Busy day today having striped and replaced the timing belt, tensioner, idler, water pump, thermostat, top and bottom radiator hoses and a full flush of the system.
Apart from the belt most of the parts looked original so for peace of mind I have done the above and kept the old water pump, thermostat, top and bottom rad hoses, tensioner and idler as spares given they would get me out of trouble if needed. All parts are OEM (Toyota) for peace of mind.
Here goes.....
First undo the 4 12mm bolts holding the from brush guard and slide it out to one side. Next place a bucket able to take a good 11l+ under the right side if the radiator looking from the front and undo the drain at the bottom right corner.
Next unbolt the power steering reservoir, it's 3 12mm bolts and pull to the left out of the way.
Unbolt the timing belt covers 3 10mm bolts along the bottom edge and the three clips at the top and remove.
This is what lies underneath
The idler and tensioner below
Here is the top dead centre mark you need to use to line the pulley with later.
Next crack off the 12mm retaining bolt that holds the alternator in place and undo the tensioning bolt to then swing the alternator in so you release tension on the belts so they can be removed. If you can't move the alternator you might need to crack off the alternator pivot bolt it's a 14mm bolt at the base accessed from underneath.
Here is the 12mm bolt mentioned above just above the belts
And the alternator pivot bolt pictured from below
Next I removed the top and bottom radiator hoses along with radiator cowling which is held on by 2 12mm bolt at the top.
At the same time as removing the cowling I unbolted the fan an viscous coupling and pulled it all out together. The coupling and fan are help on by 4 12mm nuts and it bolts to the water pump.
Above is the water pump which you can see and the 4 studs the fan bolts too.
Next with a 32mm socket rotate the crank clockwise to line up the TDC mark on the case and pulley.
With the mark lined up grab the belt with one hand and with a 19mm socket you can "shock" the pulley bolt loose. By this I mean wack it with you hand fast to loosen it up but don't let the pulley move.
With the bolt loose but still in place remove the tensioner and idler you need a 10mm socket and 8mm Allen key.
The belt can then be removed
The old belt still in good condition
Now remove the pulley bolt and the pulley but careful not to loos the key for the pulley
What it looks like all removed
Now you can remove the cover held on by 12mm bolts.
You can now access the water pump and it's 8 12mm bolts that holt it on
2 of the 8 bolts are 14mm actually and hold the alternator tensioner in place
Pump removed but don't forget the gasket
Next I removed the ac compressor by undoing the 4 12mm bolts and pulled it to one side do I could access the alternator and I removed that too so I could get to the thermostat. You could gain access from the bottom but I like working from the top.
Undo the 3 12mm bolts to remove the down pipe housing the thermostat
On removing the pipe you can lever out the thermostat
I now removed the bucket and grabbed the hose to flush the engine out until the water runs clear
Next I cleaned up the pipe and alu plate as it had some gasket maker on it.
Dived into the parts bin and took out what I need to put it all back together and the torque wrench
New pump going in
Some gasket sealer as required on the plate
Next bolt up the plate and install the key, pulley and bolt along with timing belt new tensioner and idler
Above you can see the new tensioner and pin that holds the piston in place until bolted in place and then you pull the pin out
After that it was time to put all the other bits back but I left out the thermostat to run a flush through the system but the light faded on me so that's for tomorrow after which I will install the new thermostat
Will post more on the flush tomorrow for those interested in the results
