Hi All, would a stock coolant recovery system be useful? After a drive, can see underneath some coating of antifreeze on the chassis.
Any suggestions? Thanks
Banana out.
First make sure you don't have a leak somewhere; then check your radiator cap (they are cheap insurance) to make sure it is working properly e.g. holding system pressure as it is supposed to do. Auto parts stores do sell universal overflow (recovery) tanks though.
Thanks for you help

They're a good addition. Do you keep topping up the rad? They will usually stop overflowing when they reach a certain level.
For a non-recovery system, you don't fill the rad completely up to the top. There is usually a little flat "shelf" under the cap that indicates the fill level. That being said, it's not a bad idea to add one if you aren't concerned about looking stock.
There are no leaks, i do fill to correct level and have correct cap.
Thanks for the help, i will decide what to do
Not to :deadhorse: but correct cap because it is working properly; sealing properly?

Yes it is, i may be getting paranoid for nothing, thinking about it, could just be a small amount of antifreeze that comes out of the overflow tube
Thanks
You could just put the tube into a holding tank so it doesn't go on the floor. That way you have an idea how much is coming out of it.
True, thanks
While perhaps not being the most aesthetic, it wasn't un-common in the day to see, as a puke tank, a beer can with the overflow hose stuck in it. If you're going for Day 2 authenticity, that may be an option. :cheers:

Lets see...how many cars made in the last 40 + years don't have one ? The point of the recovery system is to keep air out of the cooling system.
When the coolant heats up and expands it goes into the tank. When the coolant cools down it gets sucked back into the radiator. The radiator is completely full at all times. Beer cans etc... were to keep coolant off the driveway, garage floor ( and mandatory if you went to a race track, coolant is slippery) etc... Regardless you need a properly functioning cap. A very common cause of overheating is a cap that does not hold pressure.
You can get a repop on ebay. https://www.ebay.com/itm/223335692273
Depending on how original you want/need to be I used this polished stainless recovery tank on my wife's Challenger.
I mounted it right next to the radiator and it works perfectly.

I added an aftermarket overflow tank to my car. Although I think they should have added a slight flare to the hose connection points . . . otherwise, I am pretty happy with mine so far.
Systems look great! Well done.

What does this statement mean?

:iagree: On the lack of a flare. My solution was to cut off the tube and drill out the bottom of the tank. Then I added a 6AN fitting in the bottom so I could run aluminum hard line up to the rad cap. The overflow tube is still in place on the bottom.

DUDE! that looks awesome.

Please, please, please consider getting rid of that glass fuel filter. IMO they should be illegal! They can break or rattle loose. A disaster waiting to happen! I know from personal experience. I'd just hate to read on here someday how you lost your car ( or worse!) to a fire. Metal ones are the safest . IMO plastic ones are also not a good idea.
Yes, have seen those stock ones for a 74, the overflow on my vehicle is on the passenger side which i can switch but, it gets too cramped in the battery area.
Thanks for the suggestion, am going with a universal stainless steel canister. Was suggested by another member. The emmision canister is gone so have the room.
Have a good day

Crap, my vehicle has one of those! Will change to metal when i get a chance.
Thanks for letting us know.

The OP's first question was would it be a good idea to have a recovery system. My point was YES. that is why they started to put them on at the factory starting in 1973-4. It helps to prevent coolant loss, overheating and cooling system corrosion.
That 74 recovery bracket is darn near priceless last time I looked. For a pinch I recommend the "beer can" method or the parts stores have retro fit bottles and brackets.
Agree that they are a good idea. I have to top off the one in the 73 every now and then.

Looks like you rather have the radiator filled up after it does its drain after a drive. At that point you don't need to fill it anymore. You would be at the sweet spot to stop filling it. For me, just getting a can for the overflow just prevents spill on the street. Then you still need to fill the radiator. For piece of mind, just get that stock appearing recovery system, then the radiator will be full all the time and no puking.
On my 70 Cuda, I copied someone's system using the windshield washer tank as a recovery system. It works just like a normal recovery system and you can't tell I have one. Unless you look at the tank and see green fluid. My radiator is full all the time.
One of the first mods I did years ago was a coolant recovery tank. Got tired of the constant spot and people telling me I had a leak. I fabbed a bracket an set the tank next to the radiator. I highly recommend it, its not had to do. I got pics somewhere I can post if anyone is interested :wrenching:

If you want the factory setup.

That picture was from some time ago . . . I no longer have any of the glass style filters. :bradsthumb:
