DIY Replacing radiator hose
So I was installing new engine belts and had everything finished up and while I was putting the radiator fan back in, I sheared one of the small radiator hoses
![]() ================================================== ================================================== ========= Ok, got this done - wasn't too bad. I ended up only using #4 (11537838214) and #1 (17122283591). For the hose clamps (#2), you would really only need 1 because the vent pipe already comes with one on there, however I would highly suggest using a worm clamp instead so you can unplug the vent pipe to be able to remove your radiator fan more easily in the future if needed. In the first picture, you can see the tip that broke off. It didn't take much force honestly, just too much heat made it brittle over time I guess. In the second picture, you can't really see too well, but the tip is stuck in the hose. In the third picture you can see all 3 connections boxed in yellow. So you have the nipple that connects to the vent pipe, one side of the main hose connecting to the radiator (pic 4), and one side of the main hose connecting to the block/thermostat (pic 5). For the 2 connections of the main hose, there's just a simple clip that holds the hose on by blocking the flange from being removed. You can see the clip by itself and on the hose in the closed position in pictures 6 and 7. To remove this clip, just get a screwdriver and pry it up by the top/middle, it will come off quite easily. Then all you need to do is pull the hose off the flange. Pro tip: have a bunch of rags/shop towels ready, because when you pull the hose off the block/thermostat side, a lot of coolant will start to gush out. I stuffed a heavy duty rag in the hole to try and stop the flow as much as possible. The fitment is pretty tight, so it can be tricky pulling it off - ESPECIALLY on the radiator side. Because the flange that sticks out on the radiator is plastic and seems like it wouldn't be too hard to break off. Unfortunately, I don't have a surefire method of getting it off. All I can tell you is that I used a screwdriver between the hose and the flange connection to gently pry/loosen the hose. After that I ended up cutting the majority of the hose off so I could get a better grip with a pair of pliers. It took about 15 minutes of carefully twisting it (not too much!!) and pulling as perfectly horizontally as possible to finally get it off...and I still slammed my hand full force into the engine when it finally broke free ![]() There is another one of those clips holding the vent pipe to the expansion tank (pic 8), but the clip and vent pipe should detach with no drama. The new hoses come with clips already, so you don't need to reuse your old ones. Just take the new clips off and slide each end over its respective flange. Then, you can see in picture 9, I attached the vent pipe to the nipple coming off the main hose and then added the worm clamp shown in picture 10. Lastly, you need to refill your expansion tank to make up for the fluid that inevitably came out. - Last edited by M3MPH1S; 05-19-2017 at 01:03 AM. |

Whoops, should have done more searching first. Just stressed out...
From the ECS picture it looks like it comes with part #1 https://www.ecstuning.com/b-genuine-...e/17122283591/ However since I've got the thread going...are there any other parts I will need to replace this hose? |
