No. It is a gimmick. Do regular oil & filter changes instead.
If your asking about a heater core for a car. you pretty much have to pull the engine to get at it. as it is part of the system, it should get flushed out when you flush the system.
can crack the engine.
Do you mean flush the oil (not recommended) or flush the coolant?
No they are completely different. A engine flush will only clean the engine a transmission flush will only clean the transmission. These two components use two different kinds on fluid therefor they can not be mixed together.
Buy one of the "flush in a can" products and follow the directions exactly. if you want to do a machine flush your dodge dealer should be able to help you out. it wont be cheap, expect to pay between $100 and $150 for the flush and an oil change.
Not far, anyway. The engine flush is not engine oil ... its only purpose is to, hopefully, clean the inside of the engine areas. That's why it's called "Engine Flush" and not "Engine Oil". Get it out and put the new oil in soon.
Add Engine Flush to the motor oil at running temperature before changing the oil. After adding the product, allow the engine to idle for approx. 10 minutes. Then change the oil and the filter. Engine Flush is compatible with all commercially available motor oils. We recommend cleaning the engine interior with Engine Flush before every oil change.
drain all coolant from system. flush with water until clean water is comming out of engine. fill rad with water and run engine up to temp. this should help remove the antifreeze from the engine. drain water out and run water through system again until clean. add new coolant to system. should be good. use garden hose to flush out system
At least every 50,000 mi. I would flush it at the same time.
You will not damage the engine but you can damage the radiator if you use any high pressure. If you only flush and apply no pressure you will do no damage. Use a chemical flush and a water hose and you will be safe.
Ive never heard of draining coolant plugs except on a diesel engine . Once you drain the coolant and flush the system it should be fine
