They have this one in stock if you want Good.
FLX67100

Cost is only just over 500$ if you get someone to take your $ and give it to you at cost. I think Griffin makes this rad for them...

or drive to lake elsinore for a great rad.

and a 1/3 of the cost...

why do you need something fancy? anything more than stock for a stock engine is a bit of a waste IMO. If it's overheating, it probably just needs service.

I got a napa radiator a few months ago cost me $106 and lowered my cooling temps but I'm pretty sure my old one was clogged

 

[mako my day]

I replaced everything with oem . Still overheats when going over 50 mph or uphill, or anytime the engine is working at 35% or higher.

 

[eflosd]

Yeah I had that same problem I think the radiator mainly solved it, taking out the a/c condenser helped also (a/c never worked). Your sure your temp sensor for the garage is reading correct? Mine reads a bit high I use an obd scanner to verify my temps.

 

[mako my day]

I also scan with obd ii to watch temp. My.goal is to also run with ac on. High flow water pump $104 at 4wheel parts. Ill start with that and a tranny cooler/gauge

did you do a zj fan clutch?

High flow water pump

high flow does not mean high cooling. if yuo don't have mods like a stroker or forced induction that are creating excessive heat you do not need a high flow pump, you end up pushing the coolant through the radiator so fast that it doesn't have a chance to be cooled.

 

[mako my day]

V8 fan clutch . Tstat pump hoses rad exhaust header all oem. Less than 500 miles on it all.
Overheating under high load. Idle or downhill no problem.

Seemed logical to me since the oem parts don't seem to be working under high load.

After high flow pump, then 2 row aluminum, then onto exhaust system, then too craigslist.

Verify that your elect fan is working correctly also. A newer 10 curved blade elect fan is nice. But yours should be that style being the newer year.

It took me 6 caps to seal on the rad right.Take it to a good rad shop and have them look at it.They'll help you if you ask.This is how i found a great shop out here.

 

[eflosd]

Flush the system ?

 

[Ronbo]

Did you check belt tension?

 

[mako my day]

Flushed clean.

And shes tight yo.

I was having same problem even after I changed cracked head three weeks ago just got back from doing mojave rd. My temps now around 190. Changed 1 year old leaking 2 row CSF for 105 dollar autozone put spring in lower rad hose auto zone 180 tstat with hole drilled in it and autozone rad cap. This is the coolest it has ran since I bought it. I have bought 4 tstat napa, dealer, Robert shaw and auto zone guess what autozone one has the largest opening. By the way autozone one is called motorad. Also changed back to standard clutch fan.

 

[Camping350]

So I have for sale a 1 year old 2 row CSF with small leak 3 thermostats and a Napa ZJ fan clutch.
