yes friend I have an ultra scangauge and out there monitoring I haven't seen it in more than 194 but I still don't use it daily but a few miles a week... and an electric auto meter gauge to monitor oil pressure

 

How did it go or what configuration do you currently have?

 

I am the OP of this thread that I previously posted:

See post #11:

A quick update with the 2991 fan clutch...simply awesome. 3 days of offroading. Climbed to 2000-metres. Hardly broke a sweat. 174F to 179F pretty much all day. Went up to 188F after a long climb. Then settled down quickly to 179F. The fan hub does sound like a jet turbine engine when under load though. But no worries at my end to have the cooling peace of mind.

 

It is incredible that it works so well… if that is what I am looking for since the problem with these trucks from what I have been able to investigate is the high temperatures…. I am going to make that small investment, the sound is what worries me the least, I also thought of electric ones but that would be more cumbersome for me

 

Well, I'm here to share my experience, after changing the fan and blade recommended Hayden 2991 fan and Dorman 620-112, with bypass thermostat 180• new water pump, new radiator, new nissens coolant, zerex G05. and today i went out and did about 100 miles with the air on and the temperature stayed 180 to 188 and i stopped for about 10 min and it went up to 200. i live in florida outside temperature 91• i think something is wrong. that fan sounds like a turbine


what could be happening or what could be wrong? oil pressure relatin 25 psi at 2000 rpm 50psi

help…

 

@Toms yup that combo is loud but it works - after a long hiway drive when you stop at a light the temp will go up, if the air is on even more. Ac seems to add about 6 to 7 degrees to engine temp on average.

 

I'm not seeing a problem here. What do you not like? The temps are fine.

 

The temps look fine to me. The 2991 is the severe duty version of the fan and it does cycle more often and does sound like a turbine. But it does provide more cooling for the radiator.

The temps will climb slowly if you truck is not moving and idling. I was getting 179F to 183F when moving (ambient temps around 85F). It will climb to the 188F to 197F range when I am idling for about 10 mins with the aircon on (aircon running around 64F to 68F).

 

Thanks guys, I thought I still had something bad out there. because I have seen here that the temperatures work at a maximum of 180 but I don't know under what parameter of conditions, I am going to try with the original fan to see the difference. another question instead should I consume more gas with the 2991?

 

if I was in doubt if the temperature ranges were right. Thank you
