Will not hurt anything.

 

You may have a loose hose clamp but you may also have cracked or disturbed the solder connections by pulling the old hoses off. For what it's worth, always slit the hose lengthwise with a box cutter to remove them when replacing.

Thank you I apriciate the help!:)

yep. as mike says..be careful about taking off the hose, these pipes and or welds are very old..

i would never not have the hoses going to my heater core because i like the option

of using that heater core as a second, emergency radiator if the heat ever climbs up.
