Got a 2005 Suzuki Swift.

I topped up the engine coolant to almost full mark last tuesday. Now a week later after only 2-3 drives it is about 2 thirds full. So lost a third roughly in a week.

Does this seem right? Not sure if the extremely cold weather impacts the coolant usage? I have only done about 10-15 miles in that time.

Will keep an eye on it and check again next week to see if it has gone down further.

What made you top it up? Was it low anyway?

Did you run heaters after topping up?

Ran heater fair bit yeah but only during my 3 or 4 shortish drives. But they were on for sure.

It was empty before, just a drip in there. I had forgotten to fill it up but know I definitely last fully filled it about 4-5 months ago.
 
ok thanks will have a hunt. I don't smell anything no.

I am using a Halfords pre mixed coolant. Not sure if this would make any diff at all?
 
No repair work in last 6 months no.

It was empty when I last topped it up yes. Good point about it being the expansion tank. I didn't really think of that.

Also, when the coolant is low a warning light should show on the dash right?
 
Yeah it's a chain on the swift, one of the selling points.

Got a guy coming out on thurs to take a look who comes highly recommended. Does mobile repairs. Not sure how he thinks he can check it out on my drive but we will see.

Just an update on this. Went for long drive last weekend. Expected some coolant level drop in the tank but it didn't happen. I filled it up further to half way point few days ago and still no sign of it dropping (although not used car since doing that).

I now get feeling it was just filling up in the main tank and now that is full the expansion tank is maintaining same level. Will monitor though
