What Happens When Timing Belt BreaksĪs you can imagine, if the timing belt or chain breaks, your engine’s components won’t be in sync, and it’s likely your engine won’t start at all. But there are advantages and disadvantages to each of them, which we will explain later. Also, both the timing belt and chain work in the same way. The timing belt or chain has to be set up correctly when the engine was first assembled, so these components will work together smoothly. Here’s an animation of how the system works: The engine knows when to do this thanks to the timing belt/chain. Then when the engine starts the intake stroke, the camshaft will close the exhaust valve and opens the intake valve. For example, when the piston in cylinder one is in the exhaust stroke, the camshaft will open the exhaust valve, allowing exhaust gases to escape. The timing belt/chain connects the crankshaft to the camshaft to ensure that the camshaft opens or closes the correct valves and at the correct time. Moreover, the engine has two types of valves: intake valves that allow fuel and air to enter, and exhaust valves that allow exhaust gases to escape the engine. Meanwhile, the camshaft is a rotating device with metal lobes that operates the engine’s valves. The crankshaft is a series of cranks that moves up and down according to the engine’s piston’s movement. If you’re not familiar with cars, we’ll explain briefly how the timing belt or chain works: Specifically, between the crankshaft and camshaft. As the name suggests, the timing belt/chain is a belt/chain that synchronizes the timing for the engine’s moving parts. The Toyota timing belt or chain works just like in any other car. Final Conclusion How Does A Timing Chain Or Belt Work.Regular Servicing & Maintenance Schedule. ![]() Which Toyota Model Has A Timing Chain Or Belt?.The latter also goes into the proper servicing for a belt or chain, and the replacement cost. Aside from that, we’ll even look into how you can replace one DIY. As well as, the symptoms that you might notice if the timing belt or chain is on its way out. Our guide here will also look at the causes of why a timing belt or chain wears out and fails eventually. We’ll list down what your Toyota vehicle has in its engine, and how to maintain them. But which does your Toyota use? What are the differences? Does your Toyota use a timing belt or chain? In this post, we’ll discuss the timing belt and timing chain. Sorry, just have to vent a bit here.All cars with an internal combustion engine have either a timing belt or timing chain, and that includes Toyotas. But this truck has been nothing but problems in just a few months. Man! I was willing to pay more to buy a Tacoma for its reputation of high quality. But it seems to me that I can just unbolt the four bolts holding that green circled cover, applying some RTV. I want to confirm with the experts here is this the timing cover leak?Īlso, I have found that the repair is extremely labor intensive and costs thousands of dollars. So there is no doubt that it has nothing to do with power steering. It seems to be surrounding that square rusty cover right below the hose circled in green (is this the timing cover)?Īfter 1 weeks of in town driving, I clearly see oil seeping out to the bolt pointed by the arrow. I was hoping it was the power steering fluid spilling over, so I cleaned area. But all the read circled areas are covered with black oil (completely black):Īlso, when I was working on the transmission cooler lines and fluid change, the areas below these areas are also covered in black oil. Now, I realized that I may have the dreaded timing cover leak: I should haven taken a picture before I cleaned the area with 4 cans of carb cleaner - because I wanted to make sure there is oil leak. I think I really got a bad deal with this truck (bought it in Jan): first the power steering fluid is mysteriously over filled and spilling all over the place then I found a big transmission fluid leak, turns out to be the transmission cooler outlet line has rusted through, so I had to replace both cooler lines and change the fluid (only about 1 qrt old fluid came out so my transmission could have blown up if I hadn't noticed the leak for another two months). ![]()
