Coolant Loss

Evening guys,

Have an issue with coolant loss. Freelander 2 2.2 Diesel, 2010 with roughly 125k on the clock.

No externals leaks, mechanic has been all over the engine bay and there is no evidence of leaking what so ever. Pressure test when cold and hot, no pressure loss.

No mayo in the engine, oil level doesn't appear to be increasing, she is holding a steady temperature.

Open to suggestions as to what else to try? Any ideas on what to do and check?

How much coolant is it loosing?

Has the pressure cap been replaced, as a matter of course? 2009 Rimini Red SE TD4. My daily driver.

She's gone from Max to "low coolant level" indicator in a couple of hundred miles.

I've replenished the coolant back to max and I'm going to take her out for a long run tomorrow to see is it drops again. (One option is whether the previous owner(s) ran her to low and when I was "refilling" I trapped air in the system which has now bled through) so I'll get a measure.

Plus I will recheck the oil again and see if the level increases.

Why replace the cap...is there something relevant to the cap?

It can take some time to get all the air out of an empty or partially emptied system. My own TD4 needed a couple of top ups, after I rebuilt the engine. 2009 Rimini Red SE TD4. My daily driver.

Hello Hoopyfrood, With reference to your coolant loss I have experienced the same over the years including the fl2s early months when took delivery, every service upto 105000 I have always complained about coolant loss, the dealer although hopeless couldn’t find or locate the leak, well same miles as yours it must be going somewhere until the day I bucked up courage and replaced the cambelt and water pump. Found my coolant loss at the water pump, not sure what the item is but the pump casing has a sort of core plug, not the drain plug but this plug,as it’s pressed into the case and it’s tight. It’s a pity as only a month ago I binned the pump as I could have shown you. Anyway the plug showed a leak and quite a leak too, where the leak was in relation to the crankcase as coolant always leaves a trail there was a clear path of white dust/line behind the crankshaft pulley but not near it for it to fling into view.

So if you have done everything you can think of I would say it’s this plug on the pump case.

Just thought I should share this with you

Regards

Davyboy.

Sorry forgot to mention since the belt and pump replacement I have never had to top up the coolant, I keep mine about 5mm above the lower level in the tank, never on the full mark as touring Switzerland with a caravan two years ago the engine is under a lot of stress with the outside temp being 36-42 degrees C. Touring once upon a time.

If the cap does not seal fully it will permit the water to evaporate when up to temperature, you might see this as water condensing on the bonnet above the tank.

What usually happens is that the presure valve in the lid fails open.

I had the mystery of disappearing coolant too a couple of years back. Eventually discovered it was a broken EGR exhaust cooler. the coolant just dropped into the exhaust and away it disappeared...

Hi everyone,

Having some trouble with our 2008 FL2 HSE

Test centre won’t test as losing coolant fast and smoking - he was to busy to investigate but advised possibly HGF.

I’ve since been told otherwise and to investigate the EGR cooler

Symptoms
Eml appeared but not constantly on.
No heat in cabin via vents
Smokes randomly not every time ran
Quick coolant loss

- no change in drive performance
- no milky oil / cap
- no loss in power

Any advice before next garage spend appreciated

Thanks for reading

Unlikely to be the HG, but the EGR is a possible cause for coolant loss. 2009 Rimini Red SE TD4. My daily driver.

We had a slight coolant loss on our Grey FL2. The engine locked up, and when I took it out of the car found the water pump gasket had a very small leak, hence the slow drop in water level. A new gasket with a thin film of Hylomar Sealant replaced it.

Also a replacement coolant pump drain plug isn't always tight, mine wasn't tight in my Gates kit, which I didn't notice straight away, and I did loose a small amount of coolant. Whilst I was replacing the cylinder head, I noticed a small drip of coolant on the pump drain plug, which was loose when I put an Allen key in it.
Mine hasn't lost a drop of coolant since replacing the head last November. 2009 Rimini Red SE TD4. My daily driver.

Mine had a slow leak from the radiator rotting out. It wasn’t possible to spot the leak as it was on the front side of the rad and coolant loss was minimal. It needed topping up from lower to upper mark every couple of hundred miles.

Eventually it got worse and I had a coolant smell from the engine bay when engine was hot and in standing traffic. I still couldn’t see the leak until I took the front end off and replaced the rad which had rotten out due to leaves and feathers.

Replacement rad came from Poland and was really cheap, turned up and didn’t seem any different to OEM rad. Job wasn’t difficult.

Lol, I spoke too soon.
My TD4 has developed a coolant loss issue, which is rather strange. I can top the tank to the max line, then after a few miles the low coolant message appears on the dash. So I check and it's just below the minimum mark. As I unscrew the pressure cap, there's a release of pressure, and the coolant in the tank rises again to the max mark.

I'm thinking EGR cooler, which is pressurising the coolant under boost, but then sending coolant down the exhaust off boost?

I can't really think of another way this can happen, unless the HG has failed, which will be annoying if it has.

Any suggestions? 2009 Rimini Red SE TD4. My daily driver.
