I see the resemblance.

My goal for this weekend is to finish ripping the interior out of Lucy and see if the heater core is actually leaking. Carpet is ruined for sure - hence the need to yank everything out in the first place.

I'm thinking of swapping out radios. I have a rebuilt Delco AM/FM unit n Lucy now - tied to a CD changer. I am thinking of going to either a Custom Autosound or a Retrosound unit. I want to be able to play tunes from my cell and go hands free with the phone. Just wondering if anyone has had good or bad experience with either. I definitely am not looking to cut up the dash and I want as near-stock appearing as I can. Thoughts anyone?

Hay Frosty, i bought a custom autosound from ecklers a few years back for one of my 57 chevys, work ok, just seamed a little cheap in its finish with the chrome 

 but i did like its usb port it had, think it was on the rear too so you can hook it to your cd player. and hide the wire

i like old school and have tape players in all but one of my toys, wife goes off at me for playing all my old 70 and 80's stuff ! haha🙄

One of the auto mechanics I follow on YouTube (met the guy IRL a few years  back - his shop is literally next door to Kings Island in OH) rebuilt his dad's hand-me-down '90's Silverado and he put a Retrosound unit in the truck. If interested, here's a video he did about the unit - https://www.youtube.com/watch?v=JnTdEagU7VE.

Stewy - I did watch your guy's truck video installation this morning on YouTube. Thank you for the referral. I would have liked to see him actually road test it and all. Any idea how much he likes it? Sounds like he was a lot "meh" after it was installed.

 

Hey, @Frosty - happy to help (even if it is only a little). I have done some searching on EricTheCarGuy's website as well as his YouTube channel however I have not been able to find a video / post where he gives the pros and cons of the radio and if he would recommend the Retorsound over, say, the Autosound brand.

 

That said, I did send Eric an email asking if he did, in fact, provide his thoughts after using the radio for a while and, if not, if he would reply back to the email with his pros / cons / etc. (I'll keep you posted if / when he replies). I have also found, on his website, a video he did of installing the radio and starting around the 29:11 time stamp, you see the radio power up and he goes on to give some likes / dislikes of the radio (however nothing in depth). To see that video (and I apologize for not being able to link directly to it but the way it's embedded in his website made it fairly difficult), follow this link and click on the video I have highlighted below:

I know Kiwi. What irks me the most is I asked the shop I had it towed to last fall when the belt first came off to look at it and see it if was leaking. They didn’t. They just fixed the belt and didn’t look at the puddles in the passenger foot wells. This is the same shop that doesn’t know how to fix a convertible top.

I feel for you buddy! Been there do that, only in a stone driveway and no convertible! You are right, it's ugly!

How old is the core? & Quick question, what kind of anti-freeze do you use?

As far as I know, it's the original heater core - so its about 48 years old.

I use a 50/50 mix of Prestone and water (green stuff).

Hey @Frosty - I received a response from Eric (see below). When he says "radios" (plural) he has two units - one in a Ford Fairmont build he did and the other in the Chevrolet truck build.

 

Quote

A review on those radios would be a nice addition. I just need to find the time to shoot it. 

 

I’ll summarize it like this. My experience hasn’t been that great. It hasn’t been bad either. I like they way both radios look, but the sound is just adequate. If you really want it to sound good hook it up to an amp and run a sub. I also don’t like the controls. It takes a bit to get into the menus to make adjustments. Because of the limited buttons this can be problematic at times. 

 

I hope that’s helpful. 

 

Eric

 

Hopefully that lends at least a little help / insight into making your decision.

Well, I’d say you got your money’s worth out of it! I figured you didn’t use Dex-cool, but you never know! That s- - t is bad stuff!

Yeah, it doesn’t owe me anything Last Indian. However if (big if I know) it is fixable I’d prefer to do that than buy a new one. I’m told the quality of the metal of the original is far superior to any of the reproductions. 
 

I’m not a Dex-Cool fan. I’d only use it if that is what is recommended for the car. I’ve seen and read too many problems to switch at this point.

I'm toying with the idea of fixing it myself. I'm just wondering how huge a headache it will be for me - time wise. First thing I need to do is plug up the two engine hoses to/from the engine so I don't continue to lose more coolant. Then I can get serious about disassembly everything else. Of course I can only work on it on decent days too.

I've thought of that. I just need to use some sort of tube to connect the two ends and clamp them down. I just haven't spent anytime noodling how big a diameter tube I need. I admit I'm lazy at times.

Well I worked on Lucy again today. First thing I did was disconnect the hoses going to and from the heater core. Wouldn't you know that they are different input and output hoses. Input from the cylinder heat to the heater core is 3/8" and output to the water pump is 5/16".  The output hose was absolute bear to get loose. I ended up cutting it at the firewall/nozzle. I then disconnected the entire input hose from the firewall and cylinder head and routed the output hose to the cylinder - as Kiwi suggested. This simple swap took almost 45 minutes fighting with those two damn hoses.

IMG_7162.thumb.JPG.bfdaaa59e924c7de6fa0bd5fee61acd9.JPG

Nice and snug trying to get your hand in between the hood, the AC cover, and on the hoses. Greeeeaaaat piece of engineering.

IMG_4933.thumb.JPG.c6899febfbf43d5595c44bd86d9fb6e3.JPG

The AC / heater core unit from under the dash. Surprising only three nuts and one screw hold this sucker to the firewall.

IMG_4937.thumb.JPG.93fb3f914f13ada7fb994c02bfe2bb27.JPG

The shop manual tells you to mark three cable positions when removing the cable that goes to the dash so you can re-align it later.

Welll - the damn thing is out. I didn't even have to remove the fender or the inner fender.

IMG_7173.thumb.JPG.f79745beeffca222ac0c226cf7e09a7a.JPG

Could they have made this any more f*cking complicated? I spent over an hour trying to figure out how to remove the heater core from the box. Nothing in the shop manual about it. I am on the verge of breaking the fiberglass housing! You know that bracket that I marked with the 3 alignment settings, turns out it's three mount screws secures the heater core to the housing shell, so that how thing on top has to come. Sonofa....

Yes, this mofo is apart!  Happy dance time!

Here is what the heater core looks like.......

Now the most interesting thing to me was.....this was NOT an original Harrison Radiator unit! There is no name on this thing at all. This means the heater core has been replaced before! Now I am thinking I should seriously overall the HVAC system on this car since I have it torn apart this far.

The AC has never worked on this car since I bought it over 25 years - but hey it's a convertible - who needs air? You need AC in bumper-to-bumper traffic on I-75 waiting out accident with 95+ degree heat and rain outside CIncinnati with 6 more hours to go. Not often, but when your family is in the car....and you don't have air - you are a walking dead man. Just saying.....

Since this is not original, I think I will just purchase a new core rather than have it rebuilt. If it rains Sunday or Tuesday, I might be making a road trip to National Parts Depot.

I ordered new carpet, and some interior parts from Legendary Auto Interiors. It said it would be 3-6 weeks before I get it.

 

Well done frosty! those hoses are really good at welding them selves to the metal connections and remember what you told me about old fuel hoses?

 i recon same applies to heater hoses too!! replace the lot.

good on you for doing this job your self, if you had a shop do it they would charge you a arm and a leg to do just what you went through :cheers: 

AND you will know exactly what you have fitted.

i also agree, if you had a original core in hand to take it and have it rebuilt but since its an after market one, just replace it full stop :bacon:

i wonder why the different pipe sizes to the core???? 

to reduce flow rate and allow for more heat absorption ????

Replacing the hoses is probably not a bad idea. My only reluctance in replacing the output hose to the water pump. It means I have the added hassle of having to drain the radiator and the water pump and the opportunity to make a bigger mess of the driveway. I ended up putting almost a gallon of antifreeze into Lucy last night after I was done. I knew I was low (obviously) but not that low. 

Your theory on the different hose sizes are as good as any I can think of.

Today is suppose to be nice, so I think I will drag out the Roadmonster, exercise her, and work in it some more. Monday is a holiday, so I will do my parts run on Tuesday since it is suppose to rain then.
