Heater core bypass

I have a 1996 Taurus LX, miles unknown(neither odometer works, shows 36,000+) that just blew the heater hose at the water pump. I live in Guam and will never use the heater. Can I bypass the core with out effecting the engine cooling? Parts are nonexistent out here and internet shopping is tough for this hose as most of the places I've checked always have the photo disclaimer that the part pictured may mot be the actual part ordered.

If I cap the core inlet and outlet nipples and the water pump heater hose outlet, will the engine cooling system be intact and adequate? I'm having a hard time tracing the complete system and I'm thinking the heater may link to the block somewhere. Or not. The Haynes manual isn't much help and appears to serve better as a cutting board.

This my first post and I'm hoping I asked for help in the right forum. If not, sorry and send me where I need to go. Thanks in advance.

You can bypass the heater core without any issues but you can't cap off the outlet of the water pump. You need the flow through the circuit but you can just bypass the heater.

Flow still needs to occur. Bypass, don't block.

Upon further review... the heater core has ALREADY been bypassed. The heater hose coming off the water pump goes to a metal 90, them runs toward the driver's side right against the fire wall..then goes...somewhere. I'm assuming the block to complete the circuit. I can't follow it after it gets to the drivers side. Too much interference. Just hoping I picked the right hose option from RockAuto.

Thanks for the help. Just picked this car up a couple of months ago and the familiarization process is ongoing. I'm beginning to think Ford has a group of 7 year old girls putting these thing together based on the number of places my hands don't fit, when trying to get at various nuts, bolt and clamps. I hate those friggin' factory squeeze type hose clamps.

Have a good day!
