My e30: its problems and shady past.

I fail to understand what you're pointing out to me.

What's the purpose of the link? To prove my point?

I told you that you were right, didn't I?

water boils at 212 f or 100c degrees at atmospheric pressure under the pressure of the cooilng system it is higher than that

Heat transfer rate is independent of applications...

You are absolutely right...water has better heat transfer rate.

Yeah 100C = about 215f With a proper cooling system I have never had a car get that high in stop and go. At the track drifting with a small radiator yes.

And actually water has better heat transfer than coolant. Glycol lowers the heat transfer properties in water. Guess what! your coolant has plenty of glycol in it. Yes it does raise the boiling point. You where right on that. But its main purpose is to protect against freezing.

And a lot of track cars are only permitted to use water. Primarily because of coolants ability to lubricate. You can imagine the dangers a coolant leak on a high speed raceway would cause. Out of all the time I have spent at the track doing road course and even drifting I have yet to have a car overheat or boil over with just water.

Water boils at 100C. It is awefully hard to keep it from blowing up in stop and go traffic. 50% Antifreeze actually raises the boiling point of the solution and has better heat transfer rate; therefore, much better coolant than water.

yeah, water is much better at cooling than actual coolant. it just has this nasty habit of freezing and expanding.

Oh wait, you just saw the viagra commercial where a guy poured a bottle of water into his overheated '69 Camaro radiator, didn't you?

ok guys an update


flame me when you hear this

so ive been using water since i got it and i drained it and put proper coolant in it

now it's fine.
thanks for replies though guys

I feel really stupid.

It wasn't the water. It was probably air in the system.

Glad to hear you fixed it!

Moral of this story is...bleed before you start replacing :-)

Lol aint that the truth

Yeah, unfortunately these cars will need a pretty penny to get it into tip top shape. The people that are having a blast with their E30s as of right now have gone through many dollars and are now in the downhill of just purely enjoying their cars.

I'm about $2K in and I just bought mine 3 weeks ago...
