I have 105K on my 04 and want to replace the antifreeze and all coolant hoses. So other than the two radiator hoses which are easy, can anyone tell me how many I should be looking for, and where they might be located? Heater hoses too.

hose to the turbo. you will see the themostat in the middle of the metal pipe to the upper hose. the turbo coolant hose is known to leak with age. although i have almost 200,000 and no leaks

So if I take it into the local dealer and tell them to replace every line or hose that has anti-freeze in it, what will the parts replaced list look like. Three hoses total?? I can't believe that's all. Hell if it is only three, even I can do that. There must be more than 3.

There are some smaller hoses on top of the water pump...they are about the size of vacuum hoses.

Went to the dealer yesterday to ask how much to do all the hoses, and SM said it would be a waste of money. He said with the new anti-freeze he can't remember when he has seen a blown hose or line. So I plan to just drain the anti-freeze and replace it with new.

The only one i have had a problem with is the small one on top that goes to the turbo.

I had the one right behind the front pulley go. I had a heck of a time changing it. It's only about 4"s long and about 3/8 size. This one went out about a week after changing the one on the turbo. I changed the one down in the valley as well.

I wouldn't replace the hoses either I have 155k and they are all like new. The one behind the fan clutch pully is a beeotch it would cost a couple hundred dollars to change that one alone

I agree with him, its not like the old days, coolant contains no silica. I don't remember the last time a saw a rotted hose on a newer machine at the dealer....

When you change your coolant make sure you get a waterpump when your at the partstore getting your antifreeze because 9 times out of 10 the pump will start leaking after you put the new coolant in. Then you can put new bypass hoses on the pump while your doing it.

I must be the 10th. Replaced my coolant right at five years and am still on the original water pump. That was about 35,000 miles ago.
