Hi. I just bought a 1994 toyota highlux for my first pickup and i love it so far. When we drove away from the dealership i immediately noticed that the speedometer and odometer dont move at all(seriously they dont wiggle or nothing) and that it overheats. We drove it for thirty minutes and stopped at a resturant to eat and when we stopped we saw that it was spewing coolant out of the overflow. So far i have changed water pump, rad cap, and t-stat. I just bought a new radiator and im gonna put it in tomorrow, i just want to know if the radiator doesn't fix it what else could it be because i know next to nothing about engines im following everyone elses advice and im tired of messing with it i want my truck fixed. In regards to my speed i bought a new speed sensor also gonna change that out tomorrow. If anyone has any suggestions please put them forward ur advice is greatly appreciated.

Btw its a 1994 toyota highlux 2.4 22re 2wd automatic.

 

You need to run a compression check. Make sure it isnt a head gasket blown or other engine problems. When my head gasket went bad, it was overflowing into the coolant bottle.
