Location Replacement And Function Of All 28 Coolant Hoses On the Porsche 996 997 Engine M96 M97 

⭐️⭐️⭐️⭐️⭐️ 5 star Porsche content👍

That’s nuts!! I was wanting to replace all the coolant hoses on my 997 when I do my water pump, LTT, and add a 3rd radiator, but that’s just crazy.

If an NA 996 has this many coolant lines, imagine how many lines a new 992 has with its turbo engine

thanks! very useful - im doing the same replacement on my 996 and it’s painful to find and source them. plus i have a third radiator at the front!!

Prudent decision in replacing all the old contaminated hoses.

I wish I knew you were going to replace the radiators - I have 2 OEM that are gathering dust in my garage after changing to CSF.

Great job with this! Very helpful! I realize this is a year old, but would you mind posting the parts list? The Porsche printed diagrams are a challenge, and the dealer network... well.... not incredibly helpful

I've dealt with several vehicles that had oil, ATF, or diesel fuel in the cooling system that didn't suffer any hose or radiator issues.

Hi Nathan, very informative as always. Is resurfacing the cylinder head mandatory or would you advise resurfacing them even if they're not leaking? Thanks, Quentin

😱😱😱

Hi Nathan I'm having the same problem, my porsche dealer is having an issue when ever I'm asking for thr hose parts they themselves dunno where and what is. Do u remember the part number for the hoses?

Just a point to make about the title. The 997 coolant pipes are significantly different to the 996.

Now can you do that on a 991.1.

They said basically you brought the car for 15000 with all the parts that you replaced that car should cost at least $26,500.00

12 up front? I thought it was 3 on each side = 6 up front…?

That's what happens when you put an engine in the rear. So much unnecessary parts to make it work. You also lose trunk space, and no the frunk is not the same. Porsche should just put their engines in the front. I can't stand the new models where you can't even see the engine and the rear bumper has to be removed for every little maintenance.

All these hoses are failure points. Rubber has a shelf life.
