It seem every now and then I have my radiator hose overflow hose leak a good amount of coolant I assume this isn't normal??? is there supposed to be a recovery tank on this unit? I have had this jeep about a month and it seems like if it's not one thing it's another...I just changed out the water pump and the thermostat now this 74" cj5 304
Real purpose simply being keeping your radiator full regardless of the temperature(aside from the environmental aspect). Heat in materials (coolant in this case) causes the materials to expand. In the case of the radiator this is pushing the extra fluid that will not fit anymore in the radiator because it has expanded out the tube. If you have a resevoir then when the radiator cools it will suck the fluid back into the radiator and keeps it full. They are cheap to pick up and will keep you from having to fill your radiator every so often and will keep a toxic substance from leaking out.
Also note the anitfreeze/water mix is poision for dogs, cats, animals. Just a tablespoon or two will kill most dogs. You have 2-3 hrs to get to the vet before its too late. Smells sweet and they will lick it righ up. So antifreeze is not a good thing to spill around the house.
You also have to insure your radiator cap is compatible with a recovery tank. Early caps only sealed on the inside of the filler neck. Later recovery caps have a rubber seal on the inside and the top as well. The early caps are becoming hard to find due to being replaced, however, if yours has one, the tank won't work.
also the recovery tank is needed in some area's, state parks and such to avoid environmental damage. Nothing a zip tied Gatorade bottle to the grill won't handle. I installed one on a 76 just because of the previously mentioned fact.
not tryin to thread jack but i am having the same problem i am about to put a water pump on but i didnt think it was bad but it puts out steaming radiator fluid from the hose every time i take it out not fun sprayin fluid as i go think it could just need a bottle or does it sound like a pump thanks
If you get stuck it better be broke or you didnt hit it hard enough
I have always been under the impression that besides the obvious environmental reasons that a full coolant system maintains a higher boiling point due to the lack of air and proper rad cap for pressure. So you might see a little better operating temps as well due to the fact that your system will now be full all the time.
its actually the pressurization of the system that raises the boiling temp. it works out to be ~3 degrees per PSI. certainly works better with a full system, not to mention ill keep you from overheating when its full
