New radiator is running colder

Something lost in translation there my friend....

Butt injury!!

I guess so.... Thats when you try to sound like a cool bro with a cheap German school english...

Ok, i hope you get the picture out of your mind..

It made me laugh so it is all well. I needed a laugh today

This seems to imply that one can use this supplemental hose clamp to 'calibrate' the temperature at which one would prefer their truck to operate ... ?

It can let you know if any restriction of the hose makes a temp difference. How you use it after that is up to you.

Don't assume that the cluster gauge is linear or absolutely accurate -- it's designed to sit about in the middle of the gauge when the temp is normal, but the readings aren't absolute.

This is a well-documented issue with some aftermarket radiators. Lack of the restriction orifice in the fitting for the small return hose (to the surge tank) is common, and can cause over-cooling.

First of all, verify the coolant temp with a scanner reading live data.

Secondly, if it's running too cold, see this link and view the thread that's embedded in that post.

p0128 Engine temp below thermostat temperature/ strange O2 sensor values

Hello, I was just driving and suddenly the engine light came on. I read it at home and found that I had a P0128. This means the "engine temperature is below the thermostat temperature". In other words, the engine complains that it isn't warming up properly. Since the beginning I've had the...

Mine always runs at 210. Haven't put it on a scan tool tho

On the hose which runs from the top of the radiator to the overflow tank needs a nozzle in it to slow the flow. You can see the coolant flowing thru the tank. I used a 1/4 inch plastic cap off of a roll of copper tubing, drill a 3/32 hole in it. The flow to the overflow tank slowed down and temperature returned to normal.

Same results as if you used a small hose clamp that you could adjust as needed to make the flow in the hose smaller.

I would do that first. I searched my ass wound to find the problem and at least it was corrosion in the connector of the temperature sensor, which leads into a to low displayed temperature

see:

p0128 Engine temp below thermostat temperature/ strange O2 sensor values

Oh, well in that case, ignore my ramblings. Back to our regularly scheduled program....

I finally had a chance to replace the temperature sensor. There was no corrosion on the connecters. I put in a new Duralast Gold sensor. The problem is solved. Either it was a coincidence that the old one failed at the same time or loosing all of the coolant over a minute or two took it out. Either way, it was a cheap and easy fix.

So it was worth that i: searched my ass wound.,.

What size is the restricted hole size in the OEM radiator for the surge hose fitting? I wish to make a restrictor with the same OEM hole size to put in the hose end or in the radiator fitting of my new radiator.

I haven't see a measurement, but here's one solution from @Tozan's book of tricks:

07 Tahoe engine hot ac turned off

I am just saying a quick fix can be the clamp, like I suggested, but the washer tig welded in there should also fit the bill.

Might be MORE useful to find ways to make the restriction VARIABLE.
Whenever it's hot out, or whenever the vehicle will work or play HARD,
open it up some, keep things a lil cooler, to offset the powertrain's extra effort.
