Cylinder head torque Specs for 1997 Toyota Previa?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.


The details for Torque specs is as follows :----


Torque sequence: ----------------- 
There are two rows of fasteners and you need to start with the middle 2 fasteners first and then work your way toward the front and back in steps. 
Step 1: torque head bolts #1,2,3,4,5,6,7, & 9 in sequence to 10 Ft/Lbs.
Step 2: torque head bolts #1,2,3,4,5,6,7, & 9 in sequence to 20 Ft/Lbs. 
Step 3: torque head bolts #1,2,3,4,5,6,7, & 9 in sequence to 29 Ft/Lbs. 
Step 4: turn all head bolts in sequence an additional 90 degrees. 
Step 5: turn all head bolts in sequence an additional 90-degrees recheck final torque in sequence. 
Fasteners are supposed to be replaced if they are removed since they are torque-to-yeild fasteners.

7 - 5 - 1 - 3 - 10
front
9 - 4 - 2 - 6 - 8

This basic details will help you.Thanks.

    Hi, I am in the process of head gasket job on 1997 Toyota Previa, wish I wasn't but I've started now.
    Engine is on the floor striped to this point, but I am having difficulty removing the cam chain cover. I can see that the water pump is chain driven from the crank or so it looks but how can this be removed in order to remove the cover? Any tips on this job in general would be most appreciated. Regards, Will. willbastin12@hotmail.co.uk

    On another thought... Do I even need to remove the whole cam cover or can I just release the pre-tensioner and push cam end of the chain to one side and remove the cylinder head?

    Thanks for the links. I'm assuming that the cam sprocket has the be removed from the shaft and left in place as i cant get enough slack on the chain. Is there a link to cam shaft removal instructions? Regards.
