Most times you have to slide under the car to see them . if you jack the car up make sure you use jack stands to support the vehicle or have ramps this is for your safety.

I need to bypass my heater coil as my aircon is leaking 2003 kia pregio any photos?

Im not quite sure what bypassing heater coil has to do with aircon leak, unless you mean there's coolant leaking from under dash, if coolant is leaking, remove hoses at firewall and follow them back to engine, you can use one of them to bridge from one to the other. Or put a connector between the hoses

Where is the inlet heater hose located on a 2005 Hyundai Elantra?

You wouldn't even be able to see it from this angle. It will be on the firewall. There will be two hoses (rubber) next to each other that are the same size. They are likely 5/8" hoses. The inlet is typically on the passenger side. Make sure the hoses are rubber. The A/C lines run into the firewall near that area but they are metal.

Heater core metal hoses

Hi I'm Peter, Curious as to why you said metal hoses as most heater cores have metal pipe inlet and outlets that protrude out of the firewall and then the rubber heater hoses are connected to them. I may have to go look that one up but my question is are you taking the heater core out, and if so have you already take the dash area out to access the heater core? Let me know and I'll see what I can do to help but right now I am wondering if you might be talking about the transmission coolers metal lines. Sorry I'll wait on your response.

Bypassing Heater Coil

Hey Leigh.
The firewall is the big thing that separates the engine from the cabin,, its the thing the dash is bolted to. I WOULD HIGHLY RECOMMEND TAKING THIS TO A RADIATOR SHOP/AUTO REPAIR SHOP, tell them your story, and then ask the them how much they would charge you to cut and splice the heater hoses. The hoses run through the firewall somewhere in front of where the passenger sits, the hoses run from the radiator... then have valves and connectors in them. you will need some type of female to female connector and two hose clamps..YOU MUST do this when the engine is COLD.. you don't want to attempt this with HOT antifreeze!! This is not something you can do without a fair amount of knowledge about how automotive A/C and heater systems work.. Once you can identify the correct hoses... it won't be could actually bypass ALL the valves and connections.. Find the two hoses that come from the radiator and splice them together when you find a length of hoses that will facilitate a connection loop.. please rate as helpful..

Where is connection

    • Locate the accumulator bolted to the firewall on your automobile. It usually bolts to the passenger side firewall but this is not a rule. However, it will be located on the passenger side of the engine bay. The accumulator is approximately 12-inches in length, 4-inches in diameter and has at least tow large hoses extending from it. These hoses are the high side and low side hoses. Locate the metal portions of the high side and low side hoses. Each hose comprises of a hard-metal line and soft-rubber line secured together. The metal portion of the hose bolts to the accumulator. Locate the low side and high side valves. They are located on the metal portion of the hose connected to the accumulator and both have black plastic caps covering them. The high side valve is a 16mm quick disconnect valve and the low side valve is a 13mm quick disconnect valve

Hey John,
You should find two hoses leading into the passenger side of the firewall under the hood, one is input, the other is obviously output,. cut & splice,. you should be fine (as long as it doesn't get too cold where you are)...

Can you tell me where to find my heatercore hoses on my 1994 cadillac sedan deville?

The heater-core hoses are usually paired together behind the engine, and they go through the firewall. Two rubber covers usually hold them tightly to the firewall. They are not that dificult to identify.
If your heater still works, they get quite hot, and you could feel them to further identify.

I recently replaced my oil pan gasket in my 96 F150 6cyl, 4.9L.

if you have the 4.6L engine the hoses both connect at the back of the engine on the right side to a black pipe and a silver pipe the silver pipe stands straight up and the black one is at about 45 degrees, generally speaking the heater hoses come from the water inlet and outlet to the core (firewall) the flow or direction of water travel does not matter one is in and the other out of the core, to be for 100% sure I would have to know what exactly engine you have. Hope this helps
