Triumph Sports Cars

For a radiator in my TR6 I ordered a Griffin like many people, but I was wondering if you guys are using an overflow tank or a surge tank. I figure that the radiator will be high enough to avoid a pressurized surge tank but an overflow tank seems like a good idea.

I read all of the Triumph photo gallery right-ups but no one mentioned anything.

By the way, today I finished installing the Tilton hydraulic release bearing so now I have an installed crate 302 and T5. Yay! Once the radiator is set up I can start her up.


Thanks,

George

Congrats! George, On progress with your build.

I did run an overflow tank(does not have a cap),with my Griffin radiator, for my ls1. It also has a drian down valve on the bottom of the overflow tank.

I just started it up, so haven't had it on the road yet, to see how it works out.

Please do a video(Of your start up) for us if you can, share with us your progress.

George,
I originally installed an aluminum tubular type overflow tank. Then, in the belief it wasn't big enough, I added a custom built one in parallel to give me more volume (painted black unit in photo).
Hope this helps. You definetely want an overflow tank of some kind so your rad will draw back the coolant.

I fabricated a tank from aluminum and tucked it away behind the right front wheel well. Go to the photo gallery on this site and look up Dale Knapke, TR6 photos. The first two photos after the write-up show the tank in the upper right hand corner of the photo.

Thanks for the help. I'll keep you guys posted on my progress but I'm too embarrassed to post a start-up video. The Engine Factory did all the work - they even sent me a video of it running.

My only work was reading out my visa number. By the end I was indeed sweating, but I think the reason is elsewhere.

George,
Please do keep us posted on your progress,and by all means do save a video to post on this incredible website of how it was done, for learning and inspiration to others! No matter what the cost or how it was built, the satisfaction of knowing your dream will live for many to enjoy!

Calvin,
Great build!!
Have been following for quite some time, Looking forward to the reveal and stories to come!!!


Ken,
Very Clean Ride!!

Yeah, you will need an overflow of some sort. Get one that the line from the radiator goes into the tank below the level of fluid, that way when you engine cools down your system can draw back any fluid that was expanded out of the radiator. I think any sort of track will require an overflow so you don't spill coolant on the pavement, you don't want coolant on your tires, makes things very slippery. There are a couple pictures of my setup on my engine page (http://www.ls1gt6.com/enginetrans.html). I am very happy with the functionality of mine, but only somewhat pleased with how it looks, I am not the best aluminum welder in the world, it looks better in person though. The overflow hose on the radiator goes into the bottom of the tank in my design, that way it can pull all the fluid out of th resevoir if needed, most have a hose that goes through the top and down into the coolant, I worry about the hose coming off becoming suctioned to the bottom or other variables that the bottom input design should eliminate. Either way parts stores online have many variations from pretty cheap to pretty expensive.

Jon,

That's quite the build. Now I don't feel so overwhelmed by my minor problems.

Here is a photo of what I'm using for an overflow tank. It is in the same place as Ken's car.

George,
Yeah, the build got a little more involved than i anticipated. It's amazing how much one little decision can alter so many variables, and before you know it, you need new suspension all around, etc. Keep up the progress, it's nice when you are coming to the end.
