Some of you will remember when I had my rad built a couple months ago. Well, summer has fully arrived here on the west coast, and it is HOT! The temps have been around 30* celsius all week, and humid as hell.

I was out and about today, when I decided to stop for a McDonalds burger on my way home. I got into the drivethru, and then it stopped. Something was wrong in the McDonalds, and I ended up idling in the blazing 32* heat for over 20 minutes! Temp needle barely went over half! That would NOT have happened with my old stocker!

...And I still love my sotck two core. Its clean and the motor is dialed in. It has not gone over half in 100 degree + temps, took it to Palm Springs in the middle of summer w/ no problemos. The two core is not inferior and I try and tell the 320 radiator boys the same thing. Am I the only one that feels this way? No overheating drama ever with the stock unit. Another thing to throw away money on your 2002 IMO. Sorry AL but had to vent, I AM glad your cooling issues are good! Was you two core really that bad? Perhaps it was just a POS to begin with? Is it worth the $$$; how much was it? Thanks, -A

I agree to a point. My 72tii had a stock 2 core, and it always cooled OK, even in the hot hazy, and humid conditions of Southern Ontario(humidex of 40 degrees some days), but it got me nervous on more than one occasion!

My 74 had a 320i rad from a PO, and it always cooled great. My 76, got WAAAAAY too hot last summer. I found myself driving with the heat on high sometimes, when stuck in traffic, and it still got dangerously close to red.

Basically, it was hooped anyway, and needed some work. It was gonna cost me $165 for a recore, using 2 core, or an even $200 for a 3 core. Not too much more money, and a whole lot of peace of mind. It also came with a lifetime warranty! Was it wortgh it? ABSOLUTELY!

i have been through several "heated moments" over the years with the cars, and nothing gets my adrenalin running worse than a fast overheating 2002 on a hot day in a clogged traffic jam with no place to escape to and get some air running over the surface of the rad. Just puling over and shutting down is the only option, but it can still lead to head gasket blow, or worse. I hate hot running cars! So, I became very particular about all cooling components, and I spend what it takes to keep my engines in the happy zone ( or am I keeping me in the zone... well, same/same). In my Sahara I replaced a shot 2 core with a free 320 rad. that finally died. I replaced it with a 320 clone- all metal- and cheaper than Behr, from "Radiators 911" 5.00$ shipping anywhere the usa. It is a perfect clone of a metal/plastic 320 and it is all metal and painted gloss black. It is combined with a 71 degree thermo and a 320 aux. fan.The water pump is new with the rebuilt engine last year. I dont have to worry about that car any more( although a hose-1 of 2 that did not get replaced- went the other weekend when my friend was driving that car to the Palo Alto 2002 meet- he never knew it was leaking, but I saw the splash marks and smelled the coolant from the little leak when I inspected the engine bay after the weekend event.(hose to heater- hard to find, 20 bucks from dealer).The Inka tii has a Turbo Rad. that is going to get recored by Curt Ingraham of Berkeley, and it has a 75 degree thermo and an aux fan too. That engine is getting an oil cooler by Korman that i just bought on ebay. The Turbo Rad. has always kept the car cool even on summer track days in the middle of the California hills- but I want the new engine to have an oil cooler and the time to do it all is during the transplant. I just have to much invested in these engines: I try to protect them as much as possible. There are always things to listen for,smell,feel and notice when using a 30 year old car for a daily driver- I like to eliminate as many potential problems as I can- so I can be ready for the next system that requires attention. Sorry for the rant, but I can remember every damn time I have been in the red because of some component that decided to die, and I dont like that feeling at all. Keeping cool in Nor Cal...///

My car ran hot with the new motor. With the new motor I was looking for all the "extra margin" I could get. Wild paranoia...perhaps, but with the 3-row and VDO's, I'm much more comfortable. Is it worth it? It's hard to enjoy a drive when all you can look at is the temp gauge. Congrats on your car being a cool runner!

...I used to fear traffic. There has been a few occasions were I had to pull over and let things cool down even. I tossed a radiator from a 320is I had acquired for various parts (hadn't even thought of the radiator). I had to because I stupidly started my engine before checking fan/radiator clearance after my five speed conversion. Crunch! Boy, am I glad that happened. My car runs cooler than ever now with the E-21 rad w/electric fan. Is a perfect 02 radiator adequate on a car that has no cooling issues. Of course. But, if you have to replace the radiator anyway, why not uuprade what is considered by many to be a weak link.

So. AZ, with temps 38-40 C (105-110 F) My car runs nice in cool with the A/C (obviously, in these temps) at full on. My A/C hasn't been touched in six years and put out 42 F air from the vents (Behr, w/ 22 yr. old Sanyo rotary compressor). I think the thing with radiators is not so much the number of cores, but the age of the unit. My son's '74 runs a Curt Ingraham 3-core and runs @ 1/2 on the guage, or below, in all temps. FWIW.

There I am thinking of fitting a 3-Core Radiator upgrade to my Tii, when I notice you've already done it.

Yesterday stuck in traffic the Electric fan blow a fuse, thank God I left the original fan fitted, but the temp

started creeping into the Red. My Radiator has some of the cooling fins damaged (not sure how) so I

doubt it's efficient as it should be. I want to replace with 3-Core unit but only if it's a straight swop - Is it?

I have a specialist that will be me one for £165, but seeing if I can source one from Germany first for less.

Just goes to show you, you can't rely on these electric fans - it's the second one that's let me down.

That's why I keep it as a backup to the main unit.

Still haven't tracked down those trumpets.

Found the Pipe supplier though - www.flexiblehoses.com go for the heat proof Wyram pipe 2.5" diameter.

Bob is correct -- the age of the radiator is the key. (And coolant flushes every other year extend the radiator's life.) All radiators deteriorate with time, and most of our '02 radiators are old enough to have served their useful lifetimes. If recoring, as others have said, a 3-row core is only a very small additional cost over a 2-row core. Finally, using a cooler thermostat (71 C vs. 75 C or 80 C) will NOT improve cooling or prevent the onset of overheating.
