I had my timing belt changed yesterday.
also, ac belt, alt belt, couple seals, couple gasket, bearing set, timing tensr, water pump, oem coolant, spark plugs and tranny fluid.

after i got back my car, everything ran great and fine EXCEPT:
I have two fans behind the radiator, one use to be one all the time and the other just kick in and shut off after a while for cooling purpose. Now, my coolant level is on the mark "high", after about 5miles driving, the second fan turned on and suck in air etc. but.....i stand next to my car for about 5 mins, the second fan still on( they use to be off after 1-2mins in the past)......engine looks cool and nothing weird. but the second fan doesn't go off, and the coolant still stay at high level.

is my engine not hot enough to run the coolant into the engine?

is this sounds normal?

I might want to try to test run for a longer trip and see if this still happen.

any input are welcome.

what does your temp guage do?

Do you have a Check Engine Light on?

Try burping your radiator, you could have an air bubble in your coolant system.

Get an OBD reader as well and check to see if there are any stored codes in there

i think the thermostat is not working properly.
the coolant is not sucking into the engine.

thermostat i say, i replaced mine a month ago, it's real easy, u can test it just in case you don't want to buy the 25 dollar part, take off the thermostat after draining the coolant, then drop it in boiling water and see if spring works
