Disappearing Act

Hi all

Yes an other Low Coolant problem topic!

A few days ago I posted a topic about overfilling my Coolant Tank when I noticed the coolant to be somewhat on the low side.

No big deal so I did a top up, but ended up overfilling. I was worried as to this causing some problems but have been assured it's no big deal.

Ok so now today after been parked in the garage for 8 days I decided to go for a spin, but before I did or even started the engine I checked the

coolant level! and it seem pretty empty almost dry (see pictures)

I topped up with just some still bottle drinking water (had no spare anti-freeze at my home) And went for a spin then checked again coolant level

after the engine had cooled down and to my surprise there was no drop in the coolant level at all?

So my questions are:

1. What are the main coolant loss problem area's

2. If parked for long time can the coolant evaporate

3. What would you guys check.

P.s. 9 months ago (or 5000 miles ago) I replaced for new these parts.

1. What are the main coolant loss problem area's

Coolant tank, hoses/clamps, water pump, radiators, head gaskets, cylinder heads.

2. If parked for long time can the coolant evaporate

Absolutely not...........

3. What would you guys check.

System pressure test; if loosing pressure, add UV dye and try to spot leak(s). If no external leaks, look for intermix, run cylinder leak down.

Have you looked at your oil to see if there are any signs of coolant/contamination?

Thanks guys,

I've checked for intermix contamination, and the oil filler tube/cap was as clean as a whistle as was the coolant tank,

NO signs of a mayo like substance!

(I'm familiar with this as I've had an engine replacement about 2 years or 12,000 miles ago)

I have the car booked into my friends garage, but he cant check it until the 12th of June.

I think I'll run a System pressure test and Run a cylinder leak down test.

Will keep you's posted.

In the mean time I'm off to Malta for a 5 day vacation.

So I'm going to try and not worry about it
