Pinto expansion tank

[Theyellowmex]

Is it the norm to run pinto with no expansion tank. Any benefits of running one.if so where are people fitting them in mk2 escort.cheers

[wildo105e]

Never ran one on mine. Don’t think they ever had one in an escort even from Ford.

typically expension tanks are only needed when you dont use a rad with a built in header tank

Many moons ago when we were running NA Cosworth engines in our Rally Car we were often having water problems of various descriptions. We decided the only way was to try running a swirl pot from the head to the top hose. We sealed the radiator filler so the cap couldn't be removed and then fitted a Mk3 Escort expansion tank where the fuse box normally goes on the bulkhead. A small bore pipe then ran from the top of the swirl pot to the top of the header tank to bleed any air out, with a 5/8 hose going from the bottom of the expansion tank to a feed pipe soldered next to the bottom hose on the radiator. This system worked well for us and solved many of the problems we were having.

To answer your question whether a Pinto needs a header tank the answer is no as that engine was always designed to be used with a filler cap on the header tank of the radiator.

The choice of aftermarket alloy radiators seem to be much better nowadays as the only option we would have then was to get one made with a slightly larger core by a Radiator repair specialist, which most of them seem to have all but gone now due to cheap Chineese imports that started flooding the market.

There's no longer the same responce to threads that there once was on this Forum so I decided to make a little bit of effort this morning over a cup of tea. It was also a chance to cast my memory back to some of the trouble we were having at the time with water problems in our engine. Looking back now it doesn't seem half has bad, but at the time it was driving us all mad.

Well i for one find your comments both interesting and infomative.indeed on many occasion you have answered some of my questions along with graham and a few others and been v helpfull and are much appreciated

The in-depth reply is very welcome and unfortunately this is how things get lost in history as people think you don’t want to hear the story!
I personally think it’s great
Do you think the alloy head of the cosworth possibly heats the water over the pinto temps creating air in the system?

I wish i'd never typed a reply now! Glad to see everyone saw it a a 'tongue in cheek' remark - NOT!

Lighten up everyone! - times are dark enough as it is !

Have always run a header tank on my Pinto Mk1 simply because upgraded radiators used to be expensive (comparative to today) so my radiators were sealed units from Transits or Peugeots.

But then I got a nice new radiator for Christmas so its no longer needed.

If anyone is in the market for a cylindrical alloy header tank suitable for a pinto let me know since I've been threatening to drill holes in it and use it as a breather catch tank! It will need a clean and polish mind.

There were many theories has to why the YB engine created air in the cooling system. I had quite a few conversations with various engine builders at the time, each one having a different opion as to what was causing it. One of them even had a transparent top hose made for his dyno so he could see what was going on. It was Roy Millington that said to try a swirl pot and header tank and that seemed to do the trick. I also fitted a Group A Cosworth water pump on his advice which is now fitted to my Pinto engine. Both these items were often fitted on Big Power Cosworth Turbo engines.

I hope this reply isn't too long for you all but there's nothing worse than half a story!
