split header/expansion tank - water leak
« on: 29 August 2004, 16:11 »
I've had a water leak for a couple of weeks now and it's really annoying because I had to keep putting water in every 3 days. (usually in a rush cos I'm late for work), but yesterday I fitted a replacement tank in the hope that would cure it.

it turned out where the top and bottom peices join had split. I've been told the 20v has a high pressure water system so the increased pressure on a 17 year old tank took it's toll. anyway, a quick trip to the scrapper and I had a mk3 item ready to be fitted. I could of gone for a mk2 one, but a) there were none in the yard at the time and b) the mk3 ones look more moden.

I had to make up a couple of L shaped brackets to mount the tank on and then solder on the new plug to connect to the coolent sensor in the tank, but other than that it was a simple replacement jobby. I also had to swap the larger of the 2 hoses that connect to the tank due to the repositioned plug on the bottom, but that wasn't hard. I need to get some smaller bolts to hold the brackets too.

it now looks much better under the bonnet and so far no more leaks. I'm going to leave it a couple of days just to be sure before I put some anti-freeze in. Shame my washer bottle is so grimy now? ::)

Looks good, you could lose the water bottle, our mk1 one is now in the spare tyre well, along with the battery etc...

that's the next plan Clair. Then thread the loom through the chassis leg out of sight. Hopefully it'll look good then. With regards to putting the battery in the well how did you secure it to the floor? welding a bracket? I'm assuming I can use the original water tube for the washers?

I just cleaned the new tank up with water and a tooth brush. looks new now ;D

cheers

Should have had the washer bottle out of the MK3 whilst you were there :)
Oh and the washer jet tubing as its a sexy black colour rather than orrilble brown sun damaged MK2 stuff ;)
