I smell antfreeze when turning a corner in my 1996 Chev s-10 w/ 4.3. No visible leaks and no over heating. Help?

I have found vac. leaks by taking a can of starter fluid and lightly spraying the hoses you suspect are bad, do one at a time and see if the engine revs. up, if it does you have a vac. leak close to where you sprayed the starting fluid.......Hope that helps...

I have a 1999 Chevrolet Lumina with the 3.8L engine. In 2009 I also smelled fuel when I drove my car. My leak was located at the fuel rail output connector. Chev house said I had to replace the entire fuel line all the way back to the tank. Say what? I easily fixed the problem by installing a NAPA #7304922 3/8" Nylon Fuel Line Retainer (repair kit - $25).

Check the coolant level if low air in the system will cause little or no heat out the vents. If coolant good I'd recommend replacing thermostat. If low would some sort of coolant leak, possible waterpump leak, or hoses if visible on the ground after filling. If no visible leaks could be head gasket leaks.

You may need a thermostat and a coolant flush but one thing you can try first is disconnecting the heater hoses and run a garden hose with low pressure through the heater core both directions.These are commonly known to get plugged heater cores. If flushing the heater core out brings your heat back definitely get a coolant flush. Make sure to dispose of any antfreeze properly.

water pipe split or broke

its caused by your aircon the hose may leaking under your dash board

Likely you are in the beginning stage of a heater core leak. at this point, you may be able to temporarily solve the problem by using a good system sealer (I'm partial to the kind that comes as a silver powder) Since we don't actually know the condition of the core, temporary may mean a week or several years, but replacement is expensive and time consuming so I'd definitely give it a try.

have you been using the defroster or defogger because these also run the compressor causing condensation....


since you said there's also condensation near your dash vents, it leads be to believe that the fluid will not be brake fluid or hydraulic fluid.

those cars have had numerous problems with leaking fuel injectors,the problem is that its hard to find due to the heat of the engine drying the fuel up before it can make a visible drip or stain.Please address this quickly due to the danger of fires.

take it to mechanic QUICK
