How hard can coolant tank replacement be?

[78F350]

After reading all the horror stories, I was disappointed with how easy mine was when I did it.
These two two threads were very helpful:
DIY Coolant Tank Replacement in Under 2 Hours
Another coolant tank replacement DIY

Here's notes from when I did mine:

Notes:

• Disconnect the oil fill tube in the engine compartment first. Less stress on the hard plastic portion.
• One of the rubber hoses has a quick disconnect in the engine compartment. Easy to use that and get the clamp after it's all out.
• Use flexible hose clamp pliers.

The oily grit is probably left over from the blown and partially disconnected AOS when I bought the car. That's a hard to see/clean spot. The bottom 3 hoses came off pretty easily from here.


The last hose could be pulled into the trunk far enough that it was easy to remove after everything else was freed.


Here it all is, with the tools I used.


It was not bad at all. For the installation, I put all the hoses on the manifold, then pushed them through to the engine side. Easier to reach the hose to hose connections. I tried using a screw-type hose clamp. Bad idea. It is so much easier with the original clamps and hose clamp pliers. I wore 7 Mil nitrile gloves and didn't lose any skin or blood. Topped it off with Peak Long Life that I had picked up on the way home from the track. No need for the pink stuff in this car.

Lastly, many people have tried to save a little money buying a cheaper coolant tank. Many of those people have posted their regrets.

I got a really cheap expansion tank. $49.95 or so shipped. From Amazon. So far it's worked out really well. Guess I've been lucky. NLA, btw. But there is this:

Mine wasn't so easy the first time, the Porsche factory elves seem to get a perverse delight installing those spring clamps pointing the wrong direction so they're impossible to compress. I put it back together, with a new oil fill tube and a new dipstick tube. Reused all the spring clamps except the two that go to the metal coolant tubes (replace those rubber hoses,) those were brand new worm drive clamps, the best I could find. Makes getting it all loose again more of a piece o' cake. In case my cheap coolant tank needs replacing in 4 or 5 years.

I think I will give it go!
I may get a new oil filler tube as mine looks oily.
Did anyone replace the temp sensor?
I also thought about replacing water pump at same time but is in only 3 1/2 yrs/23,000 miles old (replaced with IMS) so if looks ok it can wait until next time.
Of course I will get the real Porsche tank!

Thanks for all the advice.

Decent price. Yes.

Would you take a moment to share the $49.95 link?

Thank you.

I would if I could, I looked it up in my Amazon orders and it's no longer available. Closest thing on Amazon is this:

https://www.amazon.com/Coolant-Reservoir-Porsche-Boxster-99610614708/dp/B078NG7CRQ/ref=sr_1_1?s=automotive&ie=UTF8&qid=1523400007&sr=1-1&keywords=Engine+Coolant+Recovery+Tank%2FReservoir+ For+Porsche+Boxster+99610614708

I wouldn't hesitate to get one, but install it so it's easier to remove, particularly the clamps on the hoses that connect to the car's coolant system metal tubes. I use worm drive clamps on those two hoses.

You can get a cable type hose clamp compressor on Ebay--works okay for $11, but I ended up resoldering the ferule on the cable. And a cheap set of coolant how picks from Harbor Freight, too. Replace those hoses, btw. My replacements were from auto parts shop bulk stock and went on tight enough that I had to use Sil-Glide to get them to slip on.

The quality of mine is as good as the factory oem.

That's arguable. If there's one thing I've learned from these forums is that, unless you're doing some modding, if it's connected to the engine, it's OEM only.

Can we make this a sticky!

Another Question!
Has anyone experience of using a Coolant Air purge / Refill tool? - such as 'Schwaben 003466SCH01 Coolant Refill/Air Purge Tool'

Seems like a good idea and easier than than all the engine revving method.

Look into UView. There is a basic one for around $80 but it needs an air compressor. I used a 6 Lb pancake without issue

[rexcramer]

I just used the Uview 550000 Airlift on a 97. I paid $138 plus tax via a Brazilian Prime river. It is amazingly simple to use. Youtube videos convinced me. That and my indie wanted over $400 to flush and fill. Times two cars to do, the savings is significant for me. I say go for it. If you have the skills to R&R the tank, you have the skills to use it. The times savings alone is worth it.

Another question.
Did you guys re-use the hose clamps or use new ones or new screw type clamps.
Thanks.

Ahh - just looked at the post below which answers my question! I will try and re-use.

I reuse them, except where the hoses go on the metal tubes of the car's coolant system. Those are worm drive. When you put on the spring clamps plan the location of the jaws for if you ever need to take them off. The clamps that Porsche uses are really good clamps, just knuckle busters to get off (which is why replacing the tank is such a pain in the arse.)

[rexcramer]

I had 2 screw and 3 spring. I changed them all out for new screws.
