1999 Jeep Grand Cherokee Lerado, low coolant alarm

My low coolant alarm goes off when I start my car after it has been sitting for several hours. My coolant levels are fine and my jeep heats good. I'm thinking I just need to change my sensor but I am not quite sure.

This same thing happened to mine. It only happened in really cold weather though. I added a few inches more of coolant into the overflow. It fixed the problem. I also discovered if that is not the problem, the sensor in the overflow can go out and a replacement is about 20 bucks.

Remember that as the car warms up the coolant level will rise....check the level in the bottle when the car is cold as this is where the sensor is located

My 1999 jeep grand cherokee is slow to start after sitting for a hour or so


Most likely the fuel pump is going bad most common problem is running it low on fuel causing it to heat up and cause cavitation in the pump ruining the pump check valve. so the pump has to be replaced and so does the fuel pump sock.

Engine code 95 jeep grand cherokee lerado


12 is a battery disconnect within the last 50 start cycles and 55 means the end of the diagnostic cycle.  Basically the computer found nothing wrong. The 12 code may seem incorrect if you haven't disconnected the battery recently, but from my experience the 12 code shows up almost all the time regardless.
