So sine I crashed (and ruined my Si radiator).... I put int a new radiator (a DX radiator) and after millions of times trying to fix it, I finally gave up it had too many leaks. So I pulled my radiator off my HF but realize not only is it plastic but has smaller flanges. So I tried to use the HF radiator hoses but they wouldn't fit over the B-series bung/flange on the engine. So then I tried the Si hoses but I had to tighten them down really hard on the HF radiator bung/flange. Now I'm still having leak issues and I realy dont want to tighten it more because I'm afraid of cracking the flange. Any suggestions?

 

If the hose is too big then use a short piece of slightly smaller hose between the existing hose and the flange. Basically it's just a rubber bushing to fit the large hose to the small flange. It's kinda ghetto but it works well.

 

ive seen the radiator hoses where one end is larger then the other. maybe u can go behind the counter of your local autoparts store and fish one out

 

.......go by an SI radiator? Money is money man I know were all in need of it, but if that is the case yoru better off not to drive the car and save your cash then keep trying to rig it up and possibly ruin the most important part of the car, your engine.
