    Radiator woes.

    My aluminium radiator in the Dax keeps leaving traces of weeping on my garage floor, enough that once I finished my dashboard swap, the header tank was empty. The rad isn’t jetting water as far as I am aware but it needs attention.
    I have consulted a few radiator specialists and they have come back saying that repairing ally rads is not easy. Even the rad manufacturer said that. Price for a new one? £400+!
    Questions.
    Has anyone had any success with their ally rad being repaired?
    Can anyone recommend someone who successfully repairs these things?
    Has anyone got a ‘spare’ rad, ally or otherwise that may be for sale? I would rather recycle a radiator than buy a new one!

    Cheers.
    David.

    This is a radiator place in Nottingham which some members have used for a custom made rad at very reasonable price.

    They sometimes start to weep where the cores go into the tanks. I have found this worse on the ones with the resin.
    If it’s weeping at the ends I suspect it will be cheaper and better to get a new one.

    Yup! Thats it. Resin present in a few places on the radiator. A little disappointing considering the cost of these things.

    After my initial posting I did a little digging and found radiators for Nissan 200SX are widely used. There seems to be a choice though of S13 or S14. S 13 on paper seems to fit the criteria for cores and thickness but from what I read the S14 has been more widely used, unless someone can correct me?
    Also the S13 is available as an assembly with shrouded fans incorporated. The idea of fans being mounted directly to the rad core with plastic zip ties never gelled with me as you essentially damage the cooling fins on a brand new shiny component.
    What have you guys actually fitted out of these two rads?

    Cheers.
    David.

    I’m probably not the one to ask, I run a big block and hence a full race radiator. It’s Afco. Harrison Racing supplied

    This was the rad I ordered for Ford correct outlets.

    https://www.ebay.co.uk/itm/3-Row-Alu...AAAOSw7pldHfPQ

    The postage has gone through the roof since Brexit. The rad is the right size for Dax but you need to do some mods to make it fit for brackets.

    Core size 17 1/8'' high * 22 1/2'' wide*2'' thick

    The NISSAN S13 CA18DET MOTOR SILVIA 200SX 180SX S13

    Core size 638x360x52 [mm] overall size 671x490x95 [mm]

    Both inlet and outlets are on the right side.

    Common used Nissan s14 200sx correct outlets for Chevy engines

    Overall size 670 mm×445 mm×60 mm Core size 635 mm×360 mm×52 mm 3 rows

    Worth looking at a custom rad from Coolexperts in Nottingham. They do a 70mm core size.

    Thats really helpful. Once I get home I'll measure mine up then make enquiries as to how this rad is mounted.

    I would of used Coolexperts if I knew about them. I would of just dropped in my old rad for them to copy in aluminium. All mounts and size would be stop on and hose positions. I would have also added a top temp sensor thread. If you dont mind a bit of fabrication you can choose the Nissan option.

    The route of the bottom radiator pipe. It goes under and over.
