Time chain tensior how to take tha time chain off

There are no diagrams of that that I know of //// oil is pumped into the engine and travels through the engine block to lubricate the cam and timing chain/s OHV OVERHEAD VALVES nto the valve lifters then up through the push rods into the cylinder heads to lubricate and cool the valve springs and the cam/s if Daul overhead cam THERE'S 2 AND 2 CHAINS THAT'S HOW THEY WORK WHAT IS THE PROBLEM IF ANY THAT YOUR HAVING?

There is a Toyota Technical Service Bulletin issued for this:-

Set the No. 1 cylinder to TDC/compression. A. Set the timing mark to 0 on the timing chain cover by rotating the crankshaft clockwise. B. Verify the timing marks on the camshaft timing gears are in general alignment with the timing marks of the camshaft bearing cap: TIMING MARK IDENTIFICATION CYLINDER BANK INTAKE GEAR MARK EXHAUST GEAR MARK RH Bank (Bank 1) Small Mark Single Line LH Bank (Bank 2) Large Mark Double Line HINT When the engine is correctly timed, the timing marks will NOT perfectly align.

Component Removal Guidelines 1. If engine disassembly is required that involves removing the camshafts or timing gears, set the #1 cylinder to TDC compression, wipe away any oil, and mark the following items in relation to each other prior to disassembly: • Timing gears • Timing chain • Timing chain No. 2 NOTE This relationship MUST be maintained. The intake gear is timed in relation to the crankshaft via the timing chain; the exhaust gear is timed in relation to the intake gear via the No. 2 timing chain. © 2008 Toyota Motor Sales, USA T-SB-0291-08 September 11, 2008 Page 5 of 5 2GR-FE Valve Timing Procedure Component Removal Guidelines (Continued) 2. If NEW camshaft timing gears or the No. 2 timing chain are being installed, the two yellow links on the No. 2 timing chain can be used to ensure correct relationship between the intake timing gear and the exhaust timing gear. Figure 7. 1 1 Yellow Link A. Align the paint mark on the timing chain with the intake gear timing mark (to ensure the intake gear is correctly timed to the crankshaft). Figure 8.

best thing u can do is get a haynes manual for tha vehicle, but what i would do, is take tha timing cover off, visually inspect the chain and sprockets, and if they have no wear, just change the tensioner.

look for a square cut out on the tensior u can use a 1/2" ratchet too relieve the tension

use a 3/8 drive ratchett and Rotate the drive belt tensioner clockwise in order to release the spring tension. there is a square hole that a rachett will fit into the tensior

it takes out the slack and prevent your timing from slipping .if you dont have a tensiore your car wont start because your timing would be off

the V6 uses a timing belt, what idiot told u it was a chain? a salesman?

you will probably find that a timing chain is in the engine for the life of the engine or until it needs to be replaced,

You may want to see what it says in the owners manual about the 4%. As far as the " coolant" you want to use "DEXCOOL" antifreeze, follow the directions on the antifreeze container for proper mixing.
