New here! Ok so I have a 99 Toyota land cruiser v8 4700. Recently at cold or hot startup the engine would revup loud. Fan kicks on immediately. Put in drive and getting out of 1st gear it would rev up to about 2700rpm but sound so load like a 84 Toyota. I would slightly let off the gas and it would immediately quietly down and shift fine afterwards. I looked it up online saw something about disconnecting the negative side of the battery for five minutes and it should reset the TCM transmission control module. I did that and it did quiet down alot but I can still tell its not as quiet as it was and getting out of 1st gear still took a tad bit longer. Took it to a mechanic, I assumed engine reached temp because of the distance getting to the shop. Mechanic told me to turn it off pop the hood. He immediately tried turning the fan blades and they seemed locked or had alot of resistance. He then said " needs a new fan clutch"
I told him I'd buy the original part and return to him.
I went home looked up fan clutch issues and found how to diagnose a fan clutch. Here's where it's confusing. I found many conflicting opinions to what the mechanic did in testing my fan clutch. So let me explain the test I did on my 99 Toyota land cruiser. Early morning engine is cold I attempted to rotate the fan blades. Lots of resistance no spin at all. Checked for leaks around the clutch fins and barrings and they were clean. Started the engine did the paper test and paper did not stop fans rotation not even slightly. I turned off the engine and fans stopped immediately.
So did I do the correct test for my 99 Toyota land cruiser ?
Is my fan clutch bad ?
Or what should else should i check ?
