What Hose is Connected to the Coolant Reservoir?

The hose that is connected to the coolant reservoir is typically the upper radiator hose. This hose carries the hot coolant from the engine to the radiator, where it is cooled off. The coolant then flows back down to the engine through the lower radiator hose.

If there is a problem with either of these hoses, it can cause the engine to overheat.

How Do You Fix a Broken Coolant Hose?

If your car has a coolant leak, it’s likely that you have a hole or crack in one of the cooling system hoses. These hoses are responsible for carrying coolant (a mixture of water and antifreeze) throughout your engine to keep it at the proper operating temperature. A small leak can quickly turn into a big problem, so it’s important to fix it as soon as possible.

There are two ways to fix a broken coolant hose: patching or replacing. Patching is only a temporary fix, but it can be done in a pinch if you’re leaking coolant and need to get to a mechanic right away. To patch a hose, simply clean the area around the leak with soap and water, then dry it off.

Next, apply sealant designed for automotive use (such as RTV silicone) around the hole or crack. Let the sealant cure for 24 hours before adding coolant back into the system. Replacing the hose is always the best option if possible, as patches rarely hold up over time.

To replace a hose, first drain all of the coolant from your engine (be sure to catch it in a container). Once drained, remove any clamps or other fasteners holding the old hose in place and pull it off. Take note of how the hose was routed before removing it so you can put the new one on in the same way.

Slide on the new hose and secure it with clamps or other fasteners.

How Do You Remove the Heater Hose on a 2012 Ford Focus?

Assuming you would like tips on how to remove the heater hose on a 2012 Ford Focus: 1. Locate the two bolts that hold the heater hose in place on the firewall. Use a socket wrench to remove these bolts.

2. Have someone help you pull the hose off of the firewall, as it may be difficult to do so by yourself. 3. Once the hose is removed, take a look at the O-ring that seals the connection between the hose and firewall. If this O-ring is damaged, you will need to replace it before reattaching the hose.

4. To reattach the hose, simply reverse these steps – start by placing the O-ring onto the firewall, then fit the end of the hose over it and screwing in both bolts until they are tight.
