Question about 1996 Toyota RAV4
Rav 4 1998
How do I remove radiator, has air and two fans located behind and connected to radiator.
Insufficient room to lift out radiator
Normally, the fan will not spin at the same RPM as the engine. This is
the purpose of the fan clutch. On the fan clutch sits a little thermal
spring that engages the clutch to spin the fan at the same rpm as the
motor when the motor gets hotter than normal.
Being able to hold onto the fan while the motor is running, is normal (not recommended, but normal).
You can test the clutch by heating it and then trying to spin the fan while the motor is off. If it is still easy to spin, you could have a bad fan clutch, or you didn't heat it enough. It is kind of a crappy way to test.
You not having cooling issues leads me to guess that your clutch is alright. But I don't know what type of climate you live it, nor do I know in what condition your clutch is.
They can actually be difficult to replace. Easy theory, but actually doing the job may be harder than you think. They are threaded onto the water pump pulley (just one big threaded stud). To remove you need to either be really crafty, or you need a wrench designed to hold the pulley in place while you loosen the clutch and fan assembly. No, the pulley drive belt is not enough to keep the pulley from turning (it will either slip or you will turn the crank of the motor).
Usually they are on there pretty tight! When I replaced my water pump on my truck, I could not remove the fand and clutch from the water pump while in the truck (I had to remove my radiator shroud and remove it all in one piece) then I had to weld the old water pump impeller to the casting to keep it from spinning then broke it loose with a 2ft breaker bar! Seriously.
Once you get the old one off, remove the fan and bolt it to your new clutch unit. Then thread it on the water pump.

You should check the 30 amp "RDI" fuse and the 7.5 ECU-IG fuse. Both fuses are critical to the operation of the fan system. The RDI fuse sends power to the fan #1 relay. The A/C amplifier turns on power to the fan #1 relay, this is why your fan works on A/C.
Now, with no cooling fan under "normal conditions" (A/C off), you need to have a good fan #2 relay, and a good water temp switch. This switch is on the engine, near the thermostat housing (I think); with a single plug, with a white with a blue trace wire going to it. Remove this wire from the sender, and jump it to ground (anywhere on the metal of the engine) with the key on (engine OFF). If the fan starts, you need a new water temp sending unit. If not, then consider a new fan #2 relay. This system is pretty simple.

You need to walk the pulley off.You will need three long bolts that match the thread in the balancer.Undo the centre bolt about half way and bolt the puller to the pulley.the centr bolt is used so the puller has something to push on in the centre Once you have wound the puller up and pulls the balancer until its stopped by the centre bolt.Undo the puller so you can unwind the centre bolt some more and repeat until the balancer falls off.Every thing must be evenly bolted,puller must be mounted squarely or you will have real trouble removing it.Unless the seal can be removed and replaced from the outside of the timing cover you should not need to replace anything else.Did you check the oil pressure switch as the amount of oil your talking about doesnt usualy leak that badly from a balancer seal

SOURCE: 1998 RAV4 TYRE PRESSURE??
the correct tire pressure is located on the side of your tires and usually the passenger tires are 34 P.S.I. sometimes a litttle more depending on your tires. if you have 4x4 you should have no problem driving on the beach i would just stay away from the water,

sorry never done one so i havent a clue,in the good old days the tach connected to the coil wire but now with all this fancy electrics ,Well what happens is they call it vehicle security so they dont have to release the diagrams and this is done to stop people like myself from by passing the immobilisers when we service a vehicle.Because no doubt as you are aware on new cars that if you drop the oil the immobiliser cuts in.Change the battery and the same thing happens.So what happens to keep the dealers in work ,yes you have guessed it no wiring diagrams ,multilayered circuit boards and wires all the same colour to stop people like me from soldering the two outside legs together of a big switching transistor together to make the vehicle general mechanic friendly.Also encrypted software is used to stop the fault codes from being read ,they throw up the wrong code ?? try asking dealer to install then post where he connected too .,best of british with it
