I'm loosing about 1/2 pint of water from the T350 every time the car get up to pressure.

It's a gradual leak and the only time I see any pooling is after the car has cooled down and it's left in the garage.

Having said this there are unusual factors the water is not in my OIL. The spillage is not 1/2 A PINT,the pooling occurs at the back of the car on the garage floor!!!!!!!!!!!

Cold it be a heater or sensor or even a cor plug????

any ideas welcome!

Not sure I can help on this one, not got under my Sagaris yet but you say its at the 'back of the car' - therefore is not under the engine?

Are you sure its not running downhill to that point?

I`m not sure of why any coolant would be near the back.

I'm fairly confident it's tracking from some where just trying to figure out were it could leak from and run down to the back???

with that amount of water it could only be coolant unless you have a cat coming into your garage for a piss.

I was loosing about exactly the same amount of coolant when I got the Sag as I was over filling the car as it said in the manual. I also had a dodgy filler cap, never have leaking water anymore so it is worth checking these points again.

My Sagaris always spits out coolant when I overfill it, people say fill it near the stop but it always re-adjusts itself to the same level after a short drive - stays at that level til the next week (and I top it up again) - therefore I don`t top it up as much..

Must admit I thought I might be topping it up too much I fill it so I can feel the water is about an Inch from the top.
Problem is the expansion tank in the T350 is right at the front close to the bonnet and real bh to reach.

But still can't understand why the pool apears under the back axel!!!!!!!!

That's too high, it needs more air for expansion when hot and .... you need a dipstick!

The correct level is just next to the bottom of the pipe from the engine, about 3" lower. I've had to work through a number of adjustments to the cooling system this year as we sorted out some other problems; so I suggest you try it at that level for a long run.

It would have to be much lower to cause problems (ie sucking air into system). smile

I agree with Tail Slide, when I fill it near to the top it just spits out a load when it gets hot. Usually at traffic lights with people watching....

I found that the manual is very misleading as to the correct coolant level. I initially filled the coolant to the recommended level stated in the manual and had the coolant spilling out all over the place. The coolant cap is designed to expell coolant when filled to high, so it was a case of trial and error in finding the right coolant level. Now I use a wooden spoon marked out with the correct level for my engine and keep the coolant filled up to this mark.

Its a on-way valve inside the cap that goes on the water reservor, on the Sagaris this is blue.

weird it's at the back of the car, the only time i have seen liquid at the back of the car, was when i filled it right up with petrol and then left it idling for about 10 mins (dumb thing to do, got into a detailed chat with someone and should've switched her off). The petrol expanded and started leaking all of over the floor - was the first weekend i had it, thought something major had happened. I don't put too much in now (35/40litres), would rather stop frequently and fill up than get stuck in traffic and have it leaking.

The expansion tank levels out after a while, i used to top mine up way to high, but it's found it's own level about an inch from the bottom now. (this is the expansion tank, which i believe is the updated version, just right of the airbox, big blue cap).

Also had a bit of a water leak a few months ago, it was one of the pipes, just needed a new grip.

probably best to ask in the Cerb section about the 4.5...

For this topic, I have recently cured mine - a case of losening , refitting, and retightening the junilee clips on the front nearside. Bingo!

Wait until lady of the house is out. Enter kitchen. Open utensils drawer. Borrow wooden spoon. Stick thin end of spoon into coolant. Remove and measure against the side of the 'tower'. Your choice whether to return the spoon or not.

I agree with Tailslide - just over half way full, on mine the coolant level liked to be just at the top of the side outlet pipe.

I use a wooden spoon from the kitchen with a notch cut in it!! (no expansion tank on my tam). Garage is flat so easy to mark level (guestimate from top of tank to the hose that goes into the engine. - Just pop it in the tank and measure the wet level on the spoon.

PS don't tell the missus what I use her spoon for....
