No heat?

Hey there everyone, previous owner told me I might need a new heater core, and well I've been searching and have yet to even find one. Could this really be the problem of me having no heat in my legend? 1993 Acura Legend "LS" 4dr.

If your heater core was bad you would be losing coolant. The passenger floor board would be saturated with coolant. (and you would smell it).

Does the blower motor work? If it does more than likely your thermostat is stuck open. (Replace with one from Honda/Acura only)

Would it be expensive to replace or something I could do on my own?

New unit can be had for under 40.00. It takes me less than 15 mins to swap. (very DIY friendly) As long as you have basic tools, funnel, drain pan.

part #19301-P8E-a10
Sometimes you can find them on ebay for less.

There are other possible problems for not having heat.

1. The heater core is plugged up from years of gunk.
2. The valve to control the flow of hot coolant to the heater core could be broken closed and not allowing coolant to enter or the metal line going to it could be broken or just fallen off the valve causing no fluid to go to the heater core. Now if you find the metal line off then it may be off to keep a leaking heater core from leaking.

Replacing the heater core is a bigger job as it requires the dash to be removed, however if you do want to do it I do have a used heater core available for $70 shipped.

^ That's very true, however his description on what exactly is going on was vague. Tank you need to give more info what exactly is/isn't happening.

I turn on the heat, and NO hot air comes out, I have nice cold A/C but no hot air what so ever. No leaking of coolant as far as I know. Just no heat. Everything else is fine, except I need a new belt.

I was thinking of getting the radiator flushed, and then getting the thermostat, The original owner hasn't used the car since august and I've been using it for about 1 month now. I hope it isn't the heater core, but like BIGBOY said, I would see coolant in the car.

I know when I had this issue it was due to a stuck open thermostat. Does it take your car a long time to get to operating temperature? I hope the PO didn't remove the thermostat, people do that to prolong BHG issues.

--BUMP--

I went to a mechanic, and he told me that it could possibly have been removed to prevent over heating.. What's the chances that it'll over heat and blow? and how would I stop it?

So I spoke to the original owner, he said the smell of anti freeze was coming in the car, so his mechanic cut it off, and told him to replace the Heater Core
