Coolant tank replacement

[timbo]

Just replaced the coolant tank on my 2000 Boxster, found one tip to pass on, I found that by removeing the two pins securing the clamm shell and swinging out of the way I could get much better access and you dont get the greasy mark on your left shoulder from the locating pin. I also found that Mole Grips worked well on the clamps and that its best to leave the pipes on at the tank and remove them from inside the engine compartment.

While doing this I discovered that the oil filler tube had worn right through in several places, would this have any effect on the running of the engine as this would mean there could be no vacuum?

I can tell you from experience that a hole in the oil filler tube will affect engine performance big-time. They get brittle with age and break quite easily. The part is a bit of a pain to replace but is doable with some patience (and a magnetic pick-up tool for the inevitable times that you drop the bolt!  :censored: )

Hi newart1, luckily I spotted it while the coolant tank was out, no bolts on mine just two spring clamps.

Okay, you're referring to the upper half of the tube. Check the other part (hard plastic, bolted on to the crankcase near the alternator) for cracks while you're in there. Any leaks in this will cause you grief.

Ok, see what you mean, yeh upper half rubbed on the body, will check lower half when next in there, dare I say running great at the moment with 90k miles.
