Exactly what brad said. If it is the heater core, they will charge you a core charge, so just be prepared for that. Hoses, are obviously a really better idea to have fell on you, but more commonly it's the core itself. Unfortunately.

First you have to determine if this is the hose or the connection to the heater core itself. This can be difficult to do. You should get a pressure testing machine for automotive cooling systems and use it. When you pressurize the system you can see where the leak is exactly. If it is hoses that are bad you can replace them. If it is the pipe that connects to the core (the nipple) then you need the whole core. When you replace the items that are bad you need to use permatex on the connection to be sure it wont leak again.

What are the chances that transmission fluid could get into your oil on a 2007 Ford Explorer Sport Trac


Not that good although it could happen
You would need a leak inside the radatior between the oil colling system for the transmission and a leaking intake manifold gasket that is letting collant leak into the engine that has trany fluid nixed with it .Of coruse you would see oil floating on top of the antifreeze if you removed the radiator cap or the fluid res
. Also look at the engine oil for white foem this also means collant is getting into the engine oil white smoke out the exhaust sure sign you have a leak someware .

The car was bone dry on antifreeze. while driving yesterday could smell antifreeze and i have no heat


prob heater core, roughly 750 to replace, whole dash needs ripped out..unless it is just a hose off at the firewall leading to the heater core or leaking radiator hose..fill the system with clean water and look for leaks, you wont have heat without enough collant in the engine to circulate under 13 psi closed system, check the resevoir for cracks and leaks mine fell apart over years good luck

Heavy antifreeze exhaust is coming out of my dash. Is there an easy fix?


The only way to fix that is to replace the heater core. The heater core is leaking coolant into the ventilation system. Heater core on this car can be a real pain in the rear so try and get somone to do it for you. It's about an 8 hour job and requires discharging the a/c systerm.

Appears antifreeze is leaking under the drivers foot area under the carpet. Are there lines that run between the carpet and the floor to the rear heater? This is a 2003 pontiac montana


There shouldn't be, it should just be the heater core near the blower motor. The tubes do run through the fire wall, so it may be a bad heater core

if your head gasket was bad it would most likely be overheating. your antifreeze usage could be from and intake manifold gasket leak which would cause it to use antifreeze but not overneat. the last possible thing i can think of is that there is a leaky hose that is just pooling up somewhere and not leaving puddles.

There is antifreeze leaking from the rear of my 2005 kia sedona. I I am not sure what it is leaking from but there is 2 hoses under there! Why would there be antifreeze in the rear of the van?


many vans have rear heater cores for added passenger comfort, so this is not unusual, it is very possiable either the hoses or there connections to the rear eater core are leaking or the heater core itself is leaking.
