I had my coolant fluid exchanged at Lube Express on Friday. Come Saturday my coolant light came on. :bang: I know a lot of people have problems with the floater (thanks to the wonderful "Search" button) but I checked the coolant level up front and it's about an inch below the line that reads "Add Coolant". So I'm sure it's safe to assume that they didn't put enough coolant in when they swapped it...:shrug:

Now my next questions is what should I top it off with? Distilled water? More coolant?

Also, is it safe to take off that cap even though it reads "DO NOT OPEN HOT"? Can't I just let the engine completely cool down and then open it? :shrug:

You can add either distilled water or coolant. You should get a coolant tester to determine which would be best. Or you can just add some of one or the other, should not hurt...

You can remove the cap after the engine has cooled down for about a half hour or so. Use a rag to turn the cap just in case, the rag will protect your hand...

Also throw 1-2 bottles of Red Line water wetter in there, it works well :nice:

Should be fine to add distilled water... Ideally, you want to hit a 50/50 or 60/40 mix... If you had a coolant tester you would know which to add towards that mix ratio... If not you should be ok to wing it...

I guess if your anal you could use distilled water but do you think they have a distilled water supply at the dealership? Or do you think its faucet/hose water....just top it off with some tap water..you'll be fine.

yeah I have to top mine up soon, I really want to drain it and refill the whole thing but the car is too low for me to get under, I might try jacking it up from one side, letting in drain and then doing the other side to try and get it all out. I posted a thread a while ago about coolent flush but alot of people said the experienced leaks after they had it done.

Since we're on the subject of coolant, I'll ask a question here instead of making a whole new thread: Draining the radiator drains less than half of what the engine sees. I heard there is a coolant drain plug on the block? Can anyone explain?

there are drain plugs on either side of the block. they are hex plugs and one is next to teh dipstick, the other is in a similar place on the other side of the block. draining the radiator does not get the crap that is stuck in the bottom of the block out. i would only really top off with water wetter if you are going to use pure water. when i build up my motor i will only run water and water wetter. im sure the track will appreciate that if god forbid i send a connecting rod through my motor in a braking zone.

After I had my coolant exchanged out last year the coolant light would come on in the mornings when it was really cool outside for about a minute then shut off after I've drove it around. If yours is going on and off you may have an air bubble in the system they didn't get out and that's causing the light go on and off. Should take it back and ask them to purge the system just to double check and make sure all the air is out of the system.
