Took your idea for my 55 plymouth with 6volt positive ground... Clutch does engage on 6 volts.. I put 12 volt batteries in the trunk and put an evaporator just under package tray and have rear vents from package tray.. Condensor is mounted under the car.. Hoses rand underneath.. Just not cooling as much as I would like.. Probably 55 to 60 degrees from vents.. On a 95 degree day... Wondering if the distance is the issue...
@@jonathanhermis1929 sounds good! I don’t think the distance would make a difference. Some things to consider might be compressor size, greater displacement seems best. Does the evaporator pull air from inside the car (like recirculate) and not hot air from the trunk? Heat transfer of the condenser is also critical, bigger is better with as much airflow as possible.
@@rustyoldchevy1149 I figured out the issue.. I called vintage air and they told me to only put 24 to 28 ounces of freon into the system... They said 200PSI on the high side is about where i need to be and 26 psi on the low side.. My problem is I had it overfilled. I was making the mistake of reading the charts online. Vintage air said Sanden type compressor are completely different than factory compressors.. And the charts online or most of them are for factory compressors.. And he was right.. I removed freon and brought it down to 200 psi high side and 26 low side.. COLD AIR NOW.... However my clutch fried. Makes a grinding noise when it engages.. If I let the system cool down for about an hour and recrank the car and turn system on it will engage.. Turn it off to simulate a clutch turning on and off or cycling it immediately starts grinding and wont lock in place.. So I either have a bad clutch or the clutch doesn't like 6 volts.. I have a 6v to 12v module I use for my 8 track player.. Temporarily ran it to the clutch and fed it 12 volts and still grinds and wont engage... So I am wondering if the clutch doesn't like 6 volts or am I ok to swap out and still use 6 volts.. Would hate for this to happen again and I loose freon lol...
@@rustyoldchevy1149 Also I cannot find anymore of those 6v positive ground to 12v adapters... Mine is a little silver box I bought off of ebay a few years back.. Cannot find anyone who sells them anymore... Would be nice to have a spare one... If you saw this system I have its a frankenstein unit... I bought a regular evaporator with 4 2" outputs on the front, the standard one you see on amazon for retros.. Mounted that on a piece of wood and mouting it just below my package tray in the trunk.. Made a package tray with 2 of the vents vintage air sells for rear air vent louvers.. Ran flexible hoses from the evaporator to (4) bilge blowers to push more air forward.. Ran the power to these bilge blowers through a variable motor controller to adjust the speed and ran the wiring up front under the dash adjacent to my temp/on/off switch for the evaporator.. But before it gets to the variable speed controller its ran through a 40 amp 12volt relay to handle the amperage load.. Fused of course.. Essentially your normal green wire that comes out of the evap to trigger your clutch or condensor fan is ran through the pressure switch and powers three relays.. One for the ac clutch to trigger the 6 volts to the clutch, one for the condensor fan, and one for the pusher/bilge blowers.. The 12 volt side is ran off of lithium phosphate batteries...All of this you gave me from your idea of making this work with 6 volt positive ground and I just went from there.. Appreciate the guidance.....
@@jonathanhermis1929 ok might check the air gap on the compressor clutch and be sure it’s in spec. Other than that the Charging system might not be 100% and a 6 volt alternator is the way I would have gone if I could have with my Nash.
@@rustyoldchevy1149I checked the air gap it’s within sanden specs. Replaced the compressor and bought a 6v to 12v step up transformer and it works thankfully since the clutch is just a coil. Just not cooling like it should. I am wondering if heat transfer might be my problem. Everything I am doing is in my Texas garage and it’s 104 in here with the fan blowing. Unfortunately the only spot to mount the compressor was coming off of the alternator bracket and that alternator bracket is attached to the lower manifold. Yes not sure why Plymouth/mopar did that back in the day. After running for awhile the heat does transfer from manifold to alternator and the compressor through the medal. However I see these are designed to run in high heat so not sure that’s a problem. Just scratching my head on this one. I am using a parallel flow confessor that’s mounted underneath the car slightly tilted. Maybe that’s causing a restriction. However I do see flow and stream through the drier sight glass. System has been flushed. There is enough oil in system. I noticed you did say recirculated air to evaporator in trunk. I do have a vent I cut in through the package tray. It’s not connected to the evaporator but just pulling some air from inside the cabin to the trunk. Yeah I thought about that too. Warm trunk air pulling through the evaporator. Maybe this is why the trunk systems are not as common as the front mount ones. Only reason I went this route is because I have the from air vent louver in the center underneath dashboard and my 8 track player. Just hate modifying original. Maybe driving at highway speed will create enough airflow underneath and through motor to cool things down. I must say though it’s only blowing around 60 through the rear air vents and it’s 90 in the car. Just doesn’t seem correct even at idle. I give up lol. I have three other classics I have systems on and no issues on those.
I've never understood why people think 6-volt is such a bad thing. And to work on something that someone converted to 12-volt from 6, is a nightmare! Just leave it alone and the 6-volt works fine. My '49 Studebaker truck starts up just fine when its -14°, which generally happens often in a Indiana winter. Great video! 👍
Interesting how the auto industry went from aerodynamic to square boxes Then made its way back to aerodynamic. Difference now is cars are lighter and boring.
Nash made some of the coolest cars. If you want to see the ultimate, look up Nash Ambassador Brougham. It has two "theatre" seats in the rear that are like armchairs, turned slightly inward to each other. Fantastic!
My dad had a 65 69 and a 74 I sure miss him taking of at the lights on everyone with that torque monster the 69 would burn rubber foe a straight block until he got out of it.
How many miles does this old gal have on it? And how many would you expect to get on that old straight 6? Wondering what the reliability of these cars was if they were well maintained considering how dead simple that engine looks
This one has a bit over 60,000 miles. As a general rule with cars this old I would expect 100,000 before a rebuild, but oils have improved dramatically since then so a rebuild would likely last longer now.
The passenger side is likely starved for oil due to the timing chain tensioner gasket blowout. Recommend replacing tensioners and upgrading oil pump along with rollers.
Thats defintly a Oldsmobile. The only car that can set 20 years and fire right up at the turn of a key i bought an olds that sat in a field so damn long weeds were growing out the hood. Tossed a fresh battery in it turned the key and that sonbitch fired rught up. The fan turned on and chewed up a huge horse weed that grew through the hood. Drove out the bushes and off to my house. Got home cleaned the hens nest out the back seat and got about 5000 miles outta her before the block cracked. Paid 60 bucks for it.
I was born in December of 1955 and have always Loved these old Nash cars ! Even though longevity runs in my family my Grandfather on my Mom's side past away when I was young and he Loved Nash cars and later Ramblers. As a successful business man in Worthington Mn he had a Chrysler Imperial for his primary car and a Nash or a Rambler for the around town errand car. In fact my Grandmother when I got my driver's license gave me my first car her 1960 Rambler. It was so much Fun, straight six with a three on the tree ! I somehow got the Nash and Rambler bug at an early age. I'm now ready to retire and am Blessed to be in a financial position to start acquiring affordable Classic vehicles, and a Nash or Rambler is high in my list. I think to start off I'm ready for the most lovable Nash in my opinion the Metropolitan ! I would Love to own an Airflyte and yes my 1960 Rambler as well. Thank you for reading and I will let you know when I buy my first Nash or Rambler !
She actually has some pretty good get up and go for it is . I love old cars I haven't bought a new car sense the early 90's they cost a fortune and are made so cheaply like a new house.
OH AND EVEN THOUGH IT NEED'S AN ADJUSTMENT IT SHO IS A SMOTH RUNNIN LIL BUGGER JUST AS SLIK AS CAN B SMOOOOTH SOUNDS LIKE IT'S RUNNIN AROUND 600 RPM MABY A BIT LESS NOTHING RUNS SMOOTHER THAN A WELL KEPT FLATTY
I CAN HEAR ONE OF THEM TALKIN A BIT A BIT OF AN AWKWARD REACH TO GET INTO BUT DOOABLE IN ANY CASE LUV A FLATHEAD BETTER LIVING THROUGH LOW COMPRESSION 😉👍👍👍
Mine makes the same noise followers seemed fine and lifters were stuck in the up position.. replaced all three in cyl 8, and waiting on new cam set screws to finally see if this fixes my problem.
