Coolant level

I've always just used tap water......and my engine hasn't exploded yet.

Not much i can add other than what's already been said ..

Check it when cold and top up if needed ( water is fine due to the shear volume of coolant it won't drop the antifreeze content by much ) it sounds like there was a small airlock which has now cleared ... not unusual shall we say and a bit difficult to predict ..

Some cars are fine after a job like this and others hang onto an airlock for a good few miles .

we tend to tell customers at work .. check it over the next few days until it settles .

Obviously never open the cap with a hot engine .

Thank you. Left the car until it was dead cold (over 24 hours) and the level remained just below minimum.

Topped up with 50/50 coolant/water mix to between the min and max indicated levels. I have re-checked after use and it's stayed at the same level so far but will keep an eye on it.
 
My water pump failed earlier in the year. I had to top up just once after I drove home from the garage. Seems to be fine now and hasn't moved since.
