If i see a little bit of steam on my window while driving and my vents have the slight smell of coolant, is it for sure my heatercore?

I really can't afford a new one, especially with labor.. does anybody know where i can find a cheap aftermarket one?

Are they as much of a pain to install as everyone seems to say??

thanks guys.

sounds like the core is on it's way out. as far as buying a new core I would say, buy it from a local radiator shop just in case of a warranty issue.

If you don't need heat, you can simply bypass the heater core from under the hood. The hoses going in and out of the core can be spliced together.

Ok, as Tech just stated, if you dont care about having a heater in the car, or if you just dont have time to do the whole procedure, just look at the hoses going from the motor to the heater core, and just get a hose slightly longer than you need, and just connect the two pipes coming from the motor together.

If you show your BMW love, she will love you in return.

I do need my heat and my defroster, but until i can afford it i guess bypassing it is better than smelling coolant , which can't be too healthy. Only problem is , my heater core has 3 hoses...? im not too sure if thats normal. lol

You should be able to get a new heater core from an aftermarket resource for under $175. They're a PITA to replace, but it should fix the problem.

BTW, I'm getting the same sweet smell in my car, but I hope that it is from where I might have spilled some coolant down in there while replacing the secondary water pump.
