i need to know if anyone can tell me exactly which hoses are the heater hoses on an rb25det. i have this in a 95 240sx. problem is it is soo close to the firewall i cant see them. i know its gonna be behind the engine against the firewall. also will i need a fitting to reduce or increase the hose to the firewall when i connect them. the car didnt have heater hoses at all so ill need to start from scratch.

 

if it didnt have heater hoses at all, they must have been capped off somewhere, and I would just match those to the ones coming off of the intake on the RB25. the one that comes off of the motor on or around the waterneck is the end and the other is the return. (dont take what I say as law, I am just doing my best to remember without a car in from of me) as far as I know I have never had to adapt the size of the hose so I guess they are the same.

 

thank you very much. ill take a look at it this weekend.

 

its fixed temporarily. i got heater hoses on it. just waiting for the valve to shut it on and off. they both come out the passenger side rear of engine.
