Quick and easy way to replace drive belt in Celica GTS 2000- 2005 2ZZ engine with A/C
Belt should be inspected every year or 10K miles, and replaced about 50K miles.
Material:
(TOYOTA P/N TOY99366J1940 retailed $90),
or after market Good Year makes the old Gator Back belt with grooves, supposedly grips better and low noise, now branded and sold in eBay: GOOD YEAR Continental Elite 4060764 Poly-V / Serpentine Belt $26 reviews 4.7 out of 5
Tools: Tensioner tool loaned by Autozone, 19 mm shallow hex head, or combined vice grip and extension tube
There is only 1 belt that drives all accessories off the main engine crank shaft. If the drive belt breaks while you are driving, you will lose power steering and coolant pump, not to mention the A/C and alternator. If you continue driving, the engine will overheat within 5 to 10 minutes, potentially cracked or seized up, not the chance you want to take. You should pull over and stop the engine immediately.
The drive belt is scheduled replacement at 60K miles per factory recommendations. Check the belt regularly every oil change. If there are more than 10 cracks per inch on the grooved surface, it should be replaced.
There is no tension adjustment on this belt. The belt fits tight over the pulleys and kept in tension by a strut tensioner bolted onto the engine block on the passenger side. You are supposed to release the tension on the belt by turning the 19 mm aluminum hex head near the tensioner strut clockwise, downward. Autozone loans out a 3/8 inch tensioner tool to be used with a shallow 19 mm hex. Very easy to release the tensioner with this tool.
In case the 19 mm hex head has been damaged and cannot be used, instead use a vice grip on the hex head or wedge a big allen wrench lever between the hex head and the round base of the mounting bolt. Add a 12-inch steel tube extension for leverage to release the tensioner. It may be wise to tape the allen wrench in place.
Need 2 persons to do this procedure
1. Leave car on the ground. You dont need to get under the car. Remove the plastic baffle over the engine on passenger side. This is the only part that needs to be removed for this procedure.
2. Remove the old belt, if not broken, by releasing the tensioner while removing the loose belt from the alternator's pulley.
3. Check and clean debris and oil/grease off pulleys.
4. Start routing the new belt from the large crank pulley in the back of engine. Pull all loose belt forward toward front of the engine. This is the best way to keep the loose belt in place while routing it over the other pulleys.
5. From the bottom Thread the belt over all pulley from the bottom pulley toward the front, leave the top part of the belt loose near the alternator's pulley, in the sequence in the picture below.
6. When you get to the alternator's pulley at top front of engine, hold the belt next to that pulley while having the other guy release the tensioner with the tool, giving the belt enough slack to get over and into the alternator's pulley.
7. Crank the engine in a short burst and have the other guy check to make sure belt fits properly over all pulleys. Crank a couple short bursts to check fit. If engine runs without any unusual noise, then you are OK.
If done properly it's a pretty easy and quick procedure, in about 10 to 15 minutes with experience. The belt should be inspected regularly and replaced every 50K miles to make sure you wont have a broken belt and overheat the engine while driving.
