neill1607 1 1 Vehicles Report post Posted December 27, 2013 Whilst the radiator's being re-cored & all the shrouds (broken in several places) are off, I thought I might as well replace the original fans with the slim Kenlow units & do away with the shroud. Has anybody done this? Got any photo's of the installation? I thought I remembered reading a post a couple of years back to do with the fitting kits wearing through the fins, but can't find it anywhere! Thanks Quote Hooligan at heart.

mdw 231 Report post Posted December 27, 2013 Yep and all works fine sofar............. 500miles. However I probabaly will drop the rad pack at a later date and fit the stainless rad mount frame and bolt the fans to that via brackets rather than directly through the rad fins as they are at the moment. I got mine from Car Builder Solutions in Staplehurst Kent. Quote Share this post Link to post Share on other sites
sailorbob 247 Report post Posted December 27, 2013 I had my fans fitted with the through fin fitting kit and I have changed them as they were rubbing excessively. It did not get to the point where they broke through any tubes but given time it would have happened. Quote Share this post Link to post Share on other sites
Buddsy 1,494 1 Vehicles Report post Posted December 27, 2013 I used the fans by Tripack. I fitted them to the existing shroud and seem to work well. Buddsy Quote "Belief is the enemy of knowing" - Crrow777 Share this post Link to post Share on other sites
neill1607 1 1 Vehicles Report post Posted December 28, 2013 There's a range of different sizes (7" - 16") available on the car builders site, & I don't have the radiator to check sizes at the moment. Anyone recall what size they used? Quote Hooligan at heart. Share this post Link to post Share on other sites
Buddsy 1,494 1 Vehicles Report post Posted December 28, 2013 I used 11". I used the dremmel and a belt facer to grind off the mounts then pop riveted them into the old shroud. Thats what I done. I didnt like the idea of the direct mounting to the rad. Can be ok but must be tight or vibration can make them work loose and break your rad, Buddsy Quote "Belief is the enemy of knowing" - Crrow777 Share this post Link to post Share on other sites
mdw 231 Report post Posted December 28, 2013 (edited) I am pretty sure mine are 2x 11" with a 10" in the middle. or at a very outside it could be 12,11,12. Depends where they measure from. I took the rad down there as they are nearby but it was 18 months ago. What ever it was there is not a lot of rad that's not covered.

gtookey 80 1 Vehicles Report post Posted December 28, 2013 After wrestling with my S1 radiator and fans the last few days, I sometimes envy you guys with the later cars. That rad and fan setup is sooooo much better. Quote Cheers, Gavin Share this post Link to post Share on other sites

Roy Lewington 36 Report post Posted January 2, 2014 Hi Niell As I understand it the shroud is an important part of getting the maximum airflow through the rad, as are the foam strips top and bottom. The shroud should be quite an easy repair (alloy strips and pop-rivets -or fibreglass).Why would you have a nice recored rad and then bolt fitting kits through it, asking for trouble.Cheers Roy.

mieczkow 0 1 Vehicles Report post Posted February 8, 2014 (edited) The shroud is made of ABS plastic, and repairing it with fiberglass resin can be very tricky. Cracks should be repaired with an ABS solvent/filler mixture (a smelly ketone solvent and some ABS powder). You can use cloth or mat to make repairs using the ABS material just as you would with fiberglass, but the ABS solvent truly bonds with the plastic while fiberglass will often fail to bond, Some have used the old shroud as a plug and fabricated a true fiberglass shroud. Also it is popular to make a shroud from aluminum, which will work very well. Edited February 8, 2014 by Tom Mieczkowski Quote Share this post Link to post Share on other sites
top-plumber 521 Report post Posted August 3, 2014 Has anyone noticed that since they upgraded their fans that the AC works ok but after a time the fan fail light comes on. It goes out after a short delay when AC is switched off but didn't happen with my old fans. Wondered if the motors overheat when running continuously with the AC. Got to admit I didn't buy the most expensive fans but non the less. Puzzled ! With AC off works as normal with water temp switch.

MrDangerUS 97 1 Vehicles Report post Posted August 7, 2014 (edited) All fans are made in China, except SPAL fans (so I’ve been told).

If all the fans start at once (which mine should, apart from the fact that two are knackered), I'm wondering if the original wiring to and from the relay (there's only one on the S4s) will cope?

dodge1979 36 Report post Posted August 20, 2014 My s4 wiring copes perfectly with the upgraded fans...get a decent set of fans and youll be fine. Quote Share this post Link to post Share on other sites
MrDangerUS 97 1 Vehicles Report post Posted August 21, 2014 To clarify my previous statement: The 'pancake" fans I used initially were not SPAL-s. Spal fans of the similar shape and thickness would probably suffice. Whatever you'll decide to buy, always look for a "sealed motor" in the specs sheet. I'm not familiar with S4 wiring. Perhaps it has been upgraded. Older models had some marginal wiring and a single 2x15A (!) fan relay. FYI, the in-rush current could create 20-23A spike per fan on start-up. To be on the safe side, I have installed two additional high power relays (60/40A BEULER relays), which are triggered by OE 2x15A relay. Quote Share this post Link to post Share on other sites
