Need to check all 4 corners of the intake manifold with your fingers and see if they get wet. Also check the heater hose's were they go into the intake and see if the fittings are leaking coolant. It is real common for the intakes to leak on that engine.
anti-freeze (coolant) leek
yes any car can
Leak in heater core
My 97 Tahoe was leaking coolant and I couldn't find anything on the driveway or anywhere else. I took it to my mechanic and it was a rear manifold gasket leak, cost me about 500 dollars.
You do not recharge coolant, you replace it. If you are referring to refrigerant in the A/C unit, then first you need to have the leak repaired. It would not need recharging unless it is leaking. It is illegal to add refrigerant to a system that is leaking without repairing the leak. This is a job for a professional with the proper tools and knowledge. This is not a DIY repair. The cost depends on where the leak is.
Replace the master cylinder.
pressurize the system. that'll make the leak leak faster and you should be able to find it easier.
Yes it can.
you can't. you need to fix what is causing the fuel vapor leak.
It could be from many areas such as the water pump, the radiator, radiator hoses, heater hoses, heater core, freeze plugs, intake manifold gaskets, etc. Take a good flash light and try to locate the source of the coolant leak. If you have no luck that way take it to your local garage and they can pressure test the coolant system to force the leak.
You can remove your Chevy Tahoe fuel line by turning the fuel line swivel nuts to the left. Removing and replacing the fuel line is the best way to repair a fuel line leak.
