another question could be related.. i no i have a little air in my radiator.. be cause when i rev my motor.. i can hear water sloshing.. where is the highest point in a suby.. any help is better than none.. lol ill take anything...

thanks in advance 4 any help..

How do you know you're losing water from the top of your radiator? I thought there was no cap on the radiator... the highest point should be the filler bottle mounted on the intake manifold.

yeah that wat i meant.. im loosing water from there..

check the front pass side of the plastic end tank on the radiator. They are prone to crack and the water leaks. Once the level gets below a certain point it stops leaking, but the system doesn't hold pressure, and you can get the sloshing water noise. Mine had that.

When you fill the system, you fill the filler bottle (on the intake manifold) to the top, and then you fill the overflow bottle (the one connected to the hose on the radiator cap's neck -- I think it's mounted to the radiator?) to the "full" mark, right?

You should lose coolant from the overflow bottle before you lose it from the rest of the system, I think. It should only actually get low in the system if you have a huge leak or if the overflow bottle is empty.

In any case, if you're losing coolant, you have some kind of leak somewhere... Sometimes you can find a coolant leak by pressurizing the cooling system with compressed air. Most shops have attachments that go on their air compressor and fit in place of the radiator cap for this specific purpose, so you might want to see if you can have the test done.

Also, check the hoses into and out of the radiator. I hadn't tightened mine enough and there was a slow, hard to detect leak, after replacing the radiator hoses.

i always keep the overflow full.. so im just loosing it from the other one.. had a look around today.. i did replace a pipe like 4 months ago when i just got it.. and there was a little bit of green around it eg inhibotor or how ever you spell it.. soo fingers crossed.. it was there.. will do a test to night to see if i loose water if out pressure... or wif pressure.. ect cant afford to go to the garage.. got my baby girl on the way.. soo gota watch the $.. grr petrol.. thanks 4 all the ideas..

LMAO...it sounds like you had the exact same thing happen as I did. I think the hose just came loose, or wasn't tightened enough when I replaced the hose. Either way, I hope that was it.
