Can anyone please tell me what the torque settings for the cylider head bolts should be please?

Question

Renault Clio 1.2 1992

Answer 1

torque setting for cars are according to the size of the bolts being torqued, 15mm can take more torque than a 12 mm . and not knowing the bolt size it would be a hazzard to break a head bolt. 13mm bolt 130 ft lbs start in middle and work out in 3 sets 50 lbs ,, 90 ft lbs 130 ft lbs....alway starting in the middle and alternating from one side to the other side of middle 15 mm = 150ft lbs

Answer 2

Not only is the torque for a bolt determined by thread size, but also by the grade of the bolt. The grade of a bolt can be read by looking at the head, or hex end of the bolt. If it has more than 5 hash marks, then you can go by the recommended torques given by another here. If it has less than five, they shouldn't be used for head bolts.

Also, the torque sequence should be from center out to side to opposite bottom side, like so.

.7..........3..........1..........5..........9


10.........6..........2..........4..........8

Answer 3

Remember they have to be done in a certain order and in incremental stages. Usually the final in a head is 65 ft lbs. Would start at 20, then 30 then 45 then 65

Answer 4

You are going to need to get a service manual for this car.

For that vehicle I doubt the information is on the net.
