Which Heater Hose is the Inlet Hose?
There are two types of heater hoses- the inlet hose and the outlet hose. The inlet hose is the one that goes from the water pump to the heater core. The outlet hose goes from the heater core back to the engine.
Does It Matter Which Heater Hose Goes Where?
It may not seem like it, but the answer to this question is a resounding yes! Though your car’s engine is cooled by antifreeze/coolant, that coolant needs to be circulated by a water pump in order to do its job. The water pump sucks coolant from the radiator and pushes it through the engine block where it absorbs heat.
Then, the now-hot coolant flows back into the radiator where it gives off its heat and begins the cooling process all over again.
If you were to put the wrong hose on your car (or even put them on backwards), then the flow of coolant would be disrupted and your engine would overheat. In short, it’s important to make sure that you know which heater hose goes where before you start your car’s engine!
Do You Have to Drain Coolant to Replace Heater Hose?
If your car is like most, the heater hoses run from the engine block to the heater core under the dash. Over time, these hoses can become brittle and crack, causing coolant to leak. To replace a heater hose, you will need to drain some of the coolant from your engine first.
Here’s how:
1. Locate the coolant reservoir under the hood and remove the cap.
2. Place a large pan or bucket beneath the radiator drain valve and open it up to drain the coolant into it.
3. Once thecoolant has finished draining, close up the radiator valve and removethe lower radiator hose from its connection at the engine block.
4. Follow this same process for removingthe upper radiator hose if necessary (some cars have only one hose runningto the heater core).
5 .
With both hoses removed, you should be ableto access and remove any clamps or brackets holding in place your oldheater hoses. Install your new hoses in their place making sure to usenew clamps or brackets as well (reusing old ones could cause leaks).
How Do You Temporarily Fix a Heater Hose?
If your car’s heater isn’t working, one possible reason is a leak in the heater hose. If this is the case, you’ll need to temporarily fix the hose until you can get it replaced.
There are two ways to temporarily fix a leaking heater hose.
The first way is to use duct tape. Wrap the duct tape around the leaky area of the hose, making sure that the entire leak is covered. This will provide a temporary seal and should hold until you can get the hose replaced.
The second way to temporarily fix a leaking heater hose is to use a patch kit. These kits come with everything you need to patch up small holes or leaks in hoses. Simply follow the instructions on the kit and apply the patch over the leaky area of the hose.
Again, this will provide a temporary seal and should hold until you can get the hose replaced.
5.4 Ford Expedition Heater Hose Replacement – No Special Tools Needed
2005 Ford Expedition Heater Hose Diagram
If you need a 2005 Ford Expedition heater hose diagram, you can find it online or in most Ford dealerships. The Internet is a great resource for finding diagrams for just about any vehicle; however, make sure you get the specific diagram for your model of Expedition. Many sites will have generic diagrams that might not match up exactly with your vehicle.
The dealer should be able to provide you with a printout of the heater hose diagram from their service department. If they don’t have one on hand, they can usually order one for you. Be aware that there might be a charge for this service.
Once you have the diagram, trace the hoses to see which one needs to be replaced.
If your Expedition is still under warranty, take it to the dealership and they will likely replace the heater hose free of charge. Otherwise, replacing a heater hose is generally a fairly easy do-it-yourself project.
You’ll need some basic tools and supplies, including new clamps for the replacement hose. Follow the instructions in your repair manual or on the websites linked above, and you should be able to handle this repair without too much trouble!
Ford 5.4 Coolant Pipe under Intake
If your Ford F-150 or Super Duty has the 5.4L Triton V8 engine, you may be experiencing an issue with the coolant pipes under the intake manifold. These pipes are responsible for carrying coolant to and from the radiator, and they’re located right next to the hot exhaust manifolds. Over time, the heat from the manifolds can cause the plastic coolant pipes to degrade, resulting in small cracks and leaks.
If you notice your truck is leaking coolant, especially from around the area of the intake manifold, it’s likely that you have a cracked or leaky coolant pipe. In some cases, these leaks can be repaired by simply replacing the damaged section of pipe. However, if the damage is severe enough, it may be necessary to replace the entire length of pipe.
If you’re having trouble with your Ford 5.4L Triton V8 engine, don’t hesitate to take it to a qualified mechanic for diagnosis and repair.
