The Devek radiator has the kind of bend at that connection that Ron is referring to. You have to cut the factory hose before the bend & then attach it.

Sean and I just fitted a 928 International Aluminium Rad to an 89GT.

I was a little apprehensive about the job having read the overview by Carl.

The rad went in absolutly perfectly. All hoses went into place with no problem and no tweaking.
Perfect fit at the bottom and the top. Rad came with all the correct seals to transfer fittings from the old rad to the new. Fan shroud fitted first time and we had no issues at all.

I will not hesitate to get more of Marks Rads andfit them to mine and my customers cars - much better improvement over the stock IMOO.

Thank you Mark for a first rate product.

Do you have any idea what I am referring to? The stock hose is plenty long enough since it now has to raise up and come down on the nipple. The way it is now it rubs on the underside of the hood (bonnet since you are in England) there is a clearance problem albeit a small one. This was actually pointed out to me by Precision Motorwerks and he has spoken to Mark A about the problem. It is also plastic so the possibility of it breaking is increased.

Yes. And stand by what I wrote above. No two of these cars are exactly alike and different fitment requirements may be apparent for any specific car.

This install was a breeze on the '89 GT. When I pulled the one out of my '88, I saw absolutely no difference in the mounting points, the fitment or any other issues

The only thing I would suggest is making the top end 1/8 of an inch shorter so that the fan shroud is able to to be a more tight fit at the rear end of the rad. This could be accomplished by making the top lip were the two fan shrowd 8mm bolts 1/8ths lower.

It actually doesn't make a huge difference, but from a fitment stand point, it looks more secure. Does not have the hand movement that one would expect.

Overall the fitment to the '89 GT was "good". It will work for a very long time, but the replacement or remachineing of the height of the top fan via the distance to bottom of the fan assembly needs to be about 1/8 of an inch to make it "perfect".

It works, it worked on mine before I had to pull it due to bad materials.

The fitment of the current 928 Int alum rad is great, I'd not hesitate to put another one in mine (except I don't have $800.00) And that is the only reason I dont have one in either of my cars now.

Take Rogers word on these. They look damn good, and the ease of installation if top knotch.

Spent Saturday working on my car and one of the projects was installing an alum C&R radiator that I bought from 928-International. I did the work over at Dave C's garage with him jumping in to advise and assist at critical junctures (as he's simultaneously doing a TB/h2o pump on his '91 GT) and his extra hands and experience were of tremendous help. Thanks Dave!

I bought the C&R after considering all options and reading the reviews in this thread. I wasn't put off at all by Carl's post which I thought sounded positive enough to begin with (not sure why some got their panties in a knot over that ) and in fact I was glad I knew exactly what the job entailed going into it which made it easier to prepare for and to do correctly. It was basically just as Carl, Dave C and some others said it was: beautifully made product, fairly simple installation that requires some minor tweaks. All the oil lines and water hoses lined up with original placements (although pushed slightly closer to the engine due to extra thickness of radiatior, but that was not a problem) and all replacement fittings were perfect. Only thing that keeps it from being a great fit in the end is the top overflow hose and plastic spigot being a bit too high due to the hose routing as noted above, which may put undo stress on the part over time. Other than that it now fits like a glove.

I would not consider this a drop-in 'plug-&-play' replacement though. It requires trimming metal off of the radiator in several places in order to get an optimum fit. I don't see this as a negative at all, its just the way it is with performance part made to fit all years and model of 928. In addition to cutting several metal tabs, I trimmed a small bit of the shroud to get it more snug, and cut about 3/8" or so off of the front of the rubber 'pucks' that the radiator sits on in the car. I may have been able to skip a few of these mods and still gotten the thing in and working, but I am certain that it fits my car much better after taking these extra steps. I know this because there were several test fittings of the radiator and shroud along the way at different stages of trimming before final installation and things did not align to my satisfaction until these modifications were done. I didn't want any extra gaps that would allow for movement or areas in contact that could cause premature wear. Mine definitely fits better than the one in the pic that I posted above.

It was a tight fit, but in the end it looks great, ran with no leaks the first time starting and seemed to run perfectly, although there was a snow storm so no test drive... The piece is so well made (the welds are artwork) that I see no reason not to expect many flawless miles from this radiator. Overall a high quality aftermarket performance part at a competitive price that I would recommend to anyone considering as a replacement.

Have to assume from Sean and Roger's posts that they meant there were no fitment/tweaking issues after trimming various tabs off of the radiator We compared Dave's fan shroud from his '91 GT to my '87 and they were identical, so the same steps would need to be taken to mount the C&R in that car.

Because without doing these various mods I'm not sure how you would get a good fit, unless it is true that everything is bigger in Texas, including 928 engine compartments

Does anyone know what the differences are between the (no longer available) later production Devek aluminum radiators and the current C&R/928 International units?

SeanR

Nope, we didn't do any metal trimming.

ROG100

No metal trimming required at all - perfect fit first time.
What tabs did you have to remove - there were no tabs to remove. Why would it have tabs on it if it was made to fit a 928.
Do you have pictures of the tabs you removed?

borland

Perfect fit; cut to suit, beat to fit, paint to match.

perrys4

No tab removal here either.

Bill51sdr

Mine did have some metal "tabs" on the side where the cooling fans mount up. I had to cut them off with a hacksaw (hey! I was in a dirt parking lot! ) in order for the fan pack to seat properly on the radiator. It is my belief that some older 928's need these. They are in the same spot that the "tabs" are on the plastic tanks that you can buy to repair the Behr radiators.

My Devek radiator failed just out of warranty because it was epoxied. I had read about such problems, and asked whether the one they were selling me was a newer brazed unit. They said yes it was, and when I looked at it that seemed to be the case. It was an optical illusion, as the epoxy was perfectly clear and looked like metal.

Funny thing, when it failed a month past warranty, I called up with the serial number and was told after Scott spent 30 seconds looking up the number that it had been epoxied! Sure enough, when I took it out and had a good look, epoxy separation was the issue.

Susan offered me a replacement at cost+10% which I declined.

I put in the C&R from 928I, which fit very nicely with somewhat less massaging than has been described in this thread. My only issue was with the vent hose, and I had my brother look into making a custom banjo fitting(~$25 in quantity IIRC) for that, but the idea fizzled from lack of interest here.

The C&R has been working great since then, no issues. I would heartily reccomend it to anyone in the market for a new rad.

I just cut a half inch off the bent hose and the clearancing issue pirt near went away.
