Hello to all my fellow z400 riders...I am a proud owner of a 2 week old 06' z400 quad and had a ? about upgrading the radiator. Would getting a Fluidyne radiator help cool the engine down substantially from the stock one? Was looking at purchasing one for my stock z and was wondering if it was worth the $450. Thanks in advance.

here is the radiator im thinking about buying

 

I would change out the themostat first. By changing the radiator without the other, I don't see where it would help.

 

Saw this on ebay, might want to try that first.

Don't neccessarily aggree with the hp gain claimed, but it would run cooler.

 

I'd switch the coolant to Engine Ice first..... they claim it runs cooler and it seems it does for more people....

 

So I guess if I change the thermostat, radiator, and add the engine ice my z would be running really cool. [img]i/expressions/face-icon-small-smile.gif[/img]
