Question about 1994 Chevrolet Silverado 2500

1 Answer

I have a 1993 Chevy Silverado 2500 with a 5.7 liter 350. How do I bypass the heater core by connecting two hoses? Will the only negative impact be that I will not have a heater?

You can remove both hoses from the core and put them together using a short length of copper plumbing pipe. No problem to engine from this it flows through just like its going to core( engine can't tell the difference)

I bought a 99 tahoe four door 5.7 350. No heat. Previous owner bypassed heater core. Need to see how heater hoses attach.


Have you replaced the heater core? If not, most likely the reason the previous owner bypassed the heater core was because it leaked. I will be happy to send you photos of how the hoses attach but I will need your email address.

I have a 1993 chevy 1/2 ton pickup with 5.7 liter. I am getting little or no heat from the heater after having the heater core nad Thermastat replaced. It is full of antifreeze.


Can you feel the hose going into the heater core? Is it hot? No?

You might want to find the heaters flow valve and check it. It's probably stuck in the closed position.

I have a heater core leak on my 2000 chevy silverado V6, is there an easy fix?


You can bypass the heater core, you just wont have heat anymore. On the firewall of the truck, behind the engine, you will see 2 rubber heater hoses that go into the firewall. They attach to the heater core. Disconnect them and get a plastic connector, and connect the 2 hoses together with clamps to hold them down. This will stop coolant from going into the heater core, and no more leak.
