Hotter at 100KPH

[zander]

I recently adjusted my valves and found that they were very loose. After bringing them all back to spec the temperature of the truck dropped significantly.

Thats an interesting observation. What about the valve job do you think did this?

I will be tapping in the sending unit from the aftermarket guage.

Iron-giant, what else should I be doing as far as a tune-up goes at those KM'S?

Thanks

I'm still learning as I go but this might help a little. I recently adjusted my valves and found that they were very loose. After bringing them all back to spec the temperature of the truck dropped significantly. Mind you this is all on a stock gauge, but my 2h with similar mileage now never goes over half, and only reaches half under heavy loads. Before I adjusted the valves I was getting up to half and over on any small load. I am also running 33's and 3.73- makes for a very gutless ride. As stated above, with 35's I would definatlely regear to bring the 2h back into its massive power band. best.

I thought are very important have proper valve adjutsting .. must if are exhaust valves .. they afect the exhaust hot gases from the engine .. also if you put a header you can drop the temp ..

I thought the better grearing for 33" are 4.11 for overal use .. if you plan a lots of twing .. go for 4.56 ..

Turned out to be the set up I had. DO NOT WIRE AN AFTERMARKET GUAGE TO THE FACTORY SENDING UNIT........

I drilled and tapped the sending unit that came with the guage to the top of the stat housing. When the stat opens the guage reads 190*F which is right for the stat reading of 88*C. Went for a boot and the hottest the truck got under any load over 550*C for as long as 1.5min was 205*F and then it would cool to 195*F. At Idle its just under 190*F.

Tapage the factory stat here is 88*C unless there are temp options which I didnt ask. OEM stat.

Ill take pics later.

I had the same overheating problem with my 13B-T. I pulled the rad to replace it and eliminate that as a problem when I realized that it was plugged up. Before uninstalling the rad I had made many attempts to clean it and I thought it was pretty clean. That was untill I pulled it out. It took me $5 at the car wash to get all of the mud out of the uninstalled rad. All of the mud was hiding behind the fan shroud. I put it back in and haven't had a problem since.

My 2C's

I installed a turbo on my 3B and am getting EGT's at 1050 pushing really hard uphill at 6500 ft. altitude. I have noticed that my coolant temp is getting hotter I have adjusted my fuel out 2/3 and might back it off a bit. BTW, I run 295/75 R16 BFG ATKO tires 4.10 gearing
