This is because the coolant rubber line that comes in from above is not air tight seal. A lot of coolant evaporates out of the overfill tank.


I met a fellow at a car meet that showed me to wrap some black electric tape around the hose and jam it down into the overfill tank to make it "air tight". I don't have to refill my coolant as much anymore.

that was really helpful

will keep my eye on it , if i will refill that again i will do it

thx buddy!!!!!

that line is easily pull out by my hand after last trackday

saw some white spot in my engine bay
any better solution to fix it ?
a glue gun?
or a proper rub plug ?

here is the video for me last track day after all the part on

big improves

my next move is going to be a racing seat cause the oem seat can hold my well for now

The line shouldn't be difficult .. it's just to reduce the coolant evaporation by reducing the excess gap. I'm able to split mine out with some simple fidgeting.

I'm not sure what you mean by white spot.


I would not recommend a glue gun.
If you want to be fancy you can get a rubber grommet .. find the right diameter and fit it in there ..

any idea for find a rubber to do it ?

just measure the diameter of the tube and buy a rubber grommet at whatever hardware store of your choice
