Thread: "Normal" Coolant Consumption??

I have the same problem.but I changed my upper radiator hose and every time I check my container its lower every time!!!

i've discovered that air bubbles cause ALOT of people issues with sr20's seems like.....mine had a good sised bubble and would try and overheat in the middle of the night(i get off work at 1am)after like 3 blocks of driving....FINALLY got my bubble out and not a single issue since....even drove it for a week with nothing but water and still didn't overheat....i had to park my car on a hill with the nose higher than the rear to coax the bubble to come out but not it's good to go

Well at the end it was just a minor crack on the top hose, change it, and 0% coolant consumption... the strange part is that it never leaked, i'm guessing that due to heat it would just evaporate...

The coolant system is a closed system so what evaporates will condense again. But coolant evaporates hardly. Ever cleaned some spilled coolant with a cloth? The cloth won't dry.

I owned a Toyota that required about a quart every 40k miles and in the end I replaced my leaking radiator. (it blew after a trackday and 2 hours of autobahn back home)

Then it never used coolant again.

It can leak without leaving stains on the floor. Keep an eye on the coolant however, small leakage through the head gasket can take a while before you notice but you should smell coolant in the interrior when driving and from the exhaust. With older cars head gasket might just get worn out but if it really starts to leak there you could end up with a damaged engine.

So it is still a serious issue to diagnose properly before racing it.
