    My Z passed the Mot again without any issues but has developed a small pin hole leak in the core. I took it down to my local radiator company whom said the core is NLA and it’s not repairable.

    This leaves me with an issue. Does the earlier rad ie brass type which is available in the US fit a facelift ie. plastic end tanks ???

    hi mate,the rad is as you say unobtainable in the uk, and is not repairable i spoke to many people on the matter,i think pre facelift and facelift rads are the same,i can confirm the US rad will fit as i have one on my car,but it only has one sensor hole in the bottom of the rad the uk rad having 2,also the top hose is on a different angle so i used a US hose

    Thanks for the reply. How did you get round the sensor issue? Did you just delete one? I presume one would have been for the air con if fitted?

    You haven't said what year your Z is but you need to be careful as there are 2 types. The earlier type for a 240Z has an outlet pipe that is angled upwards and has a different hose that attaches to the outlet pipe on the block whereas the later one is a straight outlet pipe. Both will fit on the car but will need different top & bottom hoses. you won't get any original spec radiators like this in the UK unless someone has a used one.

    You can get aftermarket alloy radiators in the UK that will fit and they tend to be better on the cooling. The downside is that they are not OEM and don't look anything like the originals. Some of the cheaper ones off Ebay have fitment issues and some have poor welding. I managed to pick up a reasonably good quality rad off ebay for £120 which was a 4 row. The quality alternative is a Mishimoto at about £250 ish - again you can get this in the UK.

    Thanks for the info about a breaker. I’ll keep that for anything else I need but I’ve ordered a new one from the US. I’ll keep you posted regarding fitment.

    I’ve gone for the same slant type one fitted but it’s made of brass.

    Got the other hose also so fingers crossed won’t have any issues fitting this!

    Next on the list is tracking down my speedo issue. I’ve got a few spare speed senders to try
