Hello

I need to change the thermostat on my 3.9 v8 defendeer efi but the bolts are really tight do these normally snap ? any idea how to undo them without breaking them ?

thanks chris

Heat it up with engine running for a while or use butane gas burner and if they do snap it's not the end of the world take the housing of and use a stud extractor

As sible88 above run the engine to warm it up is my favorite plus a splash of plus gas or similar easing oil.

I had to use a blow lamp on one of mine on the 72, I got lucky as it made a fuel line a bit crispy but it didnt catch fire

Wot are your fuel lines doing at the front of the engine?

on an early set up with twin su carbs the line that joins the two carbs goes right by the stat bolts :doh:

Is yours a 3.5 carb then I was under the impression it was a EFI

I have two, well three but ones a parts car.

I have a 1990 3.9 efi
and a 1972 2 door 3.5 with su carbs

The parts car is a 79 but I am gradually swapping the good bits on to my 72
