V6 Tow Package mandatory TRD Off Road?

.. Obviously.

The question is how many V6 trucks aren't being delivered with tow packages.

 

True dat. My mini van has a tow package

 

If you are right about the bypass valve, and if a bypass valve also exists in the engine oil cooler, then everything I said is wrong. But if there is no bypass valve in the engine oil cooler, I'm not so sure. According to what I've researched, the lack of adequate lubrication after starting an engine lasts far longer than the few seconds it takes oil to circulate. It continues until the oil reaches its ideal operating viscosity, which is at about 210 degrees. In winter temperatures, this can take 15 or more minutes.

You live in Dallas, where it rarely gets very cold. Since the efficiency of the engine oil cooler increases as the ambient temperature drops, when very cold winter air flows though the cooler, I would expect that the effect on oil temperature is considerable. After all, if these coolers are effective in summer, they must be that much more effective in winter. And in winter, driving under normal circumstances, the last thing you want is a device that is working to keep your oil cool and viscous. Again, if there is a bypass valve that that effectively turns the cooler off under these circumstances, then no problem.

 

Please share links to where you read that engine oil is only effective at 210F. My Sentra runs at 165F most of the time. The fans kick on at 203F and the thermostat closes at 164F. Why hasn't my engine failed in its 150k?

 

Are people talking about the standard tow package that comes with the truck. You know, the connector and the hitch? Doesn't the actual tow package option give you the bigger alternator, cooler and sway control. That's what I consider the tow package. But, the standard connector and hitch could be considered a tow package, right?

 

The tow package includes the tow bar and plug

 

So without the package there is no bar or plug on the truck?

 

A factory tow package includes the trains cooler, upgraded alternator, and everything else discussed here.


A dealership "tow package" could be a receiver and a plug.


There is only one actual tow package.

 

I never said that oil has no effectiveness at temperatures other than 210F. I said that around that temperature is where it lubricates optimally, assuming you have the correct oil in your engine. Your thermostat is operating based on coolant temperature, not oil temperature. The coolant temperature does not reflect the oil temperature. If it did, there would be no need for lubricant coolers, only larger radiators.

I have to go to work now and will be gone for two days, but I'll try to post the reference on lubricants on Tuesday.

 

Explain. The oil cooler on tacoma is fluid to fluid (coolant to oil heat exchanger), not air to fluid . So explain to me how coolant temp doesn't effect oil temp.

 

Oil is designed to flow in a wide range of temps. Hence the 0w 30, and 10w 40 designations.

That said, in general, it may benefit the engine if, upon warmup, you didn't place the internals under a heavy load until you reach operating temps. Especially in cold weather. But this isn't due to lack of lube, rather than material properties in the cold.

I'm not 100% if there a bypas valve, or some sort of restriction that permits better flow from a thinner, less viscous fluid with regard to the trans fluid. Someone more familiar may chime in for me here. Either way. Others here are correct. The radiator is for coolant oil for oil and trans for trans. The coolant is at a lower temp than oil so the fluid to fluid cooling is effective. I would also surmise that this could also help the oil warm up during cold starts by circulating warm coolant to the oil via the cooler.

 

If I have the correct multi weight oil in my engine, there should be no problem at start up other than starvation issues for a few seconds. We don't run single weight oil in our road vehicles. The extra oil cooler is not in the radiator. The oil cooler in the radiator is standard

As an aside, I run a fixed 80 weight in the bottom end of my yz250 because it heats up to one temperature and is bath only.

 

V6TowPackage
Option for V6 models Includes:
Class IV receiver hitch
Heavy duty oil and transmission cooler (with automatic transmission)
130-amp alternator (with manual transmission)
4 and 7 pin connector with converter
Trailer Sway Control

This is out of the Tech sheet. So with the manual tranny you do not get the coolers, only an upgraded alternator?

 

What is trailer sway control on this model?

 

Stability control/ABS system is used to help help truck stable

 

Trailer Sway Control is also on the last few years of the 2nd gens with Tow IIRC

 

The manual gets the oil cooler but not the transmission cooler.

 

Gotcha, thanks.

 

Manual trans don't typically get hot like a automatic. You don't have parts intentionally slipping that create heat

 

Posted a link below. This site is the best one I can find that pulls together a lot of information about oil and lubrication, though it is hardly a raw technical resource. The writer, who is trained as a surgeon, is also not the most organized writer in the world, but I think he does dispel a number of urban legends about lubrication.

I never said that coolant temperature could not have an influence on oil temperature. I did say that oil and coolant temperatures were not the same. If it is true that the oil cooler on the tow package is fluid to fluid, then my concerns about lubricant coolers are, at least to a large extent, probably not worth worrying about. But I still don't like that even in very cold weather, the engine lubricant is constantly being put through a device to lower its temperature.
