Good evening all,
Almost ready to mount the incredible Wix 57401 filter into my Toyota Tundra. Have made a bracket, gathered up the right fittings, bought some Thermoid transmission hose, and bought a variety of OEM-style spring hose clamps. Even made up a fitting for putting a dial-type pressure gauge on the inlet side of the filter to check input pressure. (differential drop across the filter would be better, but the LubeGard mount only has a high-side pressure port)
Initially, I had thought about plumbing this filter in parallel with my cooler. Then, looking at the low pressure drop ratings of this filter, I decided to plumb it in the inlet line to the cooler.
Then I got to thinking - what's the only spec I've not checked? Answer - maximum temperature rating of the filter. It is designed as a tranny filter for an Allison tranny, but did Allison plumb it so it was getting 200 deg F ATF?
I don't know. I know the fluid in the Tundra will run at 200 deg F, as the fluid is plumbed from the tranny through a water-cooled (and heated!) heat exchanger. It heats up the fluid in the cold and will cool it a bit if tranny oil temp exceeds coolant temperature. I assume the thermostat in the 5.7L engine is around 200 deg F - so I'm guessing that's going to be the operating range.
I've got access to several K thermocouples and a dual channel reader and plan to mount the thermocouples on the cooler input/output lines to confirm/deny my 200 deg F suspicions.
Anyone know what temperature rating a 57401 might be good for? I've e-mail Wix in the past to no avail...
Perhaps I'll just plumb it after the cooler and not worry about overheating it.
thanks,
ben
