Yesterday I was in climb from Pennsylvania and I could smell hot rubber and the CHT was high but not in the red. Everything else was normal for an 85 degree day. I leveled off right away and it cooled down and the smell went away. I slowly climbed to 4000 where the air was cool and continued 1.5 hours home everything looked good.
I inspected it before putting it away and found anti freeze spread spit out on the belly and firewall. The resivoir was empty but the filler was almost full.
I can find no leaks . I wiped it down , refilled and fired it up to operating temp with no leaks . I will let it sit for awhile and check some more.
I figure I will start replacing hoses and clamps. Is there a thormostat anywhere?

I appreciate any advice.
