Yak 3. Not loosing coolant fast enough?

[CrazyGman]

I was playing fighting the Yak 3 in combat yesterday, and I noticed it seemed to not loose coolant at the new changed rate that we see in the BF-109s, Spitfires, and P-51s. I haven't had a chance to test this yet with the other Yaks yet, but I wonder if it was just missed.

Also I was wondering does the Yak 3 not have Shell ejection chutes like the other yaks? Haven't been able to confirm this from pictures of Yak 3's in museums.
