Finally had some nice weather to finish up the water pump, everything was good until I check under the car and saw the stupid elbow of the oil cooler is leaking. What idiot though having a 45 piece there was a good idea?? Anyway, in the meantime I had to yet again drain the coolant and im trying some high heat jb weld around it. I can't find the proper replacement for it that isn't some obsurd 500$. I was hoping that elbow was just a fitting but I don't think it is. Also why is the mobile version of this site a glitch fest?

i found theres another version of the oil cooler that has a bend instead of a 45 (21305-JK24B is the original, 21305-JK25B is the upgrade?) I'm not sure if the 21305-JK25B one will work or not but would make alot more sense to use if it does. There is also 21305-JD02C for a nissan nv200 (which is waaaaay cheaper) that uses the same size filter but i'm not familiar enough to know if the coolers are pretty generic aside from what size filter they take?

Ok so the nv200 dimensions are much smaller so prob wouldnt be ideal. Does seem like i tech could use any as long as it provides similar amount of volume andhas the ports going the same way as original
