Is it a v-6 or an 8 cyl?HINT-4.3L would be the V6. That one is throttle body injected and would be a little different from the carb. models of which the other answer is correct for...V6 is Rare , but just in case.......
Probably , but while you're there , remove the head and let a machine shop replace the bent valves. It's listed as an 'interference' engine , which means when the belt breaks , valves hit the pistons and bend or otherwise cause damage. Sorry , but if my info is correct , a good used engine might be the better option.
Forget about the gauge and actually check the coolant! gauges can be incorrect if coolant level is not right.
Have scanned for codes and post for assistance.
How was the system charged initially ? Evacuated , then after new comp. installed (with appropriate amount of PAG oil) was the system vacuumed down for at least 30 minutes? Then charged with a calibrated machine to capacity spec(I believe .55Kg)? The reason I ask this first , is because if the system is even .05Kg low , it can have those symptoms. Also do the under hood fans both come on with A/C switched on? If only one is coming on , that issue needs to be diagnosed as well, it too may be causing performance problem.
"wehave a es 300 problem !no info!!!!"....................A little more detail may go a long way! Like , are you cranking it when it has no spark? How many miles on it , when & under what conditions was the 'no-spark' noticed?.................
Bad fuse , faulty PCM (regulator) , Faulty harness/wiring , all possibilities. Oh , and has the alternator itself benn tested?
Remove hinge bolts and disconnect harness.
What's your skill level? Could be bad plugs , bad wires , bad coil ,bad rotor/cap , bad distributor , low fuel pressure , low oil level , bad ground connection on engine harness(underneath , by throttle body).....The more you can isolate and narrow down the specific conditions which cause the problem(misfire) , the easier it will be to eliminate certain items. Also knowing what has and has not been done as far as maint. , would be a help. HINT:::: porr quality aftermarket parts , no matter how new , can cause same symptoms.
First question...Has it EVER had ANY kind of body work on that side or that rear corner?
