Engine Temp.

I am curious what temperature your first gen V6's are running.Here is mine,does this seem a little hot or about average?

 

This maybe a good place to start:

That depends - what were you doing with the truck when it showed that temperature? If you were idling on a cool day, that's not good.


My 2002 and 2004 AC 4x4 V6's would show anywhere from 191F (cruising on the highway in moderate (85F) temperatures, to 197-198F heading up a long grade at highway speeds, or slower, on a hot day.


This was with 32's (235/85/16), an ARB+M8000 winch, a HiLift in the back and an ARE shell on top. Oh, and with a FROR rear bumper, plus assorted camping/hunting/fishing gear. I think once, heading from Reno up to Donner Summit in 95 degree weather, and towing an 800lb trailer in addition to the rest of the stuff mentioned above, I hit 202F.


Unless you had a good load in the truck on a hot day, heading uphill, I think 208 is a little warm. It's not going to hurt anything, since I think Toyota is OK with temps up to 220F or 230F, but I like to have as much room to deal with extra engine heat as possible.

 

Appx 93 deg air temp at idle..

 

Seems that after adding my tranny cooler it has gone up a few degrees.I guess the extra radiator blockage may have caused this.

 

I just have the temp needle.
I just bought it used and it runs a tad over half way to hot. That doesn't "feel" right so I had the radiator flushed and I am going to replace the thermostat and cap. They are cheap.

 

My engine temps from my UG range from 190 to 196 for the most part no matter where or when I drive.

 

Think I will change my thermostat and see if that helps..

 

My gauge on my 04 Prerunner V6 runs a tad over halfway and has been that way since it was new. I will post a picture when I drive it tomorrow.

 

I know this is a thread revival but 208 was my temp before I did the jiggle valve mod. On my UG I was running between 204-210 after reaching full operating temp. I had the thermostat replaced when I had the Timing belt done. I found out they put the thermostat in with the jiggle valve in the upward 12:00 position. After I rotated it to be in the 6:00 position my temps went down to 188-192 with it mainly stable at 190. It may fluctuate 2 degrees up or down but its way better than before. The FSM states that for the 3.4L the jiggle valve should be in the 6:00 position. I didn't think this would make any difference but it did, big time.

 

I know why it's running at 160 because the last owner must have put a 160 degree
thermostat in. I am going to change it to 180 because today I called that dealer and they checked the vin and it says 180.

But I kinda knew that already, I guess the question I was leading to, but must have been confusing , is will running at 160 affect the burnoff in the converter.
I can only assume that other things are affected by the lower temp but will they effect the converter, and bring about this catalyst system efficiency below threshold bank 1 420 error thing?

This is all brought on by a 420 code, which states that there is a converter problem.
My front oxygen sensor goes between .16 to .77
The back is .06 to 2.3 running at 60 mph

not sure what their suppose to be.
anyone know?

 

Sorry I put this in the wrong post.

 

I sit at 176.5 to 181.6
