The first thing you need to do is check the cooling system coolant level. If it is low or empty, there is not sufficient coolant to cool the engine or to transfer through the heater core to supply the cabin with heat. Fill it up and check for leaks. Once leaks have been repaired, change the thermostat, engine oil and oil filter. If it is full, you may need to change the coolant due to its age, as well as the thermostat, engine oil and oil filter. The reason for the oil change is due to the thermal breakdown of the oil in overheating conditions. Also inspect the water pump to ensure it is being driven by the belt. You may also have air in the cooling system that is causing all your problems. Generally only happens when the cooling system is improperly filled. Make sure you add the correct mixture of coolant and water. Incorrect ratios will cause you similar problems.Coolant protects the cooling system and the water dissipates the heat.

I'd suggest having your flywheel checked, if it's an automatic transmission, after you get your starter checked and/or replaced.

FRONT STRUT MOUNTS,TIE RODS,WHEEL HUBS AND STABILIZER BAR LINKS NEED TO BE CHECKED FOR WORN OR BROKE!!

What part are you trying to get out?

it might be a knocking sound on your engine

yeah get a screw driver and un screw the screws and then take the panel off and take the wires un plug them and plug them back up see if that works

Take it back to who ever is guessing what the issue is and tell them to fix the intake gasket. IT was not installed correctly or torqued right. Depending on the mileage you may get a free catalytic converter. They are rated for 10 years. Contact a dealer about it. But if you had a blown head gasket and coolant got into the exhaust, the cat should be replaced. Silicon additives in coolant ruin catalytic converters

check for a wiring problem to the HO2s sensor . Run fault codes to determine which area is causing the problem

Could be you selector switch.

code P0128 :say that the engine is not running normal temp.but less.how the pcm can say that . it's receiving info from coolant sensor. 2things one the coolant sensor is telling the right temp. or the thermostat don't. Change thermostat and see if it change the condition.
