Radiator overflow
Hey guys,
I'm plumbing my coolant setup on my ls1 swap, and was wondering what everybody is doing for a overflow setup? I'm using my stock radiator, can I just run the overflow hose to a overflow tank? thanks Posted via Mobile Device |
Re: Radiator overflow
Yep, you can put anything in there you wish.
I just left my overflow hose open on my LS swap as that's how GM built the truck anyway. |
Re: Radiator overflow
okay. that sounds great. thanks
i may just leave mine open also, any issues at all with this setup? Posted via Mobile Device |
Re: Radiator overflow
No issues for the overflow, millions of cars made that way.
Environmentalists may not like though :lol: If you fill the radiator to the very top,,, It will drip (usually after you shut it down) and basically level itself off to a point where it stops doing it. And you are good to go. An overflow however isn't a bad idea and having a closed cooling system can have some advantages. There are many aftermarket and factory style tanks that should fit your taste. A neat way to do the 67-72 trucks (and I've been thinking about doing it myself) is to take another washer bottle and bracket that is used for the washer/wiper system and mount one on the other fender (passenger side) for an overflow. You just have to change the cap to a dual nipple design. One for the radiator hose and the other is your drain or vent. Doing it this way on a 67-72 truck makes it appear like it's a factory setup... |

Re: Radiator overflow
If you run an open system, whatever you do, don't put Dexcool in it. When it mixes with air it turns to mud. Personally I never use it though, its crap in my book.

Re: Radiator overflow
^this. Dexcool was a bad try at an environmentally friendly coolant....great until it turns to algea in your tank.
Get the green regular, or the Pink Universal....or you can be gangster like me and just run water and water wetter. |
Re: Radiator overflow
I have my overflow into a old brake fluid bottle...stays empty!

Re: Radiator overflow

Re: Radiator overflow
I've always just ran my overflow through the inner fender. When I teched in for the GG autocross, they told me I had to have a catch can, so I sucked down a Mtn Dew as fast as I could, then used a mini-bungee cord to tie the can to the bumber bracket under the fender. :lol: He said as long as it didn't fall off, it would be fine. It stayed on there, too. :burnout:
I'm thinking of having a custom one made to fit under the inner fender, so it's out of the way, but more than likely mount one under the battery tray. |
Re: Radiator overflow
If you are ever going to take it to a race track they will insist you have an overflow tank.
