Well a few weeks ago my car, 1999 Formula, overheated on me. coolant was coming out of the overflow tank. I changed the radiator cap and thermostat. Worked well for about a week. then it started to slowly loose coolant till one day coolant was everywhere in my engine bay. I changed the water pump.
It ran like a champ for about a week.

Now here i am. The fans are kicking on, new stat, cap and pump. But coolant is still coming out of the overflow tank. On cold days its fine but warm days like the 80's it messes up on me fairly quick.

Like it was warm this morning i drove to work and my light came on. I filled up the radiator and went to the job. Almost to the job and the light comes on. I work for a few hours then fill up the radiator again. The temp dropped about 15º outside and on the drive home no problems. I get home and theres a bit too much coolant in the overflow tank but no light is on. I check it out and everything is looking good so i drive it around for about 30 minutes. I drive slow, as if i'm in traffic, then i go wot through 4th gear. Car was just fine. It's bipolar i tell you.
Anyone have any ideas? I'm thinking go ahead and change the hoses and if nothing then put a new radiator in
