Hey all,

Was having a check under the lid today, and noticed cracks all through the thermo fans just on the part where its mounted, see picture below...

Obviously i will replace this asap, but for future reference, does anyone know why this happens? maybe linked to another problem or just general age?

Cheers

v.common problem...180 nzd for my turbo fan replacement from nissan....prob due to the different thermal expansion differences....metal hub expands more than the 'plastic' fan and puts stress on the outer ring. place some witness marks on each crack to confirm if they are moving if you cant affornd a new fan... its gonna get real expensive fast if the fan lets go!
