96 Acura 3.2 overheats after replacing the top radiator hose.
There is a curve in the hose. Why, and does it matter what position it is installed in? I have a 1996 Acura TL, 2.5L. We replaced the radiator and now the fans won't work. We checked all the fuses that we know of. What can it be that is making them not work? How do we check the relays?

Radiators fail, why, well it may have a factory defect from day one, had a few of those. As far as filling goes remove the upper radiator hose, remove the thermostat and the fill through that, that should purge most of the air, reinstall the thermostat and hose, continue filling with the front of the car in the air on jack stands this lets any trapped air migrate to the top, also look for any small fitting that kind of look like grease fittings these are bled ports fill with those open, Fill the recovery to at least 3/4 full ad run engine but do not overheat, turn off the engine and let it cool down. then check levels again and add as needed.
NOTE: Refer to following illustrations. Drain the cooling system by removing the radiator cap (8100) and attaching a 9.5 mm (3/8 inch) inside diameter hose to the draincock nipple, located at the lower rear corner of the radiator tank. Then, open the radiator draincock (8115) and allow the coolant to flow through the hose into a suitable container.
Loosen hose clamps at throttle body and engine air cleaner assembly. Remove air cleaner outlet tube and position aside.
Remove radiator overflow hose from the radiator, disconnect two hose locators at top of radiator and position hose aside.
Remove two fans shroud bolts. Lift the fan shroud out of the lower retaining clips and position it on the fan blade.
Position upper and lower radiator hose clamps, remove hose from radiator and position it on the fan blade.
Disconnect the two transmission cooling lines from the oil cooler fittings on the radiator, install protective caps over lines and position aside.
Remove two upper radiator bolts.
Tilt the radiator back (rearward) approximately 25 mm (one inch) and lift directly upward, clear of the radiator support bracket and the fan blade.
Position the radiator into engine compartments, make sure that mountings on both tanks are inserted into radiator support brackets. Install radiator retaining bolts. Tighten to 6-8 - (54-70 lb-in).
Remove protective caps from cooler lines. Connect the two transmission cooling lines at the oil cooler fittings on radiator. Tighten to 16-24 - (12-17 lb-ft).
Install upper radiator hose and position hose clamp. Tighten to 3 - (26 lb-in).
Install lower radiator hose and position hose clamp. Tighten to 3 - (26 lb-in).
Position fan shroud in lower retaining clips and install upper bolts. Torque to 6-8 - (54-70 lb-in).
Position radiator overflow hose, connect to radiator and locators.
Position air cleaner outlet tube to throttle body and air cleaner assembly. Tighten to 2-3 - (18-27 lb-in).
Fill the cooling system; refer to Cooling System Draining, Filling and Bleeding in this section.
Have you tried a thermostat?I would go there first for any overheat situation.It is the cheapest and probably more than half the time,it's the cause.Also,air pockets in the radiator system are not really a problem.It works itself out relatively quick.If your radiator is topped off,always fill your external plastic tank,usually located on the sidewall,to the cold full line.Good luck Liz!

have you changed the thermostat? located at upper hose opposite radiator end in the gooseneck (usually 2 screws) make sure you buy a gasket or gasket making compound if changing. most overheats occur due to stuck thermostat (doesn't open to cool) you could pull tstat out for temp fix but it wouldn't heat well in colder weather
Make sure that there is no air in your block. If it over heated then I would replace the thermostat. There should be a bleeder valve by the thermostat housing. you need to turn it Intel all the air is out and you get a good stream of water.I don't know how hot it got so if it got really hot then you need to make sure you did not blow a head gasket.
