Anyone have the coolant level change in the reservoir after the change? I filled the coolant to the max line and it's now below the halfway mark. I'm thinking it's the system just working out the final air bubbles, but not entirely sure.

Any input on the subject is always appreciated. Thanks.

 

Yea it probably used some, if your not getting any weird idle or over heating issue its prolly fine. Of course that is assuming you no leaks or anything.

 

Yeah if you have no leaks its normal for the coolant level to go up and down when it cools off. Dont rely so much on the min and max lines. I have an aftermarket coolant tank and there are no min and max lines. Just check it every now and then and if it gets too low then top it off.

 

i'd be shocked if he level stayed the same.

 

In the billman coolant change diy, he says to overfill resevoir a half inch to allow for additional air to work its way out of the system (which will then be replaced with fluid from overflow after radiator cools.)

So some amount of such settling is normal. If you didn't do a really good job of bleeding the air during your change, even more settling would occur.

The danger here is if you didn't do a good enough job bleeding and there is still some air, car is a potential catastrophic overheat ticking time bomb. It can drive perfectly for days or weeks, then one day overheat itself to engine destruction. These cars in particular are susceptible to this. Take this seriously.

One way to tell if you have a problem is if heat doesn't blow so hot you can barely keep your hand on the vent. If your heat isn't blowing this hot, stop driving car immediately.

If the heater core has air, this is what will happen, heat not as hot as it should be. Keep bleeding.
