try turning on the fan switch in the car
If a coolant leak were caused by brake work, I'd never have that person work on my brakes - ever. Just the brakes, I would think it highly unlikely that it would result in a coolant leak. If they were replacing the master cylinder, then I could see a possibility of someone inadvertently causing a coolant leak, but that would still even be a stretch.
coolant temp sensor, wiring, relay, bad fan motor
Coolant Temperature Sensor
you might have to replace your water pump, coolant, or coolant fan switch wich is located behind the power steering fluid. If none of those work you might have a vacuum leak
Yes. The coolant carries the engine heat to the heater core. Without coolant the heater core does not get warm.
There are hoses, gaskets amd water pump which cause leaking. Check it out where the coolant is comming from.. The speed sensor is probablu bad.
Any 3.8L V6 from a 1995-2002 Camaro/Firebird would work
Test the coolant freeze point to be sure the coolant is not freezing up when it is cold outside.
will a 3.8 engine from a2002 Camaro interchange with a1999 camaro
You may smell coolant when the ac is running but a leak in the heater core won't cause the ac not to work.
We need more information. Never work? Come on and not blink? Do the 4way flashers work?
Yes.
