2G Radiator Overflow replacement

[ileagleracing]

I want to relocate my radiator overflow tank and I wanted to use this: http://www.ebay.com/bhp/radiator-overflow-tank-universal
Am I going to run into problems because there is no dump tube like the OEM tank?

As long as it has a vent hole it will be fine.

I bought one of those mistakenly and I don't think it has any vent hole. I can confirm tonight.

You can always drill a tiny hole in the cap if it doesnt have one.

It has no vent hole, but I do have a drill.

if it sucks it from the bottom sure, will be fine but they not the best even then, I had a friend buy a mishimoto one and that had a small vent hold and it was forever over flowing and weeping out the hole,

if it has a top burp hole for the excess to overflow from then a hole is not needed as that is the vent/breather hole so your good,

when i clicked on the link it showed me a few so unsure on which one you are actually looking at

The line to the thermostat housing is from the bottom of the overflow tank, so if I add a hole (or weld a bung for a drain line) near the top of the cylinder it should function like factory?

I'm coincidentally using the metal one below what you're mentioning and I guess I'm happy with it.

Yes thats correct, as long as the overflow is near the top it will retain the coolant until its needed again as that takes it from the bottom, essentually having a closed system like that is better as you get less air drawn in, or so i am lead to believe, as in theory its just sucking in ll fluid and not fluid/air from the oem setup, how true this is i dont honestly know but seems ok in my head ,

Vent are usually traditionally drilled into the fill cap of the reservoir.
