I'm going to change the antifreeze out in my' 90 L-98 coupe. Any special tips I should know? And when replacing, how much is recommended for periodic freezing weather, and why only a 50/50 mix

Asked by kevinmac1955 Dec 26, 2014 at 01:52 PM about the 1990 Chevrolet Corvette Coupe RWD

Question type: Maintenance & Repair

Recommended? Is a certain amount
of water needed in system? I'm
aware of using the GM type for the
aluminum parts. Can't find any help,
any input out there? Thanks

Hello again, i was looking around the radiator to find the petcock and noticed the front of radiator was packed full of debris, not leaves and paper, almost looked like mud and hair, maybe part of a roadkill. Have to take shroud, intake filter housing, etc, apart, to get in there to clean off. Hoping between that and fresh flush and new antifreeze, my overheating issue will scratched off the list. I'm hopefull. Anybody know where the petcock is?? Can't find it anywhere.
