I put a MSPEC radiator in my R33 in late 2007. Cooled really well for 4 years but it is now leaking from the bottom tank (where the tank meets the fins).

Just FYI for those with MSPEC radiators - these things don't last forever. I've done ~80,000km in those 4 years.

Any suggestions on which new radiator to buy? I'm thinking Koyo.

(Yes I changed the coolant, yes it was grounded - no obvious corrosion inside)

Well I considered repair but I thought it likely that this spot might be fixed then another go somewhere else. Then again, I know nothing about radiator repair. Any idea what a new end tank costs to fit?

Bought a Fenix.

My MSPEC seemed to cool well. Never above 88°, normally sat on 81°

I currently have an Mspec too. Cools fantastic, perhaps a little too well. Generally sat on 78 - 80, 85 with the aircon going on a 38 degree day.

You retaining the stock shroud with the Fenix?

Idle with air con on and hot summer days I get to about 86 degrees with the stock radiator, 78 on normal days.

I needed a new rad, and at the time i could get the larger mspec for cheaper than the stock replacement, so i figured why not :)

But awesome temps you got there with the stockie :)

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
