SOURCE: Need diagram of engine for 2002 cavalier z24

Its the upper radiator hose should be located topside beside the engine oil dipstick,any smaller hoses you have running into the radiator are heater hoses, the lower radiator hose is where coolant enters from radiator into engine and is pumped up with water pump thru water jackets in engine and eventually returns thru the upper radiator hose which is most prone to damage due to splitting and cracking, I hope this helped.

SOURCE: how to replace a timing chain 2000 chevy cavalier

I am familiar with that vehicle but generally with timing chain replacement, the engine needs full access for pulley and cover removal and in some cases the cylinder head requires removal.
Generally timing chains last so that they only need replacement at engine overhaul and it is not an economic proposition to have to replace a chain unless some relative degree of engine work is also required at that time. 

Engine timing chains generally have a tensioner on them which maintains tension, but some chains can wear significantly and cause timing cover to be "ground away" because of "slop".

If the engine is making the noisy rattle of the timing chain against the cover etc, I would schedule a top overhaul (head, machine, test and valve grind) with the chain replacement dependent on mileage with the degree of action.

Some simple simplex timing chains (type of chain similar to motor bike chain) may be replaced without dismantling the engines but I would expect your chain would be a "duplex" dual sprocket type, these are most common. 
These chains are not generally expensive but replacing them can involve a fair amount of work. 

Good Luck and hope this helps, Others will have different ideas.

Your lockup torque converter is bad I believe. When you shift from Park into any gear it will die.

Does my 2003 dodge caravan have an interference engine


Not sure but if doing belt yourself I will give you important tips. 1) before removeing T/Belt set engine to TDC nr 1 there should be marks on the crank and cam (s) gears that line up with a mark on the block / head. 2) prior to removeing tension to belt get liquid paper & mark cam gear(s) & crank gear to point on block / head. 3) mark T/Belt to cam(s), crank, balance shaft if fitted. 4) release tension & remove belt. 5) transcribe marks from old belt to new belt & make sure correct amount of teeth. 6) fit new belt so YOUR marks line up. 7) have tensioner suply presure to belt. 8) turn motor twice by hand to make sure pistons no hit valves 9) Make sure YOUR marks line up if YOUR marks line up it has to be right. 10) Very IMPORTANT if spring tensioner lossen locking bolt again to take up extra slack in belt. 11) tighten locking bolt. 12) put back together.

I have a 84 nissan z24 ,problem I am having it stalls when attempting to start the engine sounds like it is really heavy for the starter to turn the flywheel. Once i get it started from 1st to second it...


How about the coils? Also check the distributor cap as it has 1 carbon pin that is off center and can pop out causing damage and a non firing condition. You say its a nissan z24, I suspect you mean the engine is the Z engine because I am pretty sure chevy made the Z24 vehicle and datsun/nissan made the 240, 260, and 280Z's.

Is the 3.0 in a 1996 dodge caravan an interference or non-interference motor?


According to Dodge it is non-interference. Did you loose your timing belt and wonder whether the valves are bent ?
Please let me know

Timing belt is broken. Interference or non interference motor?


Most Ford vehicles from 1985 and up have enough valve clearence so the valves do not get hit when the timing belt snaps. Since I worked for ford for many years I have only seen one with valve damage and the youg man said he was driving his car really hard at high RPM's. I believe you will be okay on your engine as long as when the belt broke the engine was not at high rpm's. If know one has told you those engine recommend a timing belt replacement every 60k. I hpe this helped and I hope this fixes your problem. Good luck, Roger

How can I tell if the valves are bent from my timing belt breaking?


It depends on a couple things. First is whether your car's engine is free running or interference. I'm pretty sure it's the 2.0l 4 cylinder if so then it's whats know as an interference motor. This means the piston and valves can interfere with each other and cause damage if the timing belt is broke. That doesn't mean it did just that it can. There are a couple ways you can use to confirm whether they are bent or not. But the only one that will be absolutely sure is to inspect them. All other options like a compression test will require the engine to turn over which may cause more damage if in fact the valves are bent.
Hope this helps.
