Boycott Amazon and eBay.... or buy at your own risk.
I will only purchase parts from a known Toyota parts dealer.

What is the difference between FCT-049 and FCT-017? I have a new FCT-017 and potential overheating issues. and I have not driven it enough to hear the roar, it overheated on the maiden voyage but that might have been user error and a burping issue.

Update. And Went ahead and ordered the FCT-049. Did some searches. Haven't heard the FCT-017 spool up yet. I can possibly take apart the FCT-017 and use my RC shock oil and try a different viscosity later.
Where did you order it from?

It should be blatantly obvious if your fan clutch is engaging. The OEM Aisin fan clutches will nearly free-wheel when the engine doesn't need cooling, but when they heat up, they engage HARD. The fan absolutely roars. I have a magnaflow muffler on my 62 (not a particularly loud muffler), and if you rev the engine to ~2,500-3,000 RPM the fan is FAR louder than the exhaust.

Here's a good video demonstrating how loud a mechanical fan can get when locked up:
If you're hitting 230-240*F and the fan isn't that loud - then either your radiator is plugged or your fan clutch is bad.

Wow, mine has never done that. New fan clutch it is! I'm feeling pretty good about this!
