Standard or hiflow thermostat for 02 gu td42t

[mudski]

You replaced only the fan as the G35 fan fits the TD viscus correct?

Hey Robo. I replaced the fan with the G35 fan, it fits the GU hub, not the GQ hub, added more oil in the viscous hub, and put in a UFI radiator. I also put in a high flow thermostat. Not sure if any of this has helped yet as its still too cold here to tell. One thing though is the fan certainly pulls more air than the OEM fan. As on start up when the fan is engaged, with the bonnet open you can really feel the air from the fan. One thing I am not sure of too is whether I have put enough oil in the hub, as this is supposed to make the hub engage earlier, being so cold here at the moment it hasn't engaged any earlier. Plenty of other people who have done this have said their fan is engaged pretty much all the time, mine isn't so I am assuming it just needs more oil. So I might have to take it off and put more oil in it. But I will wait until its warmer here first.
After speaking with a few radiator mobs and a couple of mechanics that do a lot of TD's, air flow is more important than coolant capacity. Sure capacity helps but they need more air flow. Also I will add just adding the fan and not modding the hub you will more than likely just be wasting your time. Because when the hub disengages the fan won't do anything. So you need to do both, or just the hub in my opinion if you want to see any gains.

Cheers.
Mark.

All good info, thanks.
I'll try adding some oil to the hub.
As a matter of interest the (toyo) oil comes in 3 different grades,
to lock the hub up at different temps I presume.
Is the g35 fan the type on ebay listed to suit 02/03 models?.
cheers

Got a link for the fan? As for the oil, not sure of the grades, I just bought two bottles off the one that everyone uses part number 08816-10001, 18ml bottle, and used 1 and a half of it. I did drain out what was in there, albeit not much but I think i need to add the rest. Just not looking forward to removing the fan and hub with the rad in.

a link, table on various grading indexes and compares them @ 40 & 100 deg C.

toyo oils available.
08816-03001 = 3000cst.
08816-06001= 6000cst.
08816-10000= 10 000cst.
web search, apparently 3000cst is used in cooler environments.
and from what I've found the consensuses is to drain, clean & replace with fresh stuff, as the oil will lose it cst rating with use.

cant bring myself to type that word toyo@#, like swearing isn't it !

This seems to be the oil to use according to many other users on the interwebs. I did drain my hub out first, but I still think I need to add more. Time will tell....
And thats the fan I used.....

I've always thought that you needed to use two full bottles.

Why didn't you, playing it safe or won't it fit.

I bought 3 x 18ml 10000cst and only initially used 2 but didn't feel any difference. I recently had my engine out to fix a coolant leak so I redrained the hub and put 50ml in. Seems a bit stiffer but it's not hot enough yet to really test.

The G35 fan is the same outer diameter as the std TD fan ??.

Slightly smaller in diameter by a poofteenth. Thicker and larger blades though.
