What made you guys change your radiator? Just hopped in the G4 and got 'low coolant' warning....jumped out to find the level was out of sight so to speak.......popped to the local motorfactor shop and got a couple fo litre sof OAT fluid.....it took a litre to fill it to the cold fill line......no puddles on the driveway so I'm thinking rad leaking into autobox problem??

TBH, If you'd lost a whole litre into your auto box you'd be going no where. Either it's boiling off, or it's slowly leaking from one of many places including egr coolers, rear aircon (if fitted), the bleed screws over engine etc etc. Not saying your auto box cooler isn't porous, just that a full litre in the atf would have totally spannered the 'box.

Clive, I changed mine purely as a precaution - and it was very blocked with mud - down the sides where cleaning is almost impossible - or it was until I got a 90deg attachment for the jet wash which also has the advantage of reducing the direct pressure onto the rad, so it doesn't bend the fins :thumbright:

As Ben just said though, if you have had the pump replaced or even just the belts as the top hose has to be taken off the get the front cover off, so you will always loose some coolant, then a top up is not uncommon, though if they followed the correct bleeding procedure then it should have been pretty much full - though I think when I last had to re-fill mine after changing the front cover, it did take a day or so to get the level right.

As Dom says a ltr of coolant would have recked the box by now - it only takes a very small amount to screw the TC up.

I have a copper pipe setup at 90 degrees, but I can only push a hose on it. So with the poor pressure as it is, plus the 90 degree angle and squashed end for flattening the spray, it's got bugger all power!

How did you connect some form of angle onto a jet wash?

From what you guys have said, it's sounds like it's been border line low since the belts were done..... either that it an air lock that wasn't spotted by LR? Will keep checking it over the next few days and see what happens :thumbleft:

It's a optional bit that I bought for my Nilfisk jetwash - An example is on this page http://www.machinemart.co.uk/shop/range ... 10A5E1CA81" onclick="window.open(this.href);return false;

Its actually a Chassis washing thingy - and it works extremely well at that too :thumbright:

Dave, I did this but used 8mm copper for the last bit. Great pressure with hose on it :thumbright:
