Coolant Leak
#1

Hello all,
I have a problem with a coolant leak in my 2004 Super V8.
To cut a long story short, I drove a good 100miles in the car and it worked perfectly, arrived back home, started the car the next morning and "Engine Coolant Low" appeared on the dashboard, the car took 2l of coolant to be full again, no puddle underneath the car, I presume it emptied itself over the motorway, when the car was running at idle there appeared to be no leak, but as soon as it revved up there was a steady stream dripping down the front of the oil pan, but I can't for the life of me work out where it is coming from, is there anything around that area that is prone to leakage, heard about the valley pipe, hoping it's not that! Any ideas?

As its a 2004, have you ever replaced the coolant header tank ?
These are notorious for leaking where a small pipe enters at the top-rear. The plastic nipple gradually cracks until it completely fails and the coolant can then exit in quantity. It could also be the thermostat housing. I am not sure on this one, because my car is the V6 model so a bit different, but the header tank problem is common to both. Adding 2 litres is a lot of coolant, so you have a pretty obvious leak.

As above on my 2003 this went as well, smelt it for weeks and could never find it, until one day of investigation I saw a small amount of dry orange coolant that had dried on its way down, gave the pipe a wiggle and to my surprise it snapped off in my hand, the coolant had eaten away at the plastic. Cheap and simple fix of new coolant tank.
