after changing timing belt, finally everything is in and I'm running the car for 20 mins now, but the radiator doesn't want to come on. Its cable is still plugged in, heater is at max level, dont know what's wrong , please help guys

 

take the car for a spirited drive to get the engine hot and then see if the fans come on.

could be

1. bad relay
2. bad temp sensor
3. bad fan motor
4. t-stat stuck open

 

Did you also change the W/P?
Fill and burp the coolant system?
What is the Temp guage level?

 

Ditto from above. These guys stated everything I would. If you replaced the H2O pump then you might indeed have air in the system and need to bleed it out. That is the most likely culprit. Good Luck.

 

wheres the temp level at. if youre temps is around the center when warmed up, then you should be fine.

my ac fan kicks in when ac is on. my "other fan" used to kick in after i shut off my engine after a ride, but after replacing my thermostat, "other fan" does not kick in anymore. engine temp on cluster is around middle so no prob.

 

all of my hondas and my acura never go above 1/3........i would start getting concerned if it was 1/2 way up unless it was an extremely hot day.......

 

I did bleed the coolant like in the helm manual: fill coolant until no more bubble come out then TIGHTEN THE BOLT before turn on the engine. Would that be the cause? I drove the car to work today and temp gauge still read normal, almost halfway, same thing as before

 

turn your A/C on.......the fans (both) should com on immediately

 

when i turned ac on, both fans didn't come on either

 

Does the compressor cycle on when you put the a/c on? If not, you have an a/c problem.
Check your fan fuses and relays.
