IF you are talking specifically glider tugging,whilst all that has already been said on here is basically true, there are slight differences to generall flying.
The aircraft will be fitted with a CHT guage ( or at least should be as that is a requirement for tugging approval). It is always advisable to fit an EGT as well.
There should be a prominent placard with CHT limits displayed on the dash,and a section in the POH relating to tugging which should be followed.
Also it is the tug masters duty to make sure that anyone using the plane is familiar with these limitations.
