Chevy 350 heater hose hook up

Chevy 350 heater hose hook up

The heater inlet hose is on the firewall. This will bypass the heater core without impeding cooling effectively. You should replace both connectors at once to avoid a repeat situation.

Any help would be appreciated as this is really bothering and I would love to get him out on the road without fear of overheating and blowing something up. What I don't know is which way it is flowing. Both heater hoses will be connected to nipples, which go through the firewall and into the heater core.

Allow the system to cool before working on any heater hoses. Allow the vehicle to reach operating temperature so that the thermostat is allowed to open and closely watch the connection points. Cutting the disconnect can be done using a hand saw with a hacksaw blade or with a small air-powered reciprocating saw. This is very important- extreme care must be taken when cutting the connector, as too much shaking can break the heater core.

How do you hook up the heater hose on a Chevy

Auto parts stores also sell heater hose repair kits that come with pre-formed plastic connectors that will work well also. What also scares me is if my engine really is not overheating. Otherwise you'll have it all over the inside of your engine. Much like a fuel line disconnect, the water hose tool is two half-moons with tabs that slide in behind the connector. Bypassing is not a complicated task, but the correct components must be present to divert the coolant around the heater core successfully.

Allow the system to cool

The small plastic tool folds around the backside of the tube, and is slid into the connector until the fingers are released. To bypass the coolant around the heater core, it is necessary to divert the heater hoses coming from the engine to somewhere other than the core itself.

Or could the flow be going from the water pump into the manifold and is my thermostat functioning weird. No it will not, it will just back flush the heater core and clean it out. One goes from the heater core to the water pump, the other goes from the heater core to the intake manifold. Personally I'd pay a mechanic or find a handy man on craigslist and give him the core. There are two hoses that connect to the heater core, and they are located next to the brake master cylinder, on the driver side of the van.

If the heater hoses are connected properly and clamps are tightened down, the system should contain no leaks. For the heater core, I'd say go to a junk yard and get a new one.

This step requires you to have the fix on hand in case of an emergency, but if just bypassing the core in your driveway then it can be purchased after the incident. The disconnect tool works by releasing the spring fingers on the inside of the connector. But the real trick is getting the connector off the pipe.

Cutting the disconnect can beAllow the vehicle

Could my high flow water pump be pushing liquid through the engine to fast and the flow from the manifold via the heater system slows it down. All you need are pliers and a new hose. The hose on the water pump may have similar connectors, you can leave it place or replace it at the same time. Depending on which way it goes could help isolate the issue. The key to cutting the connector is to make one straight cut across the top and another slice across the bottom, splitting the connector in half.

Take it down to autozone, and they should have the hoses there, if not, then go to home depot and see if they carry these hoses. On the Silverado itis close to the bottom of the firewall on the passenger side. One of the hoses has a plastic Y on it, one hose goes to the heater core, one comes from the radiator overflow canister, and the other side goes to the water pump.

This is very important

Start the engine and check for leaks. It is not a bad idea to preemptively attack this problem and replace them before one breaks and leaves you stranded.

First take the old hose off, and make sure you don't lose the clamps. You can replace this Y with one that does not have bonded hoses, or you can reuse it. Then the connector simply slides off the pipe. These vehicles are incredibly difficult when it comes to changing the heater core, it requires removing the entire dash, and is an hour process. The tool slides into the fitting to release thehose.
