Coolant hose clarification

[craiggroves91]

I'm almost finished up with my s52 swap in my 318is and I'm trying to get a list together with hopefully all of the last parts I need.

I'm having trouble finding info about coolant hoses, I have searched without much luck. Please clarify this list for me
The radiator I'm using is the e36 m3 mishimoto Radiator
Not running throttle body coolant lines
Radiator hoses: Top- Stock e36 m3 hose ?
Bottom- E34 m50 hose?
Heater core hoses:
Back of head to bottom heater core line- ?
Back of spider hose to top heater core line-?
Coolant reservoir to Spider hose- ?

Thanks
-Craig

The "spider" hose connects to the top heater core pipe and the coolant hose from the back of the head connects to the bottom heater core pipe.
Just remove the heater core like i did.

Yeah I got that, but I need to know what hoses to use.
I need a heater haha

got them figured out!
Used all s52 e36 m3 hoses.
The long hose from the m3 that goes from the metal pipe to idk where, made my heater core hoses and coolant reservoir to metal pipe hose.
Just needed to do a lot of cutting.

Does this apply for a stock late model e30 radiator as well? (I would think yes, but just want to double check, because I thought both e36 hoses worked)

Both e36 hoses worked for me
My e36 m3 mishimoto is the same as a late model e30 radiator.


Might have to trim the bottom one a bit more

go to NAPA and buy 2 hoses part # 8484. straight with right angle about $21.00 ea. cut to fit..works on top and bottom. slips right on ( at least for my M50) / 89 I stk radiator) cleaner than the E36 ones IMHO
and yes I bought the e36 hoses but thought they looked like crap. they're in a box someplace.. GL
