Torque settings for 1.4 cvh escort 1998 replace head gasket. also do headbolts need replacing with new ones ie are they stretch bolts

try this head torgue link.. that wont highlight

the ZD30 is listed half way down the list
and picture of tension sequence

HEAD BOLT TIGHTENING SEQUENCE.
• STEP ONE: 102Nm
• STEP TWO: Loosen All Bolts.
• STEP THREE: 44Nm
• STEP FOUR: +90*
• STEP FIVE: +90*
• IMPORTANT: ALL BOLT THREADS, BOLTHEADS AND WASHERS MUST BE LIGHTLY OILED.
• USING AN OLD HEADBOLT WITH GROOVE CUT DOWN THREAD, CLEAN THE BLOCK HEADBOLT THREADS.




why are these torque setting and sequence
numbers no longer on the VRS head gasket packaging

Since you didn't say which engine you have, I've pulled torque specs for 3 different engines. Also, since I can't include a diagram showing the relative locations of the numbered head-bolt locations, it would be a good idea for you to purchase a vehicle specific repair guide that will show this info.

Take particular note about the TTY (Torque to Yield) bolts used on 2 of the 3 engines shown. It is said that new head bolts MUST BE USED when head is replaced or re-installed to obtain the proper torque.

B2500 4 Cylinder

Torque sequence: --------- ' 10 6 2 4 8 ' front ' ' ' 7 3 1 5 9 ' -----------Step 1: torque in sequence to 51 Ft/Lbs Step 2: torque again in sequence to 51 Ft/Lbs Step 3: final tighten all bolts an additional 90 to 100 degrees recheck final torque in sequence *** CAUTION ***engine uses Torque To Yield head bolts (TTY) that permanently stretch during the initial installation. New head bolts must be used when cylinder head is replaced or re-installed to obtain proper torque.

B3000 3.0 6 Cylinder

Torque sequence ---------- ' 6 4 2 8 ' ' ' ' 5 1 3 7 ' ---------- Step 1: torque to 59 Ft/Lbs Step 2: loosen in sequence (1) full turn Step 3: torque to 41 Ft/Lbs Step 4: torque to 73 Ft/Lbs

B4000 4.0 6 Cylinder

Torque sequence --------- ' 5 1 3 7 ' ' ' ' 6 4 2 8 ' --------- Step 1: torque cylinder head bolts in sequence to 26 Ft/Lbs Step 2: torque cylinder head bolts to 56 Ft/Lbs Step 3: turn cylinder head bolts in sequence an additional 90-degrees recheck final torque in sequence *** CAUTION ***engine uses Torque To Yield head bolts (TTY) that permanently stretch during the initial installation. New head bolts must be used when cylinder head is replaced or re-installed to obtain proper torque.

Good luck with this job!

heres the torque specs and the way to tighten the head bolts for your 1998 toyota sienna, hope this helps,
12 point bolts step 1- 40 ft lbs
step 2- additional 90 degrees
recessed bolt 13 ftlbs

hi yes here are the torque settings

stage 1 is 25nm
stage 2 is 45nm
stage 3 is turn 105 degrees

try leaving about 10 mins between each torque so it can settle also you have to tighten them in sequence and make sure you use new head bolts as these are the stretch type and if you are using the old ones there could be a chance of one snapping, just a little advice..hope this helped

What happens is the head gaskets shrink causing the headbolts to loose torgue, and the headbolts are of one time use, whenever you do a headgasket job you will need to replace all the headbolts with new ones. and when ever you remove a cylinder head on any engine you should always chase the bolt holes with the proper tap, then blow out the holes with compressed air, this will help to insure a more accurate torque setting on the new headbolts...

Always use new head bolts.
1)tighten to 40ft/lbs
2)back off 1/2 turn
3)tighten back to 40ft/lbs
4)tighten an additional 90 degrees
5)tighten an additional 90 degrees.

Hope this helps, from autozone site. Curt

Cylinder head bolt torque sequence

Note :
Torque sequence:
---------
front | 3 1 6 |
of | |
vehicle | 5 2 4 |
---------
Step 1: Lightly oil cylinder bolt threads & washers
Step 2: Torque to 22 Ft/Lbs
Step 3: Torque to 51 Ft/Lbs
Step 4: Loosen all bolts 180 degrees
Step 5: Loosen all bolts 180 degrees
Step 6: Torque bolts 1 & 2 to 25 Ft/Lbs
Step 7: Torque bolts 3, 4, 5, 6 to 11 Ft/Lbs
Step 8: Turn all bolts an additional 80 to 90 degrees
Step 9: Turn all bolts an additional 80 to 90 degrees
*** CAUTION ***
engine uses Torque To Yield head bolts (TTY) that
permanently stretch during the initial installation.
New head bolts must be used when cylinder head is
replaced or re-installed to obtain proper Torque.

There should be 10 headbolts. This vehicle uses torque to yield headbolts and should be replaced with the new gasket. Bolts 1-8 get torqued to 40 ft lbs initially, bolts 9 and 10 get torqued to 30 ft lbs initially, Then all bolts get turned an additional 90 degrees. I would strongly suggest borrowing a torque angle gauge for doing this or you might be doing the same repair next week.

Stage 1 = 15Nm
Stage 2 = 40Nm
Stage 3 = Plus 90 degrees or quarter of a turn. Good tip is to mark all the bolts after initial torque setting with tip-ex , i.e. all to the front of the car. When you finish they should all point towards the timing belt.
This is also a good way to make sure you don't miss one or tighten one twice if you are distracted since it is not a torque setting. New bolts should be used by the way as they are stretch bolts. Timing of cams - remove cam cover and you will see a slot on the end of the cams. Opposite end from belt. You need to slip a piece of 5mm flat bar or a long 5mm allen key into then so that the bar rests on the face of the head. Engine should be a tdc.
