Coolant tank on D1's and RRC's - Land Rovers Only

When it says "Fill to level when cold" by level does it mean
All the way to the top?
To the top of that + inside?
???

There should be a "Fill to here" line even though the reservoir is not see thru....

I fill mine half way - i cant see any line but like said above the coolant needs to go somewhere and if the tank is full ur gonna blow a gasket or seal somewhere

Don't worry about over filling, if you put in too much it will throw off a little over the next day or two of driving, they alway seek their own levels.

thats what i thought, preciate the info.

Mike is correct. If you overfill it, the excess will just be forced out via the pressure relief cap. It's more important that it be ahowing in the tank when cold, because that's the least volume the liquid will assume. If it is too low, as the coolant cools off, the level in the tank will go dry and you will end up with air in the system. Too much won't blow any gaskets, the cap lifts well before that. Keep in mind, air in the tank is compressable, water is not, so if the tank had a higher level, the level will rise till it cannot gofurther, and any increase in pressure just lifts the cap enough to release the expanding volume.
