So i just bought a high miles Seqoia. 233000 on the clock. Vehicle is in pretty good shape interior is perfect minis door speakers. Did a fluids check. Changed oil, did two rounds of trans fluid drain and refill. Check front and rear diffs, checked transfer case all good and full will change soon. Changed plugs as the electrode was almost gone and the gap was massive. So did a vin history report through Toyota website and not many maint records minus brakes and inspection. Nothing to show timing belt was ever done. Pulled one of the covers off and looked at the belt and it appears to be in good shape. Water pump looked newer as it had no corrosion or build up on it. Is it safe to take the chance and assume that it was done at 90000 and then again at 180000 and continue to drive it until 270000 and change it then?
