Here's what I got: 1989 FJ62. Here's the situation: I know it has been covered out there, but I am at a loss with this situation. Water pump was leaking through weep hole so I replaced it (non-Toyota) along with EVERY single coolant/heater hose and belts from Toyota. Filled her up with a 50/50 mixture and burped her until I could no longer. She has ran just below the second line in between the 2/3 and 3/3 sections. Replaced the t-stat thinking that maybe the wax inside broke down. Same thing. I am thinking it's the water pump, but I have only ran into one water pump not working correctly off the shelf. The coolant that came out was still nice and not discolored at all. I can hear the fan clutch engaging and disengaging. I have no idea what to do next other than replace the water pump. Any ideas would be a great help.
