MrFairlady · 02-19-2012, 01:33 PM

Need some help.
No Heat after trying Multiple diff Things.

Posted in 2-3 diff areas of the forum and Searched Everywhere, and No one shows how to Route S14 heater hoses with a Red/Blk top Sr20. Only S13's and a friend has a S14 Sr20's in his S14 that are routed diff since the manifold is Diff.

Which hose to heater Core Goes where?
I routed mine Similar to my S13 with the same engine but for some reason I had heat at 1 point and It now Does not work.
Car also wouldn't quite get to normal Operating Temp (61degrees Cel) so My car is over-cooling or I thought the Thermo was staying Open, untill I changed Thermostats yesterday, back to OEM and re-bled system 2-3 times before that & again. Finally its running at 81degree's Cel with cardboard in front of rad/condenser area also.

help.

rear heater hoses not getting hot (Update: they get hot now**) and Don't seem to hold pressure like the Front rad hoses do.
-Checked heater valve
-Swapped from Nismo Thermo to OEM
-Checked Fuses and all servo Motors
-Stock Clutch fan and Shroud
