The problem began when the service engine soon appears, it was because the water in the radiator was too hot but all the water was there, but boiling. So I got more cold water and the van starts to work properly again for one month more, then the same problem, so I took it to the mechanics and he said next day our van was not start engine, and said was the computer, so I bought want on the junker, and now they said is the computer again because the fans are not working and dont start engine either with the new one. But still doing the same problem, boiling water, fans stock, and the module or computer shows a lot of codes( that was the mecanich said) Im tired of this.

Better quit going there he's nothing but a comedian. When the last time you changed the thermostat and radiator. If the fan is not coming On the engine will get HOT could be the fan motor/relay or temperature sending gauge/switch and coolant temperature sensor.

Do below if the engine continues to overheat:

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following:, Pressure test the Rad. Cap, Clogged radiator, air lock in the cooling system, Fan clutch, Radiator electrical fan, collaspe hoses, water pump.

Engine will not start do below and see what happens

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil, distributor pick-up coil, ignition control module, cam and crank sensors-

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time
