General advice:U must track the leak .How much it takes to loose the coolant?.If the coolant shows under the car must identify the tubes clamps that need tighten or replace.If a radiator related problem need clean/solder/replace.If leaky water pump,replace.If no trace of coolant ceck the oil.If is color altered(milky)u have a head gasket ahead (with head revision)or a broken engine block/piston cyclinder.If the oil is ok,ceck the smoke:whity smoke means coolant in the pistons head.Again best guess:head gasket (can leak also in the intake manifold).Very rare coolant shows in some cars in the power stearing oil (!?) track the tubes.Tip:colored coolant (green...)is better visible in leaks.Tip:water coolant may show rusty spots where dissapearing (radiator,expansion deposit,pitched tube).Hope u deal it.Cheers.
Someone else's code may not help you as the light could come on for a number of reasons. Smoke under your hood could be due to a leak or leaks such as oil, coolant, power steering fluid and so on and as the engine gets hot the fluids will burn off on the hot engine or exhaust causing it to smoke. The smell when you turn the heat on could be because your heater core is leaking. This would be accompanied with low coolant levels, overheating and low heat especially at idle also the carpet may be wet. If your vehicle is equipped with a cabin air filter the smell could also come from there as leaves and other debris and sometimes even rodents can get in there. Also if you don't allow you evaporator to dry by shutting off the ac but letting the fan run for a couple of minutes the water on the evaporator can cause mold and mildew to grow giving you a funny smell as well. Hope this helps.
Your heater core has developed a leak (of coolant). The smell is the "sweet" smell of ethylene glycol, a component of engine coolant. The white smoke is steam coming from the heated coolant evaporating. The coolant is dripping into your duct work under the dashboard, and apparently being evaporated out of the ductwork and sent into the passenger compartment, meaning its a small leak. When the leak gets worse, you may get wet carpet on the front passenger side.
There is a drain for the a/c evaporator core is down low on the engine side of the fire wall on the passenger side. Usually it's a very short open ended rubber tube that's a couple of inches long. It gets plugged up with dust and crud. Once the drain is plugged the condensation that occurs on the evaporator coil builds up and overflows out of the HVAC housing and drips on the floor. I just use a gentle puff of shop air to blow the tube clean. If there's a lot of crud in the housing it may plug up again after a while but usually the tube will get washed clean when the a/c runs again. Hardest part is often just finding where the drain is hidden. If you're having trouble finding it and have a friend or neighbor with a similar pickup it's sometimes easiest to watch where the water is dripping out of his and backtrack it up to the drain. Good luck, hope this helps!
you have a coolant leak and its burning off the motor (smoke). your overheating because you have a coolant leak. need to pull the air filter box out of the way and find it.
More than likely it is coming from the intake manifold. You can use a pressure tester that hooks to the radiator and use a flashlight and mirror to get a better look at where it is coming from.
sounds like you need to tighten connections on the housing drain tube with replacement of houses on vehicle replace drain tube
but also it could just be condesation from a/c this is normal
