My Toyota Estima Lucida model 1994 is overheating what may be the problem and possible solutions to fix the problem.

You may have a cracked head if so have i tested it only take 10 minutes at any garage. Also have the thermostate cheaked.
Also the water pump
I hope this helps you wityh your problems

First check the coolant level, then check to see if the fan is working.
if low on coolant then fill it up and check for leak.
if fan don't come on then check fuse and wiring
if you have a fan driven by a blet then do not have to check the fuse.
