XJ radiators, a review.
I’ve used the CSF 3 row in two XJs for at least 10 years with great success after struggling with high temps. One might have a leak (hard to tell if it is just the hose).
I’d be interested to see how the Aluminum cheapo holds up compared to others since you are able to provide consistent feedback. Glad to see some cool research happening on here again! Sent from my iPhone using Tapatalk |

Modine used to have a sweet 2 large core brass radiator that I would run in heartbeat but I think they switch to the cheap overseas junk years ago.

Re: XJ radiators, a review.
It's a shipping charge yes, you pay both ways for their failure. The rate goes up over time.
I couldn't even find a listing for modine.

Re: XJ radiators, a review.
Nice work.
Keep it up. I have a motor in Russ' shop and I am going to want a new radiator when it comes time to put in the motor. I appreciate you putting in the effort to help me make an intelligent choice.

I've been running the same Modine 2 core since 2003. I had it rodded and cleaned after ten years, still going strong.

Re: XJ radiators, a review.
OK, I got down to the CSF or Mishimoto unit.
In all of my reading, 'the experts' say it comes down to what has the most core/fin contact. More is better, period. So I started measuring. Mishimoto: 15 fins per inch 31" wide cores 1" deep core 26 rows 2 cores 15*31*1*26*2 = 24,180 inches of fin/core contact CSF 16 fins per inch 30.5" wide .437" core 25 rows 3 cores 16*30.5*.437*25*3 = 15994.2 inches of fin/core contact Running that through a calculator, the Mishimoto has 34.29% more heat dissipating surface. Even if you want to factor in copper being 20% more efficient than aluminium, the Mishimoto is still far superior. So we'll see how that goes tomorrow. ![]()

I have to agree, a crack like that isn't typical in aluminum -- I'm wondering if the bowl is compromised and going to leak right there Are there any other welds holding that crossmember to the bowl? |

I didn't notice the difference between 2 and 3 cores on the 2 you narrowed down to. I'll take the 2 larger cores over the 3 any day.

Re: XJ radiators, a review.

Re: XJ radiators, a review.
stress crack isn't it? didn't think they were that uncommon. weld shrinks but the base doesn't, but I'm rusty on AL welding.

Well, my math was fine. What I didn't take info consideration is that one radiator may have .003" of fin contact to the core and the other may be .005" of fin contact. Which he's right, I didn't consider. That lead into a long conversation about efficiency, fin design, volume, etc etc. After the discussion he thinks i should go Mishimoto as well (and by a large margin). Considering he designs high end intercoolers for a living, I'm have a lot of respect for his opinion.

Re: XJ radiators, a review.
I'm disappointed in the CSF.
The Mishimoto does look good, besides the cracked weld. Very good review of the options available. |

Re: XJ radiators, a review.
I’ve never seen a crack like that on aluminum, although I tig weld all my aluminum

Re: XJ radiators, a review.
I msg'd Steve at Mishimoto and invited him to participate in this thread. Seems unlikely he will, they haven't logged in here in over a year.
Wonder if I can track down his email addy.
