Bigj66 Posted July 24, 2020 Share Posted July 24, 2020 I’ve seen a diagram online that suggests the Rangy P38 4.0 Thor radiator part number PCC106850 has a core depth of 40mm. Any P38 owners can confirm that as it sounds a bit thin for a V8? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted July 24, 2020 Share Posted July 24, 2020 They are a very efficient modern radiator, so no need for any greater depth. You simply can't compare to say, a series radiator. Quote Link to comment Share on other sites More sharing options...

Reason I ask is that I’ve been speaking to a well known ally radiator specialist who are adamant than nothing under a 50mm core will cool a V8 sufficiently. But then I saw that diagram which clearly states 40mm 🤷♂️ A 40mm core would be ideal for my project so if this is correct then it gives me more ideas to work on 👍 I’d also be interested in the height and width of the header tanks if anyone just happens to be walking past a P38 Thor rad with a tape measure in their hand....😉 If anybody can also tell me the thread size of the gearbox oil cooler hose fittings that would also be appreciated.

Bowie69 Posted July 24, 2020 Share Posted July 24, 2020 Well, personally I think that is nonsense, if it is a specialist aftermarket rad manufacturer of course they are going to say that, or you won't buy one of theirs. Also, aftermarket stuff tends to be a coarser core than modern stuff, making them less efficient, if that is what they are using, then perhaps ask if they can use something more akin to a modern oem radiator. Otherwise, I would be trying to fit the largest off the shelf item possible. 1 Quote Link to comment Share on other sites More sharing options...
smallfry Posted July 25, 2020 Share Posted July 25, 2020 I would always try to use an OE unit if you can cobble it in. From what I have seen, aftermarket/custom rads have hefty fins and tubes more suited to an intercooler IMO. I have got a Lexus LS400 one here, which produces far more HP than a Rover, and its only about 20mm thick. Quote Link to comment Share on other sites More sharing options...

I was wondering if I could get a standard P38 rad recored to reduce the height. Width is fine🤔 Quote Link to comment Share on other sites More sharing options...
