Flash69 10 Report post Posted September 16, 2019 I'm making some changes to 1969 Coupe. First I'm replacing a leaking radiator with a 24" aluminum radiator. Thank you to all the reviews on this site. While doing this I found all kinds of scale in the cooling system so I have gone a little more down the rabbit hole then I likely should have. While cleaning things I have decided to change the water neck to a 90 degree unit as one day I plan to install AC in this car. I can't seem to locate the correct Upper radiator hose that will support the 90 degree neck on the intake manifold. I'm hoping someone can point me to the correct hose. I ordered a hose I thought would work however it's the same one I already have. Quote Share this post Link to post Share on other sites
Mike65 475 Report post Posted September 16, 2019 If your upper hose location is still on the passengers side IIRC you can use a upper hose from a Fox body Mustang like a 1987 w/the 5.0 as they had the 90° water neck. https://www.rockauto.com/en/moreinfo.php?pk=2556&cc=1133895&jsn=586 Quote Share this post Link to post Share on other sites
barnett468 418 Report post Posted September 16, 2019 there is no need to run a different water neck with ac. Quote Share this post Link to post Share on other sites

Flash69 10 Report post Posted September 17, 2019 Thanks everyone so far. Yes, the upper hose is on the passenger side. I could possibly use the newer hose as suggested. I have seen several Mustangs with an upper hose that went into the 90 water neck which didn't use the newer hose suggest above. I guess I thought there was a correct hose from 69 or so Mustang that I just could not locate. Quote Share this post Link to post Share on other sites
1969_Mach1 333 Report post Posted September 17, 2019 I don't understand why you need a 90 degree thermostat housing? Like Barnett468 mentioned, there is no need for that with A/C. Quote Share this post Link to post Share on other sites
