I definitely have a coolant leak somewhere, but can't find it. I replaced the water pump 2 yrs. Ago. I spoke with my the same mechanic last week about adding coolant to the overflow jug on a weekly basis & he suggested replacing the radiator cap first. He said run it a few days and if you're still losing fluid, just bring it in.
But I don't have the money to pay someone right now.
A few weeks ago I paid a guy to look for my leak & he replaced the top radiator hose. He added Stop Lean & a few days later he added Barrs' stop leak. He also spilled anti-freeze on the belt when replacing the hose I heard a whining noise daily. Then a few days later when I cranked it up I heard a loud grinding noise. We raised the hood to see where the noise was coming from & I learned that the jeep has two fans. So the smaller fan was coming loose somehow & hitting the fanbelt & grinding away the fan itself. The guy fixing all of this says he never touched that fan so he doesn't know what's wrong with it. So now he's done working on my car. FIRED.
My son decided that the way to hold this fan in place was to fill the screw or bolt hole? We don't have any idea how this jeep works. So my son put a screwdriver in the hole with the silicon, let it sit overnight and took the screwdriver out & it seems to hold the fan in place. He may have ruined it, and it may not even be working.
Two days ago the check engine light comes on for the very first time. When I turned the jeep off and restarted the engine, the light went off.

Today my son drove 6 miles home from work & he tells me that the light is on constantly. So we checked all fluids & topped off the oil, power steering fluid & added antifreeze directly into the radiator & some in the overflow jug.
I sent my son to get groceries and run the jeep for a while to see if the light would go off & when he came home he said that my battery indicator gauge is showing that the charge isn't holding now & the check engine light is still on. It's turned into a mountain of a problem. Can you guys help?

Read the codes this way, and post the results, the fan sounds like it may need to be replaced, especially if the blades are damaged, overheating will occur with this condition, Pressure test the cooling system, Autozone rents the tools, and refunds ALL your money when you return the tool=Free rentals!
Using Malfunction Indicator Light (MIL) 1. Ensure battery is fully charged. Turn ignition on and note operation of MIL. The MIL is located in message center above instrument panel. When ignition is first turned on, MIL should come on and remain on for 3 seconds to verify bulb and circuit operation and then go off. 2. Attempt to start engine. Turn ignition off. Without starting engine, turn ignition on, off, on, off and on within 5 seconds. Record 2-digit Diagnostic Trouble Codes (DTCs) as displayed by flashing MIL. 3. For example, DTC 24 will be displayed by 2 flashes, short pause and then 4 flashes. A short pause will exist between first and second digits on DTC. If more than one DTC is stored, after first DTC is displayed, there will be a longer pause and then another stored DTC will be displayed. 4. Once all DTCs are recorded, proceed to retrieving DTCs using scan tool to ensure all DTCs are obtained. See USING SCAN TOOL. NOTE: If MIL does not come on for 3 seconds and then go off, bulb circuit may be defective or problem area may exist on wire between between Powertrain Control Module (PCM) and instrument cluster.
