KlassicMotion Posted July 8, 2013 Report Share Posted July 8, 2013 Details: 1971 510 2dr Sedan with stock 1980 L20B Champion Aluminum radiator 3 row (3 core) These are commonly found on eBay for $225 shipped Part number: CC487 Here is the manufacturer's website: http://www.championradiators.com/ I've had this on now for about a year with no issues. Easy Peezy. The first thing you will notice when you put the Champion side by side with the stock radiator is the stock unit has a metal flange on the sides that sits the radiator at an angle, and it straddles the metal lip that lines the opening in the core support (or radiator support) for the radiator. The Champion does not. No big deal. Here is a shot of the mount on the original radiator: Slide the Champion down and hold it against the core support. The first thing you will notice is the core support has a metal lip about 1/4 inch around it. The side lips are fine, but the top lip needs to be massaged up, or, in other words bend it upward until the radiator sits flush against that lip and the two on the sides(about 1/6"-1/8"). Here is what it looks like before bending the lip upwards. You will also notice in those pictures you will need to shim the gap between the core support and the radiator. Use whatever floats your boat. You will want it to be hard mounted i.e. a metal shim, or hard nylon, etc, not rubber (in my opinion). I used the tried and true method of using washers, which actually worked perfect. 5 washers on all four bolts was perfect. If my memory serves me, I used four 5/16" grade 5 hex head bolts about 1.25" long.... I will be changing them soon, because they are not pretty enough for me. (I was towing the car on a trailer, and all I could see in my rear view mirror, was the four shiny hex head bolts glaring at me throught the grill...) I'm going to swap them out for some phosphate coated metric button head bolts with Stainless nuts (you've got to have shiny nuts!). The Emisions Control Relay won't just bolt back on in the stock place. You will have to hog out the hole to get it to fit. Next, just tighten everything down and hook up your hoses.... The stock fan shroud will not fit the L20B plastic fan with clutch.... Without modification. I haven't started on that mod yet, but thus far I haven't had any issues with overheating, so I'm not sure it's necessary. Quote Link to comment
jrock4224 Posted July 8, 2013 Report Share Posted July 8, 2013 maybe a link to the purchase place too..... the last one we installed we spaced it out more and used some pinch weld molding on the lip you pounded down .... and installed two pusher fans....not sure this method would work with the stock clutch fan .....but a option of r using electrics... car doesn't run yet so no verdict on the 2-7" pusher fans and there effectiveness but will add when the car is done....well that is if we still even use the internet by the time the car is finished Quote Link to comment
Dawa Posted July 8, 2013 Report Share Posted July 8, 2013 nice. i got one of their rads. its actually made by their "sister company," american eagle. one is 2 rows, the other is 1, but they equal about the same surface area and champion/AE will tell you that they cool the same. one thing about spacing the radiators out, it is most beneficial to seal the space in between the radiator and sheet metal, as air will take the path of least resistance... an ugly but perhaps effective way would be caulking or something similar. or that foam tape.

Dawa Posted July 8, 2013 Report Share Posted July 8, 2013 also, i got mine from ebay. find out the part number and then find one of their dealers that has it for the cheapest. bought it for my 73 620, which does not work (even though THEY say it will.) 510 and 610 rads... one is taller and the other is wider. i can make it fit but i have to cut some metal or somethin like that. havent worked on it yet i just wanted to see if i could make it mount up real quick and maybe just drill some holes Quote Link to comment

metalmonkey47 Posted July 8, 2013 Report Share Posted July 8, 2013 Looks like a good fit and nice install. Great looking radiator too. But uh.... fram oil filter? Quote Link to comment
jrock4224 Posted July 8, 2013 Report Share Posted July 8, 2013 ah ok. sorry, i wasnt familiar with the term 'pinch weld molding' off the top of my head >< more commonly referred to door edge guard in the auto body world.......i never used it on doors though..comes in black , chrome and clear... I always use it on exposed sheet metal edges in projects i have done....i use the smallest stuff for sheet metal .. i think its 1/4 and 3/8.....they also sell it in a l shape instead of channel i always use the channel...u can cut v's out of it and it wil do 90's ..... has a little bead of adhesive down in the channel too......if your still head scratching ...next time u see the vato zone jc whitney chromed out truck thats local to u ... look at all the gaps ... they like to use the chrome door edge on hood edges, fender edges , tailgate edges, window edges, edge edges.....apparently it goes well with the chrome mud flaps they purchase.....like i said i use it outside the spectrum of its intended use...one time on a home made pvc bong.....made a perfect mouth guard on one end.... 1 Quote Link to comment

Stoffregen Motorsports Posted July 9, 2013 Report Share Posted July 9, 2013 Looks like a good fit and nice install. Great looking radiator too. But uh.... fram oil filter? Here we go again. Quote Link to comment
KlassicMotion Posted July 9, 2013 Author Report Share Posted July 9, 2013 But uh.... fram oil filter? I pulled the engine out of a truck that had been "sitting for a year". I'm only running it to flush the engine. I've got 100 miles on it since the pictures. I'm pulling the head tonight and replacing the head gasket. After everything is back on, I will change the oil again, and run a Mobile filter with either Valvoline or Castrol 10w30. Quote Link to comment
0r0B210 Posted November 14, 2013 Report Share Posted November 14, 2013 Where did you find that Radiator Fan blade? I cannot find one for my B210 (1976) anywhere. Thinking of adapting a 280z clutch and fan since those are plentiful where I live, because I cannot find the fan blade for the clutch that belongs to my 1976 B210. Cool pics. Quote Link to comment

It's just a stock 1980 720 L20B. One option that I've been having success with; go on eBay, search for Datsun 620, or Nissan 720, under the parts section. You will find salvage yards listing parts of vehicles. They typically have a picture of the entire truck. Give them a call, or sometimes they have a link to their website, where you can make Internet purchases from. See if they have your fan..... Or check your local junkyard or Nissan Dealer.

KlassicMotion Posted November 14, 2013 Author Report Share Posted November 14, 2013 Some companies have good products, but horrible customer service.... Maybe this is the case. I love my radiator. Quote Link to comment

I have three ...two cores leek like sieves...the one in my truck is a small leak the one for my good is a fucking water feature... water sheets down the core... This was the exact reason that I didnt buy a Champion/Eagle unit. Their quality is so hit or miss... Spent the extra coin for that Koyo and am so glad I did. Quality is phenomenal. Jon, hopefully you get your shit sorted. Quote Link to comment

KlassicMotion Posted November 15, 2013 Author Report Share Posted November 15, 2013 Lucky...jaja. I think he wants you to measure your mounting holes in the fan, so he can check for you when he is there..... At least that's how I read it. Quote Link to comment
flatcat19 Posted November 15, 2013 Report Share Posted November 15, 2013 Yes. Hole to hole and size of hub. I have a couple of fans here. Quote Link to comment
