4x4 tow ratings

I understand the 2005 and up 4x4 Tacomas had 2 different tow ratings, 5000lb and 6500lb. Is there any way visually to know which your looking at?

 

The tow ratings are 3,500 and 6,500. 3,500 is w/out the tow package, 6,500 with the tow package. Factory tow package comes with a hitch, 7-pin plug, HD alternator and an oil cooler for autos. You can tell by visually looking at them by the sticker on the door jamb. The tow package equipped trucks will have a GCVWR of around 11,000# and non-tow package equipped will be around 8,000#. Also, you can just look to see if it's an OEM receiver but that can be added after the fact.

 

just a question like that, since it's anti-freeze passing through that ''oil cooler'', how the hell water at 200degF can really cool down oil since it's about the same operating temp..?

 

Engine oil tends to run 220 to 250 degrees in normal op conditions. If it doesn't reach at least 212 degrees, moisture isn't as effectively removed from the crankcase. See the "oil fill tube mayonnaise' people see in the winter, especially on trucks used for short trips.

 

The cooler is on the return side it's been through the radiator and the water has been cooled. It's the same reason a transmission cooler works it's in the bottom of the radiator where it's cooler.

 

Thanks for the quick info about this guys, using hot water to cool down oil was bugging me, but it is now clear
