91 Honda Accord

My Accord has been recently over heating and shaking when stopped or idle. And the Maintenance light has just turned RED yesterday while driving. Three Weeks ago the green S light was flashing and my speedometer wasnt working, so I installed a new Speed Sensor and the green S stopped flashing but the maintenance light was still orange up until yesterday while driving it turned RED. I topped my radiator off with antifreeze but everytime I come to a stop my car shakes and starts overheating until I start moving and press on the gas then it goes back to the middle. Then when I got home and turned the car off One Fan cuts on for about 10 mins. I dont know what is wrong and I dont want to buy a new radiator if I dont have to. Please help!

 

Maintenance light?
This one?

 

Yep, thats the one. It went from being just orange to red.

 

The maintenance required indicator doesn't actually communicate with the engine. It just counts miles and changes color at predetermined points. the little hole on the left of that image is how you reset it.
Have you made any changes to the cooling system? How long have you had the car?
shows you pretty much exactly what to do.

 

As "kay" stated, that "reminder" is for oil changes....insert the car key into that slot to the very left of the pic....about where the speedo is pointing.

Bleed the system - several methods - Check for leaks in the system. The coolant went somewhere, need to figure out where.

 

Preciate that fellas. My fluid is leaking out from somewhere, I didn't have that problem when I first bought the car about 6-8 months ago. and it wasn't until I topped it off myself, that's when the car started acting up and I noticed my fluids leaking out under my car two days after I did it. Ill try to find out where its leaking from and Ill let you guys know if the problem still persists.

 

Well considering if you find it shouldn't be to hard to repair this, Good Luck,
