    Coolant coming from evap drain after upper coolant hose replacement

    So I've done some research on a heater core replacement and am fully aware of what it entails, but just wanted to get an opinion first before I disassemble the whole dash. My upper coolant hose had a leak, so I replaced it and "burped" the air out of the radiator and everything seemed fine...

    Radiator leak?

    hello all, is this a radiator leak? I assume it is. How long do I have before radiator is considered shot? Should I replace now, or within a month or two? I have a very small bead of coolant under radiator, it's dropped maybe a drop or two a day max. As one can see, bottom of radiator is wet...

Go to almost any car forum out there, and you'll find a slew of members who like to push the idea that making your engine run cooler is a good thing. Often times they'll...

    Cooling System

    Losing my hair from scratching my head! Although Stinger does not have a jeep engine anymore the general principles remain the same. There is a smell of anti freeze when I turn the heater on. Although my A/C is not yet reconnected to the system when I switch to any of the A/C functions the...
