Antifreeze Condensation on Deck lid

[kk2002s]

Here's what I did to isolate the condensation issue.
Take off the Coolant cover plate.
Place sandwich baggies over the purge valve and the Fill cap
Then place clear plastic wrap over the top of the tank.
You will then be able to see which one is creating condensation.
For me it was purge valve. I replaced the 2 'O' rings and cleaned up some sloppy sealant in the purge value assemble and WALA - no more condensation issues

I did the above and got the engine coolant up to 180 degrees. Will let the car sit in the garage a while and see what turns up.....

I checked for antifreeze condensation in the small plastic bags over the coolant cap and relief valve after the car sat for several hours in the garage. I only see a small amount of sweating in the bag that's on the coolant cap. I am thinking the earlier antifreeze condensation may have come from the coolant cap not being tightened completely....Hope so anyway! I will continue to monitor for Antifreeze condensation on the deck lid.

After a drive today I found more antifreeze condensation on the deck lid. Now I need to find a decent price on a coolant cap.

Just last week i had a coolant cap fail, and thought my car was down for the count. I thought the head cracked, the water pump went out, or the tank cracked. $7.99 for a coolant cap, and all is well. If its leaking, dont push your luck, replace it before your engine overheats and dumps 3 gallons of coolant on the ground.
