I have a question and hope someone can help. Last night my daughter drove up to grab food. She said that her car was smoking under the hood. Went to look at it. The plastic cap for her coolant had popped off, fluids all over inside of hood. Coolant was empty. Refilled coolant with 50/50 ready to use mix. She was driving to work today. Temp gauge spiked, light came on and Jeep started shaking. She pulled over to the side of the highway. When I got there, I was able to drive it to an empty parking lot. Temp gauge was at 3/4 towards hot. No shaking. Cap still on. Any ideas?

Why was the cap off in the first place? Has she been checking or adding coolant? How far was it driven hot. You can't trust the temp gauge in this situation because the temp sensor reads coolant, not air so if the system runs severely low, the gauge can't read and it only takes a manner of minutes to do severe internal damage to the engine. At this point you need to tow it back and refill the system and then pressure test the system for leaks. Remember when you initially fill it with coolant, it's not really full. It's full of air pockets that need to be "burped" out. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

It was not hot then. Normal temps. But she called me because it was smoking. She didn't even know how to pop the hood so she has not checked or added anything. When she was on the highway is when it spiked to hot and the light came on. She pulled over immediately. I got there and drove it less than a mile to the parking lot. It was not hot then. At the 3/4 mark.

It was not hot then. You don't really know that. Like I said, when the coolant is low the gauge will read wrong. A minute is plenty of time to warp an aluminum block/head. You need to do what I advised to find out if it's OK. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
