It's an easy - but a little fiddly - DIY job, maybe an hour to take out and an hour to put in. It's easier if you remove th bonnet, only 2 bolts each side in the 'mouth' of the grille.
Disconnect the Fan connections, disconnect the hoses top and bottom (the bottom one is the 'drain plug'. It's a lot lot easier to just cut the bottom hose in half with a stanley knife, and replace with a new one. Then remove the 2 mounting bolts and lift and 'jiggle' it out. Refitting is a bit of a pain as the bottom hose is a ba$$td to connect. I had mine recored at a local company for £130 ish. When you ask your local Radiator refurb company to recore it, ask them if thy have done TVR's before. Although the Rad s based on (I think) on something exotic like a a Land/Range Rover the internals are differsnt. A decent Rad company will know.
PS the bottom hose is really hard to get hold of - I hd to go and buy a 2m length of Silicone Hose even though I only needed about 8" - but your in luck as I have some left, if you want it, drop me a mail with your address and I'll post it off.

I found the hardest part was getting the nearside bracket on the radiator past the air con hose. Agree with the difficulty in getting a replacement bit of hose for the lower connection, I too had to buy a metre length!
Found it easier to connect the lower hose to the rad before dropping it down fully, then disconnecting a hose on the 'swan neck' pipe which allowed that to move enough to maneouvre it in. Then tighten the hose clamps after the rad is bolted in.

Just a thought that may help, I have just had a polished alloy rad fitted to my 4.5, changing the rad was straight forward, the people you need to speak to who make these rads are Radtech on 01543 502525. The rad fits perfectly with no mods, they will also help you out with hoses if required, I know the alloy rad is more expensive at £450 ish, but they do look and perform better, they also do alloy header tanks and full silicone hose kits for the 4.5, not sure about the 4.2 I think they may be the same.
