duracool is in!
the air blows cold - sort of.
I got the duracool the other day and pulled 20 inches of vacuum on the system. added 3 cans of duracool and test drove it. vent temps are between 45 - 60 degrees which isn't all that bad considering the outside temp is 100+. it's better than nothing for sure. but I think I should be getting lower vent temps than that. my jeep cools to around 37 degrees. perhaps - despite my best efforts - I have air leaks under the dash. the heater controls and the glove box are very cold, and almost no air flows from the center vent. does that sound like air leaks? I thought I'd fixed them all with duct tape and made sure the hoses were all on tight. what a PITA. there must be an easier way. If I buy a new hose kit will they be more flexible? will they stay on the connections better? what have you all done to fix this? jones

Kind of sounds like your duct work is plugged somewhere. Have you taken the box apart on the engine side of the firewall to see if it is plugged up? Maybe a mouse nest somewhere in the ducting. As to the temp of the air that you do get, maybe the water shut-off valve isn't working properly. Just a thought. WES www.ClassicHeartbeat.com

thanks,
ya I've had the box and hoses off & out. didn't find any obstructions. just loose fittings and rotten hoses. the heater valve is new but I'll go feel the hoses and check if it's working. jones

Sounds Cool. Imagine what it would be like if it was pulled down to 30 inches for a half an hour.
 What is this stuff compatable with, R12 or 134A? Denny |

The repro hose are way more flexible than the original. The new ones are basically plastic sheeting with a spiral wire inside. The originals are wound and tend to come unwound with age. Before you tear it all apart again, I'd get new hoses. No sense going to all that trouble twice. If there isn't much air coming out of the center vent but your glove box is cold, then you have a leak somewhere. Is there cold air coming out of the floor heater register? If so, mayber your flapper door in the diverter box is not working.
