That's an expanding band clamp (It goes by many names).

Basically to release it you press down on both the rectangular protrusions, this releases the internal metal bands from the groove in the pipe spigot on the radiator.

To refit it you just push it on and it clips into the groove, there is a rubber O-Ring in the fitting that seals the connection.

Unfortunately in your attempt to get it off you appear to have damaged the clamp. To be honest if I were you I would purchase a new lower radiator hose (it comes with a new fitting already attached), as when they get old the sealing O-Ring has a tendency not to seal well again once disturbed and can leak.

As it's going to be a track car, you don't want upset the track marshals by dumping coolant all over the track.  ;)

And yes, you can continue to use the green coolant green, just make sure you give the radiator AND the block a good flush.

So figured I would spend some time on finishing up a few things. Trial fit of 60s le mans 24 hour race car livery ;D 8).

Well if you're ever coming up behind someone on the track they can't say they didn't see you coming . . . . . the guys on the ISS could see you coming!  ;)

Thanks Bazz. That's a great idea on the new hose so will get a new one. If anyone knows of any motorsport sets than I may as well replace as many as possible while I am doing it.

Yep in a 24h race I should be able to still be seen in the middle of the night ;D. ISS is too easy, hopefully the Mars Rover takes a few snaps ;D

Nifty solution for keeping the power window switches. Used two of the metal brackets that were already there for a screw and screw with nut.

Highly recommend the sparco tow straps as the D Bracket holes fit the bolts perfectly. I pointed the flat side of the d bracket to the sky so the strap doesn't drag along the ground. You will have to drill a new hole in the bumper so wouldn't recommend towing straps for a street registered car.

Turns out the optional? 17x7 wheels are from Speedline in Italy. This is after one coat of plastidip gloss white. A whole can was used for the two wheel. I would suggest 1 full can per wheel as I only bought 3 as recommended by the ebay store. So another coat and than a clear coat and should look like a 156 touring car ;D 8) ::)

One can of clear coat can easily do 2 wheels. It won't win any concours d'elegance but for around $50 for plastidip and clear coat its not a bad result from a distance ;D

The speedlines are the sturdiest of 156/147/GT stock wheels. I have a set, but one is slightly buckled nonetheless. Ti wheels are the lightest of 17", 2 kg lighter than speedlines.

Though you'd eventually want a set of 16" to fit within TS cup regs.

It's been 17 pages, so I forgot if you've got tires already or not. So I can recommend Hankook RS4 or Sailun Atrezza. Both work well on track and are cheap. Hankook will last a bit more but is more expensive too.

I'm curious as to how much car mass has been lost as a result of the fairly comprehensive shedding of material.
Did you weigh the car prior to hacking in to it? 
The club has corner weight scales if you want weigh the car.  Just need to find a very flat surface.

I bought the control tyre for the ts cup but obviously can't race it due to the size of the wheel. May as well get used it on sprints.

General question: I found out that there are two categories of racing in the Twin Spark Cup? 1 for cars with a roll cage and 1 for street cars without a roll cage? If so, I couldn't tell by reading the regulations. I bought slotted discs as well early on but apparently the street car category can't use slotted discs?

Warsch you are right about the rear pads being pretty useless. These were down to the metal and I couldn't tell on the drive home when I bought the car ;D.

Regardless car is on the home stretch as will be ready for Phillip Island in a couple weeks as it's going to Maureci Motors to get the bucket seat and harness installed, timing belt and water pump and wheel alignment. Just ran out of time to do the timing belt etc myself.

I am happy to weigh the car Colin. If you are at Phillip Island at the AROCA sprint than we could set them up? I took out the foam bumper bits behind the bumper, most of the dash is gone etc

My 156 is give or take in the same condition and it weights 1130 kg with full tank but there's still some stuff to be removed. We've got a competitor here with full on race 156 and it weighs 1050 kg with a roll cage

Federals are a good choice, though for some strange reason they never appealed to me. 225 is a tad wide for 7" wide rim, but they'll be fine. The paint on the wheels looks quite good.

Good luck with your first outing, please make some pictures and videos and share

Should be fun!

Found out my rims are slightly buckled as well but its not a safety concern. They cost around $200 a side to unbuckle them so will just put that money to a set of NEW 16x7s as I am guessing almost all 20 year old wheels that have lived in the real world are slightly buckled.

Wanted to research the touring cars weight and there is a book on it already. Amazon have some 2nd hand copies at a good price.
