What you have to do is unhook the heater core and loop one of the hoses. Go in the engine compartment and unclamp the 2 hoses from the heater core at the firewall [1] in below picture. Also unclamp one of the hoses at the engine, and circle the other hose back onto that pipe, so that one hose is no longer used but the second hose goes from the engine right back to the engine. Let me know if you have questions.

Water coming Inside car from behind heater


The heater coil is leaking, or more likely, the hose connections to the coil in the engine bay are bad. Hoses need to be replaced, most likely. At least that's the first place I'd look.

01 dodge ram 1500 heater blows hot for 15 seconds then goes cold I turn it off wait five minutes turn it back on it will be hot for 15 more seconds the heater hoses are hot and no coolant leaks


sounds like a blocked heater radiator ,,, would be worth flushing it out first before you spend on trying any new parts ,,,only do flushing on a cold engine as you could get badly burned ,,,, locate the heater hoses going into bulkhead ,these are rubber hoses NOT STEEL,,and disconnect them both ,,,, get a garden hose and run the water in one of them ,,,, not too much pressure or you will burst heater radiator and cost yourself a fortune , water should flow freely through ot ,,, then reverse the flow through the other hose ,,,,,,, if alot of dirty water comes out you are on a winner ,,,, just make sure any heater tap on the hoses or rad are opening fully as well ,,, best of luck

I have a 1993 buick park ave and it is leaking antifreeze


If its leaking, its getting over heated because of no water. If its leaking water, you need to check the hoses first, usually old hoses between the radiator and engine burst or have slow leaks. This can not be tested at home, so replacing them is easier, than taking it in for testing. It could be a hose clamp, they are located at the top and bottom of the hoses and just require a screw driver to tighten. Could be the water pump but that makes a whinning noise that you can hear if the radio is not on high. The radiator could have a leak also. best way to find out is fill the water up, and turn the car on and see where its leaking, you might need assistance from someone to raise the rpms by stepping on the gas, make sure its in park. overheating beyond that if all that is good, could be your freeze plug located at the back of the engine in deteriorated. If the engine block had a crack it would usually seize. The block above the engine is wear the cooling takes place, so if the block is cracked it will cause the oil and water to mix and cause overheating, but that is not usually tons of water loss. I would start with the hoses and run the engine and look to see if one is bubbling or leaking. you can spray water on it to see it bubble where the leak is. hoses range from 40-60 dollars because they have insulation coils in them. oh, check the radiator plug at the bottom of the radiator, it might be open or blown.

1985 grand marqius, the heater hoses have been by passed, i've been told it could be that the "heater coil?" may have gone bad, where is the hearter coil located?


Many people bypass the heater core if it is leaking. It stops the leak but then you have no heat.
The core itself looks like a small radiator and is located inside the big box under the dashboard and isn't very easy to remove. You will need a chilton or haynes manual to guide you through the job or bring it to a shop and have them do it.

2004 dodge stratus,heater blows cold. flushed and filled and replaced thermastatestill blows cold. how do i know for sure if it is the heater core?


Remove both heater hoses from motor. Put your garden hose in one end and tape on securely with the other end pointing in a direction the water flow from it will not hit distributor or other vital electronics. Turn on hose - If water come out of heater core at same rate as you are pumping it in then your heater core is flowing - if not then your core is blocked or plugged. Be mindful - if the core is plugged the water will break the seal of the garden hose and heater hose, spraying everywhere, so turn the water on low to check and be ready to shut off quickly!!

2001 kia sportage is over heating but has no leaks. the radiator has been flushed but is very rusty inside. The water is rusty inside the radiator. We have checked the resevoir, it is fine. the water...


Rusty is from running a bad or no mix of coolant. (PH level is off) You may have a water pump that has corroded impellers, and can't move the coolant as well any more. I would start by making sure to flush the engine block again, and make sure you flush water through every possible hose, and where you can get at it.

My ford expedition xlt is leaking coolant from behind the motor and over heating. i have already replaced the thermostat, and the water pump. i was told i may need to replace the freeze plug.


Could be one of the freeze plugs in the back of the block. You'd have to remove the transmission or motor to get to it. Also check the heater hoses at the firewall, the intake too. A mirror on and extension might help.

What and where is the freeze plug(s)..Is it costly to repair, can i do it? Do I NEED TO replace the radiator, it is a 1995, and has no major repairs? Also in solving my heat problem, and I find it is the...


Well the so called freeze plug as you call them is called a CORE plug as when the block is cast in steel/ iron or what ever the core plugs are there to wash out all the Sand and then put in Brass plugs which come out when freezes up,and they are in the block and in the heads Just fill with water and see were it leaks from either side if block or rear of block or in the heads under camshafts.
The block ones you can do yourself by knocking IN and then pulling them out with a big screwdriver but some are a bugger to get at
But if the leak is out side one then you might have to take off the exhaust manifold etc..
(Let me know how you get on with it)
No you dont need a new radiator or heating coil
and when you have repaired it we can also fix the heating problems.. Ron
