It overheats any time the heat is not running. It has a fairly new thermostat. The radiator did have a large leak but I used stop leak and it appears to have fixed the large leak. However I have had problems with the coolant system since as it only keeps the engine cool enough while I run the heat.when it is not on it gets so hot that it forces the overflow hose off and all the coolant evaporates out.
Car has 115000 miles on
It starts but won't drive and when in gear it makes loud awful noise. This started after the wheel baring damaged.what is the problem?
It was a rainy day and floods.I had to drive through it .it causes damage to the fender liner.but the loudest clinking noise starts and some metal pieces fall out along with some greasy little marbles. Now my car won't starts it just doesn't go.what is the problem?

Hear air when applying pressure to brakes. Brakes go all the way to floor. This happened right after slamming brakes to avoid hitting another car. What happened? And how do I fix it?
I replaced the battery- replaced the alternator now every time I turn on the head lights or heater all the dash instruments and radio stop working and the battery drains fast checked all wires and connection and belt tension and all are good
After flushing the system, replacing the thermostat, heater core, and resistor, we do find that the air is warm but does not really seem to be coming out of anywhere. The fan is blowing and on high but you can literally take a tissue and not even see movement from the lack of force. We also attempted to check for trouble codes on the heater and ac and received an 11 which seems to be related to the blend door but when tested by a mechanic the actuator and blend door appeared to be working smoothly. A Honda mechanic has suggested that the heater sub assembly might need to be replaced but as there is no physical damage to this we are a little skeptical and really do not have the money to purchase this $300 part for nothing. Any other thoughts or suggestions?
I'm interested in learning if a magic eraser will cause damage to my car either on the interior or exterior. I haven't been able to find any information through Google searches on the ingredient lists, etc. Mostly just things "debunking" the ingredients. Anyone know if the magic eraser will damage paint or interior? Thanks in advance!
I have an oil leak as well.
car wont go in gear or start unless in neutral. i bought the car two days ago and am frustrated! its sitting on the side of the road.....
The dealer whom I bought the car from is sending the parts. I assume they will be new. Should my mechanic accept aftermarket parts if that is what the dealer wants to send? Thanks
when you park the car the brake lights will not turn off. the car is turned off and they stayed on.

just change my fuel pump and filter because
car was shutting off both on idle
and driving,nothing has change since,
it still does the same,though has gotten
a little better but on acceleration while
doing a drive test it seems to jerk for
a few seconds while holding the pedal then releases,this is at 3,000 rpm reading. the car has no problems starting,been starting it everyday and just driving around my resident area.
the shutting off only occured once but the jerking thing continues at 3,000 rpm on acceleration but it does releases
and the car continues to drive normally.
nothing technical as i know,whats causing this.
