Does anybody know what size diameter the short approximately 2" hoses are that come off the back of the thermostat on a 2.5 V6?

Are they both the same diameter?

I need to replace the camshaft seals on my GTV6 soon and while the rest of the radiator hoses look good and I have records saying they were replaced only about 20k miles ago, those short hoses have oil on them. I figure I should replace them while I'm in there just to be safe.

Hi there, the 2.5’s, the hoses are the same, on the 3.0 they are stepped. The 2.5 is 24mm hose which is a pain to find. My car came to me with 1”/25.4mm which seems to be working.

Good to know, thanks! I think I have some 1" hose laying around from my last Camaro project. I will check just in case.
