2002 Dodge Neon 2.0L several issues need help with

Question

Power steering seems like an issue when turning right it has a lot of play not to mention whines like it will go out soon but the left turn of the wheel feels fine & doesn't whine. Also vehicle runs hot. Dash gauge does not show it however the radiator top seam is cracked & coolant bubbles out. The system has recently been flushed & refilled. I know radiator needs replaced but the temp sensor is still not showing its overheating. Where is the temp sensor located on this vehicle and should I replace it or just the radiator? Also bottom & middle motor mounts have been replaced along with new battery & alternator. There is oil on & around the spark plug tubes. Got a valve cover gasket to replace it is there a cause other than leaky gasket that could cause oil there & would it be the cause of the rough idle on starting vehicle?

Answer 1

If the power steering whine one way and not the other , you may be up against a faulty rack and pinion.  Radiator cracked and bubbles out, The whole purpose of keeping the cooling system under pressure is you increase the boiling point of water (if you use water of coolant) water boils at 110 degrees increase the pressure of the cooling system 10 pounds you increase the boiling point to 220 degrees. that's is why you replace the radiator first.as for the oil leak at the valve cover the sparkplug tube seal tends to leak into the sparkplug well this would saturate the ignition sparkplug boot drowning the secondary ignition. spark and cause sparkplug wire failure
