Radiator Choice

[Guest danny_samb]

Hi all iv got a 2b with a sierra dohc engine fitted. The rad iv currently got is weeping so need a new one, it's at an angle but I now want an alloy rad and one that can stand up straight, what's people's views on rad choice, it doesn't need a rad cap as got header tank

Polo rad seems to be popular choice which is way I am going thanks to Alfa gta

Polo rads are cheap and easy to fit but arent alloy.

 

I and a few others use Honda civic alloy rads cheap and cheerful

But they are fitted with a rad cap.maybe you can blank it off

Hi went on eBay and bought a alloy one of there to fit a escort / Sierra I think pretty much all the same my bottom outlet pipe is different to the ally one I got and have got move the water temp switch from the rad where it was originally on, to the water pipe work. I will be buying silicone pipes for the engine so wasn't worried about the bits I would need to change I think I paied £80 for mine by biding on it just measure your old rad and make sure the new one is the same size hope this helps.

Why do you want to stand it upright when at an angle increases the "effective area" presented to the airstream and makes it more efficient?

Want to stand it upright so I can get the air filter down into the nose cone instead of on top of the radiator, so it will give me a bit more space in the engine bay, surely if it was best to have it angled then all factory made cars would be like it?

Angled makes if more awkward to fit.

Its easier for manufacturers to specify a slightly larger rad instead.

I fitted an all alloy mk2 rs 2000rad upright it kept my warmish 2.1 pinto cool .off ebay 125 delivered mick

[Guest danny_samb]

I was looking at an alloy rad out of a mini pretty similar size to civic, outlets in the positions I need, but it has a rad cap, can I run with the rad cap but not use it or just get it chopped off and a plate welded over

I also run the DOHC in my 2b.

I had lots of overheating problems to start with but after clearing endless parts from in the nose cone, fitting an air scoop under the front angled cross member and going back to the old fashioned overflow system with an 16 psi rad cap, l now never overheat.

That is with the cortina type radiator fitted vertically.

You can use a plain blanking cap on the rad, (but if it has an overflow spout you need to blank it off) and use the pressure cap on the header tank.

[Guest danny_samb]

Would that rad I have put a link to be suitable or too small?

[Guest 2b cruising]

Classic mini ones are short on volume.

I think that's why in the day of the mini, most kits used Triumph or Ford rads.

Moggy rad tended to be wider.
