Changing the rad

Thanks for the responses folks.
I just thought I'd check as I've read other threads where the cowls have been left off, the thinking being that this creates better airflow whilst the car is moving but as always with this type of thing there is divided opinion.
Mad Mark, you can buy 'through radiator mounting kits' which allow you to bolt the fans directly onto the surface of the rad, Pacet do such a kit I believe.
cheers

Ooohh I see :-) I never knew about those. I just thought I'd check as I've read other threads where the cowls have been left off, the thinking being that this creates better airflow whilst the car is moving but as always with this type of thing there is divided opinion.

Going on your first theory which does make sense but these cars don't have an issue with being hot while in motion it's when stationary they get hot.
What is worth doing before putting the radiator back in and is often overlooked is to seal around the top, bottom and sides of the radiator and cowl. So that all the air the fan pulls through the rad comes from through the front of the car rather than pulling hot air back through from round the sides.
Foam strips for this purpose can be bought from the TVR parts store. Or B and Q sell something similar.

That's a good tip, thank you for that.Going on your first theory which does make sense but these cars don't have an issue with being hot while in motion it's when stationary they get hot.

Hope you don't mind the thread-jack
BUT
I want to find and replace my bottom hose.
Are there any photos/hints that you can share as to how to do this.
(ideally I'd like to do it with the rad in situ
)

No problem at all with the thread-jack. I see no reason why you can't change the bottom hose with the rad in situ. The biggest problem you'll have is if the last person to work on it positioned the jubilee clips in such a way that you need to dislocate your wrist to get at the 7mm nuts. Be prepared for the deluge of coolant when you remove the hose, 15 litres is an awful lot BUT

Paul. What is it you need to see? Perhaps if I try something a little less subtle…..

Are you referring to the smaller length bottom hose attached to the radiator or the longer one that goes to the thermostat?
It's the bottom, small (?) one, I thnk.
I replaced the pipes about a thousand years ago for those neoprene ones from ACT. All ,that is, apart from the Radiator Drain Hose. I know that if I don't do it soon, it'll burst on me, somewhere in a traffic jam, halfway up a mountain, in Italy, on a Saturday morning, with the Pubs closed.
Just couldn't find it when I had a good look underneath
( I presume that it's on the offside)

It is offside but you can't see it from underneath very easily. The rubber section is hidden behind the large chassis box section and the body. It's the bottom, small (?) one, I thnk.

Look on my facebook page in the "oops....." Album. there's pics in there showing its position.

I haven't got any pics I'm afraid and as the plumbing is still out of the car I can't take one either. The hose is really easy to find though. Offside, looking down into the engine bay, right at the bottom of the rad with the hose heading towards the centre of the car at roughly a 45degree angle.
