Lost hose below two heater hoses and unable to find proper name for hose to replace it. Can you assist?
Hose that is located underneath the two heater hoses came off when driving. I am new to working on my vehicle and attempted to plug the hole, so to speak. Once that was done, water started coming into the car from under the dash. I am hoping the added information will help with identifying the hose. Until I know the name of the hose, I cannot replace it. I did take a picture in an attempt to try and show someone where it is located. Help would be appreciated.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hi there. The hose that you are describing sounds like the heater core by-pass hose. If the hose is short and straight, then it would be the heater by-pass hose. The heater by-pass hose it to by-pass the heating system until the engine is hot. If you need further assistance with your coolant hoses, then seek out a professional, such as one from Your Mechanic, to help you.

The two hoses are the transmission oil cooler lines that run from transmission steel lines to the radiator oil cooler connections. They need to be high pressure power steering type hoses to hold transmission pressures.
There are two types of radiator hoses – upper and lower. The upper radiator hose is a pressure hose that connects the engine to the radiator. The lower radiator hose, which is attached to the bottom of the radiator and the water pump, serves as a suction hose.
Both the upper and lower radiator hoses are the largest hoses in the cooling system connected to the engine. Heater hoses are smaller hoses that are attached to the heater core, which is located under the dashboard, to supply warmth to passengers in the cabin.
The basic automobile cooling system hose is the upper and lower radiator hoses. These hoses look the same but they cannot be interchanged because they are designed for different purposes just as stated. Other functional hose includes the overflow tank hose, heater core hose, and thermostat hose.
Most cars have two radiator hoses called the upper and lower hoses. The upper radiator hose transfers hot coolant from the engine back to the radiator, allowing the coolant`s heat to be removed. Once the heat has been removed from the coolant, it is sent back to the engine via the lower radiator hose.
Coolant hoses come in two flavors – heater hose and radiator hose. They hoses are made the same, but the sizes are real difference. Heater hose is generally ½, 5/8, and ¾-inch in diameter. There are different types of heater hose, from standard to heavy duty.
The radiator inlet hose (cylinder head outlet hose) is 2 inch inside diameter, and the radiator outlet hoses are 1-3/4 inch inside diameter.
The heater bypass tube is a cooling system component found on many road going cars and trucks. It`s purpose is to serve as a cooling system passage that bypasses the thermostat, so that there is coolant flow even when the engine thermostat is closed.
Two-pipe and single-pipe systems
A second pipe (called the `return pipe`) collects the cooled water from the radiators and carries it back to the boiler for re-heating.
There are inlet and outlet ports, which from the inlet port coolant flows to the tubes where they are exposed to cooling. The tubes are in a parallel arrangement, where they come in contact with cooling fins to draw away heat from the core.
The small tubes go to the high points in the cooling system, so that when you fill the coolant, the air doesn`t get trapped there. On the cars that got only one connection on the expansion tank, there is usually an air valve at the highest point, that you open to bleed out the air until the coolant starts coming out.
The lower radiator hose is primarily a suction hose. The water pump, as it spins, draws coolant from the radiator into the engine. This creates an area of low pressure at the bottom of the radiator, which can cause an ordinary hose to collapse.

PCV hose broke, car stalled, replaced hose, car still stalling. Smell of gas (rich exhaust smell).
ANSWER : Hello. You do likely have a major boost leak or vacuum leak present. Volkswagen’s are very sensitive to any type of vacuum leak. On Volkswagen’s, even if the oil dipstick is is removed it will produce a vacuum leak cause the engine to idle erratically. I suggest that a smoke test is performed on your vehicle by a shop or technician which well help find the leak(s). A different way to test it is to spray starting fluid around your areas where a vacuum leak might be. The RPM’s increasing when spraying starter fluid would indicate that there is a vacuum leak present nearby the area being sprayed.

What’s the name of this hose nobody seems to know or mention even in Google?
ANSWER : The hose you are referring to would be the bypass hose. It is very possible that plymouth may have a different name for the hose but the typical name for this hose is the bypass hose.
This hose allows coolant to bypass the thermostat to keep the circulation of coolant going through the engine before it has reached operating temperature.
Depending on how the hose connects to the vehicle, you may be able to just get a piece of bulk hose that is the same size and length as the old hose and just use that.
If you need assistance with replacing it, have one of our mobile technicians come to you to diagnose any issues firsthand and replace your bypass hose as necessary.
Do i need to replace the receiver drier and/or the expansion valve when replacing the condenser assembly?
ANSWER : Replacing the system drier is absolutely essential. If the system has been open to the atmosphere (due to the leak in the condenser), the desiccant in the drier has been fully saturated with moisture. As far as the expansion valve, replacement is not normally implicated in a leak repair, in your case a leak in the condenser. To justify replacing the expansion valve, there would have to have been a diagnostic performed which proved a fault. If no diagnostic was performed, and there is no evidence of a fault, then it is pointless to replace the valve. But, again, drier replacement is absolutely essential. To add the drier to your order, you can simply add a note to the mechanic in your order and/or add it as a service (you will see a link that you can click on to "add services" or write in specific services).

There’s a hose under the top radiator hose that seems to be leaking antifreeze. What hose is that and is it an easy fix?
ANSWER : Hi there. Usually the hose that’s directly under the top radiator hose is a return surge tank hose; typically coming from the radiator overflow coolant reservoir. Since winter is coming around soon, the best way to diagnose a coolant leak and to ensure it’s not your heater core of heater hose is to contact a professional mechanic and have them complete a coolant leak inspection. This service is the best way to eliminate the guess work and ensure you’re Chrysler 300 is repaired sooner rather than later.
Overheats when heater is on, heater blows cold air.
ANSWER : Since you had cooling system work done recently, one possibility is the cooling system is air bound. If air is trapped within the cooling system and not properly bled from the system after a repair, the air can cause the coolant to not circulate properly. This can lead to overheating and no hot air from the heater. Another cause that can simply be coincidence is a stuck thermostat. The function of the thermostat is to allow the engine to reach a certain temperature before opening and allowing coolant to flow throughout the cooling system. If the thermostat is stuck closed and fails to open, the coolant will not flow properly and cause the engine to overheat. The heater will blow cold air because hot coolant is not flowing to the heater core behind the dashboard to provide heat for the interior. Have a certified technician diagnose the engine overheating as soon as possible. Continued driving while overheating can damage the engine.
How do I know I have two resonators? Can I have two mufflers in each side with one resonator? Which side is most important? Thank You.
ANSWER : You may have a single small resonator in the middle of the car that splits to the two mufflers. One on each side with single or dual tip outlets. The two mufflers are equal to each other to exit the exhaust flow. For more concrete advice, I’d recommend having an expert technician check out your specific muffler situation in person. A technician from YourMechanic can come to your home or office inspect your exhaust system and assist with any repairs that are needed.
I just replaced a heater hose in my 2006 dodge ram 1500. The coolant is full but now the engine is overheating. Did I miss a step
ANSWER : A diagnostic would determine the root cause of the overheating. If the coolant level is low, and/or there is trapped air in the cooling passageways, perhaps related to the heater hose repair, those faults themselves can cause overheating. The other common causes of overheating include a faulty thermostat, a plugged radiator, collapsed hoses, and a faulty water pump or drive belt. Certain engine faults, such as a leaking head gasket or poor engine running condition can also cause overheating. If you desire that this problem be diagnosed by a certified Mechanic, dispatched by YourMechanic right to your location, please request an engine overheating diagnostic and the responding certified mechanic will get this resolved for you.
