Does anyone know the steps involved in removing the heater core? The dealer shows it as like a 10 hour job. But I heard you can see the core if you remove the glove box door. I cant find a manual in any auto parts store to save my life. Can someone tell me what all needs to be removed in order to get it out so I can decide if I want to do it myself. I'm handy with tools and all, I just wont bother if I have to remove the whole dash or something nuts.
For the past couple days, whenever I wake up in the morning there's a puddle of coolant under my car, and I just took it now to the mechanic and he tells me there's no leak in the coolant... I don't get it. I know it's coolant, but he checked and says there's no leak. It's on the driver's side, sorta under the engine. When I got under the car, I saw coolant dripping off one of the hoses, and also off the petcock, so now I'm trying to figure out if it's one of the hoses that's leaking, or the water pump, or if it's the heater core itself.
Another thing, whenever I turn on the heater, there's a coolant smell in the car after about 2-3min. I've researched it and I guess there might be a leak in the heater core itself, but could anyone give me any ideas on what to look for? Obviously the mechanics around my area aren't the most savvy and I really hate wasting money for stupidity.
One thing you might check is the HCV, the heater control value leaks onto the hot engine and the steam rises and is suck in by the fresh air vent and goes into the car, this is what happen to me, the HCV is located to the rear of the engine, top just under the firewall, follow the hose's that comes out of the overflow/reserve tank, one will go into the firewall and the other one will go to the HCV, to test this, turn your car on and put you heater on high, look under the hood to see if you can see steam from the rear top of you engine, if not, then turn your car off, wait a few minutes and follow the hose to the HCV and grab it, if it's wet, than it's leaking, it's hard to reach back there but I did it and solve my problem
oh, unless there's coolant on your floor in the car then's there's no leak inside, what you smell is steam coolant that is being suck in from outside thu your fresh air vent
If the coolant is dripping off the petcock of the radiator, chances are that there is a crack in the plastic end tank of the radiator. Check around where the hose from the engine goes into the radiator on the driver's side.
