Squeking belts i just recently had the fan belt and timing belt replace on my 2003 honda accor, now when i first start the care and at idle & low speads the belt(not sure which one) is sqeaking, do they need to be tightened & if so how do i do it?

Possible water pump. Remove the belt and grab the pulley , wiggle and spin. Check the other pulleys as well.

readjust the fan belt and check the condition of the pulleys The secondary air injector is showing a malfunction ---causes are ---wiring---AIR valve--- AIR sensor--- ECMI would be checking the wiring and connections as they may not have been replaced properly after the timing belt work. Replace with genuine units only as some after mark units are not compatible with the cpu.

Whats the rpm at? Could have a number of issues, Idling, timing belt, low coolant, low oil etc..

timing is off

both fans do not turn on at the same time. one fan is for the AC condensor and the other is for the radiator. A/C turns on one fan, Radiator temp switch turns on the other one. If you have never replaced the thermostat, or done a radiator flush/refill, you should do one now.

First things first. The check engine light is blinking because the engine is misfiring to a point that could damage the catalytic converter. If cylinder 4 5 & 6 are all misfiring i would check the engine timing belt for proper installation. These are the cylinders for the left bank of the engine. If the belt has jumped or was installed wrong this would explain the misfires. Unfortunately this is an interference motor which means there is a high probability if the belt is on wrong, the engine valves mat be damaged. I would perform a compression test on those cylinders to verify the belt condition. Hope this helps.

could be cv booth starting to worn out

you should be good thats normal to replace drive belt around 100k

Replace the alternator.

Don't know what a radiator timing belt is? What you probably mean is timing belt and water pump. In honda's the water pump is inside the timing cover, I recently checked on this low end was about $750.00, high end at most dealers is about $1200.00. I did mine myself for $51.00 and a days worth of labor.
