loosing anit freeze

are they very exspensive

it is leaking behind the motor is it a hose or heater core hose

perhaps you could tighten the "breeze clamp" these can be undone and installed without removing the existing piping~

I had that problem with my Grand Prix. It ended up being the heater hose bypass elbows. They are a couple of shitty plastic fittings that become very brittle and crack. I replaced them with Aluminum ones so that wouldn't happen again. Make sure you get them replaced before they catastrophically fail like they did for me. You have to remove the alternator to access them. Part # 47065HP. If you buy it on rockauto.com, you can use my 5% discount code: 1861354412629810.
