coolant level going down get fog inside of van after the thermostat opens . Must be either the front heater coil or the plumbing to the passanger compartment heater coil. am getting fog from both front and back none of my books show a diagram to the plumbing system for the heater system under the dash. Also cannot find data plate for the engine what number on the vin designates the engine size and what number is for what cc size?coolant level going down get fog inside of van after the thermostat opens .

take to a mechanic and have the coolant system pressure tested , that will force the coolant from where the leak is and will be able to see what is leaking , i suspect a split/worn hose
if you see no visable leaks, or puddles on ground under vehicle to pinpoint leak, but keep having to add coolant I would suspect intake gasket leak. coolant burning through exhaust system, when really bad excessive white smoke from exhaust will be noticable
The tank is loosing coolant because there is a leak somewhere in the cooling system. I would have the system pressure tested to verify there is a leak. Sense there is a odor in the car and the coolant is low ..I would suspect the heater core is leaking. A pressure test will help locate the leak in the system.
Well depending on what engine is in this vehicle, it could possibly be the water pump that is leaking or possibly a "freeze out" plug on the block. I would say it is more than likely the water pump. If you have no noticeable leaks from any of the hoses or radiator, i would definitely suspect the water pump or possibly the thermostat housing may have cracked and started to leak. My suggestion would be to look at all your hoses carefullly and then check the housings where the hoses connect to the engine block, if no signs of coolant are present, check around the water pump for noticeable coolant leaks. Hope this helps in your search for that coolant leak.
Thanks for choosing FixYa and welcome to the site. The thermostat is the most common issue with overheating. This is just a recap of other issues that can cause overheating. Be sure to check your coolant level and make sure you are not leaking coolant in the engine compartment. You may need to buy a new coolant cap. Make sure your fans are working properly. If they are not, check the fuse for the fans. Make sure your radiator is not leaking and working properly. Make sure there ae no damaged hoses or missing clamps. If all this checks out, it may be your water pump. If you have any questions, just let me know. Thanks for using FixYa.
on the s10 pick ups, they commonly had a 2.2 liter engine. that engine is suspect to external head gasket failures. it is very obvious once seen. if you have the 4.3 liter..they are suspect to the intake manifold gaskets leaking...hope this helps
Any hose is suspect as is the raditor. park over a ditch or other way so you can get under the car and it still level. inspect from the bottom having someone squeezing the hoses till you find wher the leak is.. It'll need to be full of coolant all the way to be sure where the leak is.
check condition of radiator,radiator & heater hoses,look for spots wet w/ coolant.look more or less straight up above where coolant puddles on ground.engine block is equipped w/'freeze plugs' that sometimes corrode & leak.washing suspected area of leak with an engine degreaser product may aid in locating source of leak.
