How's the water pump?
check for a clog that means water is not circulating
I would start off with replacing the radiator cap if it don't have one then the cap on the refill tank ,this may fix your problem .
Try replacing the radiator fuse relay
if you have heat and and it is working OK. and if you squeeze the lower radiator return hose and feel water flowing. most likely it is the electronic fan not coming on.
Can be leaking from a hose not secured properly or a hole in the system.
Thermostat needs to be replaced, it is not opening (most common). Is electric fan on radiator running normally from time to time?
Perhaps plugged radiator - have it boiled out or replaced
Could be your electric fan on the radiator is shot, or the relay is bad.
Thermostat stuck closed? Low coolant level? Radiator plugged or dirty? Water pump not working? Cooling fan not working? Defective radiator cap?
check radiator for small leaks or cooling lines which would most definitely cause it 2 steam when running after awhile
What year and make of car? My 1997 Honda Accord's radiator fan kept running after it was shut down. Upon inspection of my system I had low coolant and no pressure. Replaced the radiator and have not had an issue since. Check and top off your coolant, if it continues then I have no clue as to the problem.
Yes. Fuel pressure test. Make sure the pump is running, fuse is not blown, filter is replaced, relay is good.
