2 weeks ago i replaced stock radiator with 3-layer one "Koyo". Also replaced 2 electric fans with stock jza70 hydro fan. (There were another oppurtuinity - to replace Aristo's waterpump with pump for JZA80, but it'll take bout 3 weeks for order)
Having no much information on this fan i made this:
- a switcher and relay for hydropump valve (i connected hydrofan computer later)
- a cooling line for hydrofan dextron
- small oil tank
So, at the first time, when i switch the valve, fan starts to rotate.. But sometimes it "sticks", and... i start engine again, open the hood, push the fan and then it spins...
2 days ago i connected the fan computer, tested it, it really works... But - fan sticks... I'm sure that pump makes good pressure, sure that fan spins easy on non-working engine, so only one decision i have - bad dextron or dust in the pressure lines.
