....my left, right, middle wasn't accurate...they're there somewhere, lol

 

Here's pics of my block, for those that don't know.
You can see the threaded hole next to the serial# on one side, and the plug is still in, and next to a freeze plug on the other.

 

Well, got everything buttoned up today.

Replaced the WP, radiator and fan/clutch.

Taking out the radiator was annoying but not hard. For anyone doing a radiator swap, i'd recommend threading in the course phillips screws into the new radiator before installing said radiator. These screws are the ones that hold everything together basically -- you'll see when you start taking things apart

MOVING on

I'd say there was something wrong with the old radiator for sure..

Engine side



Other side





I'd probably say that 30-40% of the radiator was mucked/blocked up -- It appeared to be oil but the oil coolers that sat right in front were completely clean so i dunno what it was. There was mud also. Temp sensor had a nice film of some build up on it, cleaned it right off and reinstalled it.

Old WP appeared to be fine, gonna keep it as a spare.



While changing out the pump i found a bullet and 2 ball bearings just hanging out on the exterior of the engine



Truck currently has distilled water / vinegar mix to flush out any remaining crap -- ran out of day light to bleed it fully so going to do that tomorrow.

 

It's amazing how much crud builds up on the fins of the rad. I spent 30 mins with my hose clearing it all out. I was also shocked at how much crud was inside the rad as well. I'm pretty sure that removing my rad and cleaning it out helped more than changing out the 190 to a 180 t-stat.

Now would be a good time to back flush your heater core as well

 

I guess i'm amazed at how much the PO didn't take care of the cooling system

Yeah, i gotta flush the heater core but I don't have access to a hose

 

Just thought i'd update this thread.. Still need some help

Went though the process of doing the HG job, heads were machined and everything was good to go. MagPie still was over heating after everything was buttoned up, i diagnosed the newish 180 tstat to be bogus and ordered a new Brit Part tstat. Just finished installing and still have the same result for the most part.

Started the truck, temps crept up to 215 and then i shut it off -- heat was on full blast and the air coming out was meh hot. I should also note that i installed a new temp sensor on the lower intake manifold while doing my HG job.

Busted out the thermo gun after i shut the truck off and here is what it read.

Ambient temp was in the low 80s, truck is parked on a slight incline with the nose facing up.

Top 3 radiator hoses were between 150 and 170
Lower WP hose was 135
Radiator: From the engine compartment side -- Top left 121 Top right 102 Low left 97 Low Right 95
Lower rad hose was 97
Tstat: Upper half was 138 and lower half was 104
Heater core hoses: Going in was 140 and coming out was 125

In contrast, here are my readings before i replaced the radiator, WP and tstat:

I shot the temps from the back side of Rad (the engine compartment side)

Upper left corner of Rad: 190
Upper right corner of Rad: 122
Lower left corner of Rad: 155
Lower right corner of Rad: 100

Upper cooling hose from bleeder T to Rad: 171 @ Rad and 140 @ T
T to block: 167
T-Stat to T: 178
Rad to T-stat: 114
WP to T-stat: 155

Expansion tank: 175
Heater core hoses were both 133

Things are cooling off now so hoping that MagPie will burp
