im currently doing my swap into an s13 and was wondering what you guys have used to connect the heater hoses together. I read an article that suggested 5/8 to 3/4 in hose adapters, but i havent been able to find these.. anyone have any suggestions?

 

i forgot what i used, but it was some little metal pipe i got from the ka... basicalyl anything that will fit inside the 2 lines..and be sure to tighten these... heater hose leaks are ghey when your motor is all in and situated...

 

are the two hoses the same diameter? or is one bigger than the other?

 

look at them and you tell us.

 

lol, dood just get a freaking piece of little pipe from the homedepot plumbing section that will fit inside the heat hose... buy some hose clamps and insert them and tighten down?? what is so complicated about that?? all that matter is that coolant gets where it needs to be and it doesnt leak... simple as that

and yes they are the same diamter

 

I'll tell ya what...where are you located? If you are close enough I will make you one out of stainless steel for lets say/........ $200...sound good to you ?
