My Liana was around 65k when sold although my uncle liana (maintained by me) is near 280k without any major engine replacement in order to keep gaslet fault less
1)use good coolant
2)never remove t.valve
3)keep close eye on temperature needle in bumper to bumper traffic
4)specially for Liana use 1.1 bar radiator cap there were several case posted on Liana FAn club where ppl blown there gasket by using 0.9 bar radiator cap
