Then we turned the entire assembly by hand to make sure we weren’t going to crash the valves and all was well there. So we timed it the best we could without the marks. In the service manuals, it says there are marks on the timing belt that need to be lined up with the marks on the cam gears.īut there aren’t any marks on the timing belt. #2jz ge vvti timing belt install pdf#Went ahead and ordered a new timing belt from Lexus and went ahead with reinstalling it following the pdf service manuals. Supposedly, I heard the larger head gasket makes it a non interference engine. Timing belt broke and don’t know if the motor is gone or not. That is the one you want to ensure is lined up.īackground: Turboeast Stage 2 engine – I’m guessing that just means the 3mm head gasket to lower compression. The focus of this article will be the timing belt replacement on a 2001 Lexus GS 300 with the in-line six-cylinder 2JZ-GE engine with VVT-i (Toyota’s variable valve timing). The sub timing mark should be to the right of that one (60 degrees). I think your picture is showing the main timing mark. #2jz ge vvti timing belt install install#The sub timing mark should be 60 degrees clockwise (to the right) of the main timing mark and it (the sub timing mark) should be set on TDC (0 degrees) when you install the timing belt. However, are you focusing on the crank pulley sub-timing mark as well? The crank pulley has two marks as well. I am not sure if this may be the issue, I see you have your cam sprockets correctly on the sub timing marks. #2jz ge vvti timing belt install zip#(I advise using zip ties to keep things in place until the tensioner is released). Get everything back to position and re-install belt. If at any time if you feel harsh resistance, stop. When you find the sweet spot, slowly turn the cam sprockets back into position in a clockwise manner. Ensure that every step is done correctly, and the proper tools and procedures are used to prevent comebacks, driveability complaints or difficulties in completing this service.Don't worry about turning the crank backwards, the belt won't be hooked up (which you don't want to turn valvetrain backwards) and it will be for less than a whole turn. A quick scan through service bulletins, tech assistance requests and first-hand experience with this repair leads me to advise that extra care be taken on this repair. ![]() Due to the possibility of engine damage if the belt breaks or jumps time, I would not recommend waiting beyond six years or 90,000 miles, which is the OE-recommended interval for this engine. Cars that are driven primarily in hot, dry climates will probably benefit from earlier replacement than those living in more moderate conditions. My advice is to look closely at the accessory belts, note any cracking or evidence of replacement, and then factor in the use of the car and its maintenance history. #2jz ge vvti timing belt install manual#Depending on which tech manual or tech assistance site you access, you can get widely varying mileage and time suggestions. WHEN TO REPLACE Recommended replacement intervals for timing belts are all over the map these days. These seals are known to leak on higher mileage 2jz engines, so replace them while you're in there. I also recommend doing both cam seals and the crank seal too since you're already in there. The timing belt job is recommended every 90k miles by Toyota and should include the water pump, timing belt tensioner and tensioner pulley along with it. Getting this job right is extremely important because some forms of the 2JZ are interference engines so you can ruin the engine if you don't do it right. This process will be the same on all Toyota 2JZ engines, including 2JZGE and 2JZGTE both with VVTI and NON VVTI. #2jz ge vvti timing belt install how to#So in conclusion, I suggest ordering all of these: In this episode of Racecar And Chill, we go over a step by step instructional tutorial on how to do the timing belt service and replace the cam seals on a Lexus IS 300 along with taking out the harmonic balancer with the starter bump method. This tune up will ensure your IS300 or 2jz ge vvti car will last another 100k without any issues. ![]()
