Theres a slight antifreeze smell i was just wandering if it a heater core problem and i have to replace it or try to get it flushed if it could be clogged. Mount the unit using its bolts.

If this is what happened you should be able to look under the dash above and to the right of the gas pedal and you will see two vaccuum accuators one of them you should be able to wiggle around the linkage if it is broke.
