Car issues....need help...?

I have a 2001 jeep wrangler. I recently had the engine replaced and it has been running fine. I got the oil changed at Jiffy Lube and haven't driven it more than 2,500 miles since then, and it is starting to leak a rusty/brown colored liquid from the front end of the car. I noticed that the coolant is almost completely gone, which is weird because jiffy lube oil changes include adding coolant. the oil and transmission fluid levels are fine, and the temperature gauge inside hasn't indicated any overheating. what could be wrong, and how much might your idea cost me?Car issues....need help...?If your coolant level goes below the sensor it will not register properly on the gauge . DO NOT RUN YOUR ENGINE WITH LOW COOLANT. Check the rusty brown liquid to see what it is, put a dab on the tip of your tongue, coolant is sweet to the taste. Car issues....need help...?when the brown liquid comes out of the engine it means that the engine is oxidated on the inside, this happens to engines that had been outside a vehicle and without water sirculation for a while. Also you have a water leak. What that car needs is a leak repair, and then a coolant prssurized fush and add new coolant. it could be a water house either heater or radiator, a leaking radiator or cap, leaking water pump or and engine seal. if the water level goes below the sensor it will not read the temperature of the water and it will fool you. %26quot;Do not put that water on your tongue%26quot; its toxic and full of lead. As a personal note... this jeeps are very problematic as you can see you allready change the engine and now you still have problems.
