Is it ok to change spark plugs and wires if?

i gotta drive about 45min to my friends house with my car so should i let the engine cool down before we change the spark plugs and wires on the car or it dont matter?Is it ok to change spark plugs and wires if?You MUST let it cool down COMPLETELY.



Your cylinder heads are almost certainly made of aluminum, which is soft to begin with. It only gets softer as it gets hot. Plus, hot metal expands so you're plugs will be in tighter.



Taking plugs out of a hot engine can strip the spark plug threads. Let it cool completely before you begin.



Be sure to use some anti-seize on the threads as well, to help reduce the chance of having damaged threads next time you do the job.Is it ok to change spark plugs and wires if?would be the best idea to be taking out spark plugs while the engine is 200 degrees..

Only time I would suggest a warm engine for basic stuff is cleaning the engine bay and oil changes.Is it ok to change spark plugs and wires if?It will certainly make it a lot easier. After a 45 minute drive, that engine will be hot. Working over a hot engine is not fun.Is it ok to change spark plugs and wires if?Don't bother buying new wires unless the original ones can be proven to be arcing. It is a waste of money. Most OEM wires can last for the lifetime of the car they are installed in. One reason to allow an engine to cool before removing plugs is due to the difference in materials between the aluminum alloy in the head, and the plated metal in the spark plug. If you are not using Bosch Platinum wire, Fusion or Nippondenso Iridium or Twin TIp plugs, you are wasting your time. Because you engine will not produce full power, lowest emissions, and best economy. Use Gum-out spray to clean your IDLE AIR CONTROL VALVE and throttle body prior to installation of new plugs. This will leave unwanted carbon material on the OLD plug tips, and not on the new ones!!! Good Luck!!!
