Over heating again

Ok i think I have replaced everything I can but the Radiator...

I have replaced 3 T-stat. 2 Caps, coolant/water/waterwetter.
and rebuilt the fan clutch...

When it get hot or the truck is under load, it starts to over heat.
I toss on the heater and things go back to normal...

I am 99% sure the Radiator is now blocked and clogged and just can not disapate the heat any longer.

So who makes a good radiator?
i know the single Row OEM unit did great for 11 years and 116K miles.

Did the v-6 and 4WD drives have a larger 2row? if so will they fit?
I sorta think they will not.

I see Radiator barn has 2 choices.
a signle row an a 2 row about $40 differance in price.

is $180 a good price?

 

The 2 row will keep you soooo cool... for $40, I would do it in a heartbeat if you plan on keeping for a while.

 

LCEngineering sells a Nice Aluminum Rad for you trucks.

 

LCEngineering is the shit. But a bit pricey. The quality is there though.
