Santa FE SM (2001-06) :: Heater Core Leaking Coolant And It Dripped All The Way Down To Original ECU
Jan 13, 2015
The problem started when his heater core was leaking coolant and it dripped all the way down to his original ECU. Car stopped working. Then he went to a Hyundai dealer to fix the problem but they said he had to buy a brand new one. First ECU didn't work. Returned it and bought one more expensive. Dad told me it worked but he didn't by pass the heater core so coolant dripped again. So now I'm on my third ECU but it doesn't work. I've read online that some older cars have plug-and-play type of ECUs that aren't restricted to the VINs. His car is a 2004 Hyundai Santa Fe GLS FWD 4dr 3.5L.

My 2001 PT Cruiser began to over heat today. By the time I immediately pulled off the road and smoke began to come out from under the hood. Once I stopped I heard a bubbling noise and watched as all my coolant steadily dripped onto the ground (almost a pour). What does this mean?

Coworker's 2000 Focus's heater core started leaking on his 50m commute this morning. He is ready to donate the car at this point. Any stop leak product (i.e. Bars) that would stop the leak without clogging the cooling system.

I have a 89 ford mustang with 4 cylinder. After being stored for the winter I noticed anti-freeze leaking from drain tube below heater core (small amount). I am not looking forward to replacing the heater core in this car! Any reason this happened after the car sitting in storage all winter??? or just a coincidence??

I purchased a 2002 Dakota and have had a hard time ridding it. I thought that the heater core was leaking and getting the passenger side floor wet, but it's the overflow for the evaporator under the dash. The drain must be plugged. Will I have to remove the dash to pull the heater unit down far enough to clean it. I don't think I can do much from under the hood...too tight.

I have an 02 passat with about 85K and the other day my windows would not clear up and a faint smell of antifreeze. also when temp control is in cool and you move the temp control to warm steam comes out of vents. I need to know if i could change this myself and if any procedure on how to do it.

I just flushed my coolant. Now I got more water than coolant, and in the heater core! I got some 50/50 coolant, cause cannot find 100% Asian coolant.

I have a 08 f-150 with a 5.4. Started smelling anti-freeze in the cab, with that classic windshield haze of a leaking heater core. I don't have anything on the floor, nor is the engine heating up. Temp gauge is where it always is. This doesn't smell all the time.I just drove 4 1/2 hrs. with no problems. Other than the heater core ?

Okay, the vehicle is a 1988 E250 ClubWagon 7.3 IDI diesel with front and rear AC/heat. I have 3 questions for you:
1. I found that the rear heater core is getting coolant flow constantly which is making my rear AC blow 75* air. These models don't have a blend door in the back, they appear to have a valve that is only allows coolant flow to the rear heater core when the heat is turned on. Problem is that I can't seem to find where this valve is located on the van or what it is called to locate it at a parts store. Where on my van this valve is located?
2. My rear blower only functions on High. I know there is a resistor set up in the rear that controls the blower speed. Before I just replace this, is there a way that I can test it?
3. Is it possible that the Resistor setup for the rear fan speed would also be causing the rear coolant flow valve to not work? I know it's a long shot, but does the valve signal flow through it when the AC is on to tell the coolant valve to shut?

I bought a 04 explorer with a bad thermostat which led to a bad head gasket, fixed that and managed to not have to buy the special tools or time it , but now that its running I don't have any heat. I have complete service records on this vehicle and there was never a complaint of the heater not working. The a/c works and the heat will adjust the a/c temp, but no heat. In trouble shooting it I found that I am not getting vacuum to call for the coolant to enter the heater core. When I apply suction to it, it will send the coolant. Even though I wasn't getting the clicking noise, I pulled the blend door actuator and it looks surprisingly good (not looking forward to putting it back in). Where to look next?

Plastic coupling between core and hose, is there a specialty to needed to remove from heater core?

I have a leak where my heater core tube goes into the intake at the rear pass side of engine. I have read that this part is pressed in. I dont want to remove the intake since i just paid $400 to have a new gasket kit put on. My question is can I bypass this tube with a hose from the water pump like in this video?
FORD 4.6 , 5.4 , 6.8, HEATER HOSE UNDER INTAKE REPLACEMENT THE EASY WAY !!! - YouTube....
If I can do a rubber hose like in the video I was to make sure that the tube just goes through the intake and that it does not supple coolant into the intake??

The heater on my 2001 ford F150 is not heating. The blower is working, the inlet hose is hot, the outlet hose is cold. Removal of hoses confirms that there is very limited flow through the heater core. I flushed it but got only minimal improvement. However when I back flush (reversing the flow through the core) the flow is great. Here's the question: Can I reverse the flow through the heater core on a permanent basis? It seems this would give the needed flow of hot fluid through the core to allow heating. Is there a problem with doing this?

I replaced the heater core in my truck. Now it will not turn over. When the key is turned on all the lights in dash come on like normal but when I turn the key to start it I get nothing.

I have an 01 Mercury Cougar Sport Coupe that we bought from a friend for not too much, just to use as a daily driver. It's got a lot of miles on it, but it still gets good mileage, which combined with the fact that we didn't pay much for it makes it an okay car for around town.
Here's the problem. I live in Wyoming where it's winter nine months out of the year, and the heater core is apparently blocked. I made it all through last winter with this problem, but now it's intolerable. The kids call the car "the Red Icicle". My mechanic diagnosed the problem as a blocked heater core and tells me the only solution is to replace it, which costs something like $500. I can't work on the car as everything is too jammed under the hood to get access to anything.
Do I really need to replace the heater core? The whole car isn't worth much. Is there something I can put in the cooling system that will unblock the core reliably?

My heater core must have sprung a leak this week. Not that I need heat in this weather but just the smell of it while running the A/C just stinks. I know I am going to have to replace it myself but just for S&G, what would a dealer charge to replace it?

I've got a 01 sbcc 2wd 5.4 gasser and I've gone thru 3 heater cores in 18 months. Is there something I'm missing?

I recently replaced my heater core on 2001 F250. Would be a simple job if it weren't for the quick connects on the hoses. Any tool to take these apart on the truck where space is limited?

I am talking about those two hoses going into the firewall by my Blower Motor assembly that may be leaking and wanted to know if i can bypass or plug up these two hoses, since i no longer have ARA A/C and heater.
1986 140 CID GAS Ford Ranger 2.3, 5-speed manual
After market ARA A/C - No longer working
Blower motor heating coil element caught on fire - heater no longer working either.
Most days, before I drive somewhere, even just a few miles or less, I have to put in a little coolant, about one or two cups, So I know there is a leak coming from somewhere, it's just not visible, but strangely dripping from my right side front fender wall, just below the air filter, seems strange. Did not see any tiny leaks from my radiator.
What I have done was to check hoses from the radiator to the engine and noticed no leaks. Is there anything else I could do without a major repair? I even used that stop leak a while ago, but that didn't work.
A few days later.. Ok, when I got home today, I noticed antifreeze dripping from that shield over the right side passengers wheel well. I crawled underneath and on the other side of the tire, and did not see anything as the source. I would think that it would be in the area of the radiator, either upper or lower hoses, or that short hose to the block near the water pump. I will check the heater core hoses going from engine area into Firewall again. But I did not see anything leaking from that right side firewall. I have an aftermarket ARA AC, bit that hasn't worked for years.
If the leak is not coming from the head gasket, upper or lower radiator hoses, or those two hoses going into the firewall, where else could it be coning from? Very strange it's not anywhere near the radiator or engine, but on the right side passenger's side, above the tires wheel well. Some have said it has to be from either those two heater core water hoses going into the firewall.
I have neither a working air conditioner (after marker ARA) or a working heater (leaves found their way from the outside hood vents into the Blower motor and EVAP core and the heating element caught some leaves on fire and burned mostly everything inside this box. I have not replaced that, nor would I at this point,but just want to fix the leak)
A friend suggested that I could just BYPASS the water hoses going into the firewall....is this plausible? Do I do next to the inlet/outlet hoses bt the water pump. or somewhere else?

The leak looked like it was coming from a heater hose. The individual I bought it from said he fixed it and it wasn't leaking the day I bought it. Upon driving it home...cranked the heat up and windows fogged, switched to defog with no luck. Added some coolant and still the same thing and leak began again.
It smells like antifreeze inside and fog has oily feeling when wiping it off the window. Got in on the lift and no luck seeing where it was leaking from, even with it running. My previous experience with bad heater cores is that it leaks on the inside and smells like coolant... is it leaking on the outside or is it something else?
It's NOT overheating or blowing any kind of smoke. Temp gauge read normal! It's a 4.3L, 1994 Caprice LS .....
