Question about 1990 Chevrolet Cavalier
My Z24, is it a interference or a non-interference motor? It died 4 months ago, We are pretty sure that it is the timing cahin gears, we need to know if it is intrference or non-interference motor. HELP!! And how hard is it to change the timings gears parts?
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.

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.
