Heavy Duty Radiator

[KW1985def110]

I got milk last night and grocery’s today, zero axles broken.


DPdotCom - please let us know how the shroud works out for you once installed. I’m planning to do the exact same as you once I get to it on the to-do list

I'm going to do one test cut in cardboard this week, and then order it from SendCutSend and then I'll send pictures. 2MM Aluminum cut and folded from SCS is only like $80, so even if i have to do a second version, it will be a hell of a lot cheaper than a whole new rad, or even anything i could buy. If it works well, I'll happily share the file, unless @Z.G wants to sell 'em for me

First version I'm going to leave out the mounting points and then drill them once i have the piece bc i'm not as confident about where things will line up after the bends (K-factors, bend radii, and length-to-bend-radius stuff is putting my brain in a pretzel.) After I do the first one I will definitely have accurate drill points and such to add threading for the fans too. So this is a long winded way of saying that version 2.0 could be a slick product or freebie to offer to folks with the Revotec kit.

Wait, we are back to discussing heavy duty radiators? Where's the fun in that?

Did they ever reach a consensus of which one of their dicks was bigger?

Talk about bigger isn't necessarily better. I recently purchased a 95 TDI that had this Alli Sport XL radiator in it. It was leaking and it was warped like I have never seen before. I'm not knocking Alii Sport cause I don't know what caused this. They produce great products but I would like to know what would have caused this. Over heating is one thing but I've ran cars hot in the past and have blown head gaskets but never a blotted and leaking radiator after the fact. I purchased a stock size radiator and it works fine so far.

I've seen one other allisport expand like this. However, every other one that I've seen has been Rock solid.

I'm running a Chinese 300 TDi Knock off from eBay now that's standard width. It needed very minor adjustments and seems to cool relatively well. My issue around cooling was here in Vegas when it's over 110 ambient with the front mounted intercooler I could not get my temps under control. Even with the boost in the mid twenties I was still creeping on the highway.

I decided that longevity was better than performance and moved to a stock width 300tdi style intercooler and kept the boost high. I still run the electric fan relatively often, but I can be at highway speed now Pulling hard all the way up into 120 ambient without creep.

I'd say the biggest enemy that most guys will have is a bad tune. Run if you don't live in an extreme environment, these engines run cool

 

[gerken]

Yeah... I totally give in.

My head studs aren't branded and anodized to match my thong, so it certainly isn't me. Maybe some day I'll get to run part of a dirt track and be cooler than the underside of the pillow.

We're fully back to radiators.

 

[UnfrozenCaveman]

Not fer nuthin, but I found this o.e. (1994) really poor condition rad in my garage.

A local guy replaced his years ago and I've held on to this one ... I have no idea why...

If anyone really needs it let me know ... ships from 50265 on your dime and I'll even wrap in some super fancy cardboard for the trip

Holler if you need it ... did I say for free ... and I'll send it.

For what it’s worth in this rather divergent thread, my “overheating” problem turned out to be a blown head gasket. When your coolant is “boiling” and shooting out through your reservoir cap, your engine must be overheating, right? Nope! Make sure you’re not dealing with a blown head gasket before you start replacing your entire cooling system without solving the problem. If you’re having what presents as overeating problems, get yourself one of those coolant “sniffer” kits that checks your coolant for engine compression gases so you know for sure. The funny thing about a blown head gasket is that eventually enough coolant will be lost through overpressurization of your cooling system and you WILL overheat, very quickly and catastrophically. Beware!

Also for what it’s worth, I’m a fan of keeping things stock. I have a Wolf 90 with the stock 300tdi. The Wolf came from the factory with the heavy duty all-brass radiator as sold by RN. My original radiator had some leaks that I could not fix, so I replaced it with an all-brass replacement from RN. Very nice. While I was at it I replaced the heater core and all the hoses to ensure I was starting fresh. I live in Tucson, Arizona where summer temps get above 110 several days each year, and above 100 for weeks at a time. Mine’s a daily driver, and once per year I take it out in August for a four-day camping trip near Yuma with a buddy of mine for our annual Heat Treatment adventure. No AC, and last year it got up to 113! Let’s just say we spend a lot of time looking for shade and sitting around drinking cool drinks. 220 miles each way on the freeway and about 100 miles tooling around off-road. She runs cool as a cucumber. The stock cooling setup works just fine, but if you try to make your Land Rover into a hot rod I can see how you might run into problems.

On another note, I also added RN’s excellent VDO speedo and 3-gauge setup (speedo, fuel, volts, temp). They hooked me up with 24-volt gauges for the Wolf. Pricey, but awesome. The stock temp gauge sucks weiners (since we appear to be on the subject of weiners), and the VDO gauge actually tells you what your coolant temperature really is in degrees rather than the nebulous when-should-I-start-to-worry stock gauge. I never get above 210, even in all that heat.

That’s what’s worked for me. Your experience may vary!

I really wish this came with a tach option. I don't need volts in my line of sight in the primary dash spot. It's the only thing that's prevented me from going this route.

But on this topic, I'll be pulling the fans sometime in the next few weeks to get some perfect measurements, then comes cardboard-aided-design step, and then I'll order the aluminum one. I know y'all are waiting with bated breath to see this

We can include a tach, we just cant figure out how to get it to work 🙃

shroud 1.0 is in progress at SendCutSend

 

[DPdotCOM]

alright folks, took two SendCutSend jobs, but I think what I came up with is pretty much perfect if I do say so myself. The fit is shockingly good. I converted the cheapo connectors Revotec uses to Metri-Pack while i was at it, bc I've had connection issues in the past. Won't ever happen again with a properly crimped metri-pack.

Weather stripping all the way around, and eventually added to the little tabs on the bottom as well to make a good seal and a more gentle place for the shroud to contact the radiator. With the right placement of the holes for the top pins and the weather stripping on the bottom tabs, this thing doesn't move one single bit, it's as locked to the radiator as the revotec bracket was, if not more.

SendCutSend is a pretty magical business. Given that it's my creation, I don't mind showing off the bright aluminum, but this thing would look awesome powdercoated in black or wrinkle black.

I was planning to put 1/2" foam weather strip between the top flange of the shroud and the radiator, but the fit is so so good. I probably need to add some gasket at least to prevent galvanic corrosion, but would value input here.

Remains to be seen how much of a difference this will really make, but I'll be on the beach in a week and I'll give a report.

Yea, but it is one of the worst things to happen to this thread.

I came to see if these thick hogsman were going to measure from the top or the base, and now here we are back to technical content.

All kidding aside, that radiator setup looks great. If those fans are worth a damn they should keep that 3.5 plenty cool.
