2011 Heater Core $1240 - Part B714300Q0A PTC - Alternatives?

Tue Jan 03, 2017 1:23 pm

Ouch.
The 2011 Used Leaf with 20,000 mikes seemed like such a bargain.
After a few months, the heater has given out. The shop just called to say the heater core is bad, and it's a $1240 part plus $1100-$1400 labor.
The dealer gave more or less the same price. The dealer says no service bulletin exists for any sort of discount.

Are there alternatives? At this point this is a $7000-$9000 car.
2011 Heater Core $1240 :o - Nissan Part B714300Q0A or B7143-00Q0H

--------------------------------------------------------
Are the failures of this part likely to be the temperature sensor, or the actual ceramic restive heating element?

This was a common failure among 2011/2012 Leafs; the price sounded low until I see that doesn't include labor.

http://car-part.com/ + independent shop could save you some $$$. Or not. The risk being you pick a wrong part or the shop messes something up.

There were a number of failures on 2013 resistance heaters (first year of dry ceramic type), but I think the hot water tank heaters on the 2011/2012 models were pretty reliable (although slower to heat). Is the shop certain that it is the heating element assembly (water tank) and not a control, sensor, or water pump issue?

As far as I can tell, they think it's the sensor element embedded in the heater core assembly referenced above.

The liquid temperature sensor is in the hose external to the water heater module. I was not aware of internal sensor(s). The labor charge noted in your original post seems really high because the heater is readily accessible under the hood near the 12-volt battery. The price for the part online at Nissan USA is $1175 so the shop's price probably includes shipping.

There's one here:

$275

or http://car-part.com

search on the vehicle heater core and there are many.

That's some spendy labor although I'm not sure how big a job it is. For that kind of money I'd find out.

For $2500, I'm willing to do a lot of shivering. I used to ride in an old VW bus that seemed to defy the laws of physics and actually be colder inside the vehicle than outside. The saying in the old days was "A beater with a heater," now the heater is half the price of the entire car? :shock:

If it isn't leaking, I could never see any justification for putting $2500 to fix it, even doing the work myself and a $1250 part I'd never do it, let Nissan keep their overpriced heater. You really can't get one from a junkyard either since there is no telling when that one will go out. I'm wondering if mine in my 2011 LEAF works, as I never use it here in Florida.

It seems though that GerryAZ may have something worth trying if you can actually replace the external temperature sensor for a reasonable amount of time and money. Otherwise maybe it is possible to modify it (at your own risk of course) with some wiring and a switch to override the temperature sensor and force the heater to work?

Hold on there... The heater core is the equivalent (and reverse) of the radiator... That is not a moving/ operating part, it is just a box that lets coolant pass through... If there is no heat, then there is a problem with the antifreeze circulation through the core.

Before doing a job like that, (which the mechanics would love to do), check the condition of the antifreeze. It could be considered to be relatively old. Also, someone may have put some additive that clogged the tubing of the core.

If the antifreeze level is good, and there are no leaks, then I would first flush the old antifreeze, run the heater with water and cooling system flush, and then "reverse flush" the cooling system with a garden hose to push out anything clogging the core..

I have had cars with NO HEAT and gotten great results with reverse flushing the heater with a hose. And it is a simple thing you can do in your driveway..

If that doesn't work, then start checking if there is an electric coolant pump that circulates the antifreeze. I have a Ford Escape Hybrid that had a recall with failing electric cooling pumps, which I had changed under warrantee. THAT could be the weak point in the system because it is an electrical moving motor that can fail over time.....

Good Luck..

I wouldn't be scared at all to buy a junkyard one. Typically you get a 90 warranty from a junkyard. New from dealer is 12 months. Could it fail? Sure. For a sixth the price I'll take my chances. The new one can fail in 13 months. I've bought engines, transmissions, electrical components, a/c components, all kinds of things over the years and have yet to have one fail or be bad. Sure it's possible but in my experience not very likely. Coolant maybe but it only has 20000 miles. Maybe the circulation pump but I'm assuming it was properly diagnosed. Certainly possible for a electric resistance heater to fail, it's not just a conventional heater core where circulation and leaks are the only things preventing it from working. Sensors, switches, the wiring and even the element itself can all fail.
