My car started to leak anti-freeze in the general vicinity of the oil filter. I did no have a chance to really dig in since I'm at work and the car is in the parking lot.

What is back there that contains anti-freeze?

BTW - the temp gauge was normal on the way in except when stopping at a light - then the gauge would go up above 80 then upon normal driving it would go back down to 80.

Thanks

Heater hose flange at the rear of the cylinder head, you need to replace the o-ring. You may want to double check the hose as well, it may have a pin hole.

Good luck
