Where are heater core hoses in 2003 dodge grand caravan?


You will find them under the hood.
Do you know what the heater core is? About the size of a hard-back book, it is a small radiator with engine coolant passing through it. It is located inside the heater case under the dash.
There are two hoses, an inlet line and a return line. Both same size, about 1 inch in diameter. Both hoses come from the engine and go up to the firewall behind the engine. Both hoses connect to the heater core right at the firewall, so there are hose clamps on the end of the hoses.
You can remove and replace the heater hoses right there under the hood, pretty easy too. But if you need to replace the heater core, that comes out from under the dash. Often there is a lot of work to get to the core, as there is a loot in the way.

2005 town and country heat does not work it only blows warm air i changed the thermostat and its still the same


No.
There are no heater control valves of years gone by. And if the water pump was not pumping the engine would run very hot.
If the radiator is full, and the thermostat is working, the heater hoses should be hot, and the problem could be a faulty blend door under the dash. The blend doors direct air thru the heater core and the ac evaporator as well as the vents.

My camaro is over heating and the coolant is leaking onto pasanger floor inside car, i need to bypass the heater core but i dont know what two hoes to connect or what the heater core looks like or where it...


Two hoses will run into your passenger side firewall area under the hood. Probably within inches of eachother. They will have hose clamps or clips of some sort. They will be about an inch and a half in diameter. Pull them off and prestone or water should come out of both. Hook them together.
Heater core looks like a very small radiator. With an inlet and outlet. Made of brass or something similar. Sits in your heater duct after the blower moter.

It is geting water inth air and ventilation system and throw it ina the cab


It's most likely a heater core leak. Hot radiator fluid is passed through the inside of the heater core, and air is passed over that. if there is a pin-hole leak in the radiator core, then it will come out of the vents. Turning off the heat setting will not change the leak either, it will still leak and collect in the lowest spot, and then blow out the vents when it strikes the fan impeller blades. the heater core is fed from 2 smaller radiator hoses. If you look under the hood, you'll see 2 large hoses that come out of the radiator. you'll also see 2 smaller hoses that go back towards the front of your car through the firewall. these 2 little hoses go to your heater core. Most cars require dash removal to change out the heater core. Unless you are pretty handy, I'd leave this one to the shop.

SAAB 9000 CSE 1996 - Coolant likage


With the vapor coming out I would say you have a hole in one of the heater hoses which go into the firewall in the area you describe. Inspect the hoses looking for the vapor with the engine still hot.

It could also be a leak in the heater core. The vent the vapor came out of is the source for fresh air for the heater and a/c. You should be able to smell antifreeze with the heater on inside the car if the leak is there. Water may also drip on the passenger side floor from the heater core.

Peugeot 306 temp use to reach 80 degrees drained coolant and replaced no temp reaches 98 but blowing cold air


The head gasket has gone, is it a 1,6 1.8 petrol? if so its the most common fault on that car. best way to tell pull the dipstick up and look at the very bottom if it looks creamy white then its the head gasket, also open the oil cap and look inside the head and on the cap any white creamy sludge means there is water in the oil, "head gasket"

Hope this helps

As the car was at 98 you will have warped the cylinder head so will need skimming costing £40 new head gasket fitted is about £170 do it your self for about £80

No heat is there a fuse 2003 f250 is there a fuse for heater


i don't know realy if there is a fuse (though i doubt it) but issues with heatting may be this will help.

If the carpet under the heater core is damp, or if antifreeze vapor or steam is coming through the vents, the heater core is leaking.
Remove it and install a new unit (most radiator shops will not repair a leaking heater core.
If the air coming out of the heater vents isn't hot, the problem could stem from any of the following causes:
  • The thermostat is stuck open, previnting the engine coolant from warming enough to carry heat to the heater core. Replace the thermostat.
  • There is a blockage in the system, Preventing the flow of coolant through heater core. Feel both heater hoses the firewall. They should be hot.if one of them is cold, there is an obstruction in one of the hoses or in the heater core,or the heater control valve is shut. Detach the hoses and back flush the heater core with a water hose. If the heater core is clear but circulation is impeded, remove the two hoses and flush them out with a water hose.
  • If flushing fails to remove the blockage from the heater core, the coremust replaced.

Blower Motor Location


Look under the hood on the fire wall where the heater hoses go into the interior ogf the car. The heater core is just inside under the dash. theree is no easy way to tak out the heater core. But it is done all the time.
Do that only if it's leaking and the carpet under the dash is wet. If not, try flushing the heater core .With the engine cold and the radiator empty, Take both hoses off that connect to the heater core. Insert some hoses to both the inlet and outlet so you can direct the water down and away from the engine. With a good stream of water pressure. Put the water hose into one of the inlets. And spray the water in until it comes out the other hose. Flush out everything that may be clogging the core.
