my cars been overheating lately and dont know y i have to put coolant in the radiator almost every week but the ? is where could it be coming from the fan turns on just replaced my upper radiator hose i did that check 4 the thermostat and is good is there something else i forgot to check ??? thanks

 

Do you ever notice coolant dripping when it's parked? If no, then it could be bad news in the form of a leaking head gasket.

 

dito.... keep an eye on where ya park..... look for some green trailer... could be anywhere.... could be cracked overflow tank, split overflow hose, or just a little leak in the radiator..... or acrack in the heater core or its hoses....

id say just for safety id get some radiator stop leak and pour that into the system... and hopefully if its small enough it could stop it....
just a posibility... if that doesnt ya gotta keep tracken it down.....

 

if coolant is missing and you cant find it you need to check your oil.

Over heating
missing coolant

those 2 in tandem sound like a dead ringer for a blown head gasket.

 

Or it could be a bad water pump?

 

or the thermostat could have gone bad?

 

ya its just one of those things thats trial and error.... try the cheap stuff that you can get to easy enough and hope its the problem!!!!!!!!
