Below are the tightening torques for all two, three and four cylinder engines known from the Mitsubishi K4, K3 and L2 and L3 series. We have these data from official manuals of the respective engines. Where possible, we have added the tightening torque sequence. Translated with www.DeepL.com/Translator (free version)
Mitsubishi tightening torques
It is an important rule that the head bolts must first be oiled, on which the correct NM can then be measured with the torque spanner.
