Project 33: from the 101 Projects for your Porsche Boxster book

I got the dreaded coolant tank leak in my 1998 Porsche Boxster 986. Went ahead and changed it myself. This has been the most difficult DIY to date, but it’s still doable!

I made as detailed a video as I could. There are some really hard to reach hose clamps that make this job difficult, and therefore they are also really hard to video. But I think this video will really help anyone that’s willing to tackle this project themselves!

It was also recommended that I go ahead and change the thermostat and water pump at the same time, so that’s my next job, and of course I’ll be making a how-to for that as well!

Love your vids…TTG… but get a microphone so that we can better hear you. You know… a clip on… bluetooth… wireless… anything. Also, assume that anyone tackling anything under the "hood" already knows how to access it… maybe refer them to another vid. That alone would save 15 minutes. Cheers!

Good Video. Some suggestions since I used your video to replace my coolant tank.

1. When you remove the old tank just cut the two hoses that attach to the aluminum supply and return lines, with a utility knife A lot easier than messing with the clamps and they only cost around $8 each to replace.
2. When attaching the new tank through the firewall, lube the insides of the two short hoses with some coolant. They will slide on the aluminum tubes nicely.
3. The bottom hose is just an overflow that can be attached after all of the others. It gives you more room in the engine bay. One less hose to get in the way. You can put this hose on by just feeling around the bulkhead since there is not one of those dreaded hose clips.
4. The special tool is a MUST to do this job.
5. It's a pain but very doable by the amatuer mechanic.

Thanks again.
