[quote=Yontrop]That is the KA24E, 2.4L, single overhead-cam engine, 12-valves (3 per cylinder). It has a timing chain. The original chain tensioner is plastic, but the replacements are usually steel. The engine makes 134hp and 154ft-lbs of torque.
The 'hardbody' is just a reference to the construction. It's just a very rigid body-on-frame design, and it's known to be very robust.
The timing chain makes a chattering noise when you first start the truck after it sits for a few minutes... this is normal. The noise is the chain operating without any oil on it, and it takes a few seconds for it to pick up oil.
And lastly, it's a great truck.
thanks for the info but is this a interference engine?
