I need to buy a replacement radiator; the bottom hose connection cracked today.

I want something that is a direct replacement for the OEM utilising the original fans; same dimensions, connections and fitting points.

Radtec do one, but as I read their website it won't accept the original fans. Is that right?

What is the view on Airtec?

Any other suggestions?

Thanks

 

I have the airtec rad in mine and i have no trouble with it and cheaper than buying one from Ford

 

I think i would have bought this one.

Is it a straight fit replacement?

 

ive got one of them ready to fit to my car and its supposed to be a straight fit but i think jw racing iirc does it a little cheaper on delivery

 

I have the 70mm version of the one shown, mine is also airtec, fits perfect no problem at all.
When I then fitted the 70mm airtec i/cooler I was annoyed as there is no fitting type bit between the rad and i/cooler, which would have been very helpful, the rad would secure on to the base of the original ford i/cooler however, but on it's own a loose fitting, ie it tilts with the engine movement, hardly any but a bit, all I did was cut up a few bits of rubber put between rad/i cooler where they touch at top on edge, then tie wrapped around the top inlet of the rad and around the headlight rear bracket area, don't even notice it in use, I even used a nice green tie wrap!!
btw they are bloody heavy but well made, seem very robust, not the beates welding in the world, but perfectly strong which I find more important, they fucntion perfectly, defo helps to have 2 people when fitting the i/cooler due to weight.
I've done many many rr runs and they work excellently, my iat were averaging around 34C.

Pro alloy gets my vote bruv good products, good craftsmanship and spot on customer service

i got 163kg whit airtec products, last summer (not only for me), free delivering to Norway.
Product is straight fit, only down thing is a bit heavy coolers. Black pro series looks more original. I use 62mm ic and a turbo cooler from them on my escos.

Thanks for the replies.

I want black; to retain the original look. Although the weight issue worries me.

 

They are heavy, just goes to show the thickness alloy used, so should be very strong and last, the weight is not anything that will be aproblem, don't know how it compares to others as did not measure the weight, I wouldn't hesitate to use again.
I don't expect you will see a huge saving in weight using other ones, the airtec are the best for performance/Ł.

Is the 3 door radiator exactly the same as the Sapphire unit?

There is one manufactured in Australia by PWR. They have sent me the attached drawing but they don't seem to know if fits both 3 doors and the Sapphire. Can someone look at the drawing and tell me whether it is right for a 2WD Sapphire?

Thanks

 

There is something wrong here. The temp sender should be located down on the left side, and it seems like the upper left ear mounting to the IC should be placed more like the right one. At least the mounting holes for the fans seems to be correct.

 

The drawing should be rotated 90 degrees to the left; it just came out that way when I posted.

Making that allowance, the sender collar is on the bottom left.

 

Here is the drawing in the correct orientation.

 

With the drawing that way the water inlet/outlet and fan switch hole are in the right place but the ears for the connection to std i/cooler are on the bottome when should be on top, and the top should be at the bottom.
If using a 500 type i/cooler no need to worry about the ears as they won't be attached to anything.
I fully suspect it is just a drawing cock up and they are in fact correct the way they're made.
Having just phoned Rod at auto specialists for you, they are the exact same one they(airtec) use for the 3 door and sapph, they only make the one style of 500 i/cooler.
On some 3 doors I have found a 3/4"-1" variation on distance apart from chassis rails, don't ask me why, as have no idea, none of the cars had any accident damage either.
I've never known a problem with airtec fitting 3 door or sapphy though.

where's my piccies of REBECCA GIBNEY ?
tabetha

 

I am looking for you.

In the meantime; do the Airtec radiators take the OEM fans or it it necessary to change them as well.

 

I'll tell you when I get my piccies!!
No the std fans fit fine no problem, might be a good time to replace the rot prone pipe that runs across the rear bottom of the rad, I just used SS pipe with juby clips, then 2 tie wraps to hold it near the other pipes but enough slack to allow a little movement, been fine, couldn't be bothered to weld any brackets on!!

this company next to me lists one for the cosworth,standard replacement not uprated.

http://www.adrad.co.uk/car-radiator/...D&model=SIERRA COSWORTH&year=1989

 

Thanks guys.

I will point out to them the issues with their drawing and see what they. That said I am going to order an Airtec and possibly the slim line fan kit as well. I assume the Airtec fans plug straight into the existing loom (although may car now has a CarLooms UK thermo fan loom)

BJAS,
There's plenty enough room on the sapphy with the std fans there, I manage to get a socket on the crank nut and then the ratchet, bit of a struggle but does go, so they are not needed, but up to you if you want to change, the kenlowe curved vane one is awsome output versus power consumption.

Sorry to semi hijack this thread, but is anyone running a 50 MM airtec rad, do they find it provides enough cooling, as I'm running one of these in a custom v8 installation, and running very close to temp limits. (I'm running about 230 BHP)
I was wondering if the Rad was up to the Job, or do I have other problems.

I was concerned about the design with the large water ways. as the Pro Alloy ones and radtec Radiators use lots of smaller water ways.

So was wondering how the compare.

Thanks
Leigh

 

give SPEC R a ring he is doing new style rad and intercoolers. his number is 01380 724518 or see him at ford fair. spec r have developed a new 50 mm core rad that is being used on rod tarry,s 850bhp car and works very well indeed.

 

I really want to hear from anyone else running the 50mm airtec radiator, as trying to work out if my problems are due to the radiator or the engine.

 

Hi

Just to let you know the Radtec rad is a direct replacment for a OE rad and the OE fans fit no problem.

Also some customers request the fan switch outlet to be moved to the top right of the rad as it will make the fans come on quicker than if it is fitted at the bottom.



Interesting

 

I went down the Airtec route. Super value for money Ł200 delivered and it's a direct bolt on replacement, everything fit perfect.

I can get you a couple of pics if you need them, it's off the car with fans attached

You could paint it ?

Also available from Ford still Ł280. They come with different colour end caps....

 

Be interested to see how your temperatures compare before and after

 

v8 leigh - What fan switch are you using ? Any part numbers on it ? Some of the switches do not turn the fans on until well over 100 degrees C, which may be your problem

 

It's exactly the same mate, just the alloy one is a bit lighter.

It's a standard 50mm as well. Runs bang on in between O and R on NORM gauge. Fans come on just above the O and it cools down in around 1-2 minutes

The only mod I had to do was replace the original metal clips and screws to attach the fans to the radiator with 4 short nuts n' bolts.

 

My fans are controlled by the ECU, so come on at 85oC and 90oC

Also due to it being installed in a racer car, it always got air flow. so should not as such need fans.

Going to have a Experiment with water wetter, and do a pressure text.
Problem is it's not easy to test as I can't use it on the road.

 

Anybody knows where i can find new radiator hoses for the standard 16 ohc sapphire ?

 

i ve got a 50mm airtech in mine and have no troble with it at all, running stg1 about 280bhp
with the standed fans rewired and a cooler fan swith
