The one linked at ID parts is 'composite' (plastic). The last Hepu I got was too...
ohhhhh that may be bad... see my suppliers tell me they no longer made cast ones years ago.. but few places could order/get them like 1 warehouse had.. rest had plastic.. we could not figureout why... i assumed old stock... maybe there is no more..
Hmmm. The top meyle part number is good as I have one in my car. cast aluminum it looks like, but I didn't put a magnet on it.
Lets see how long the meyle one lasts as their quality is poo. Maybe we should start looking into rebuilding the waterpumps ourselves.
Cast or stamped impellers are best..
plastic actually flows the best, but they dont last the best...
