getting stuck as to where to go next. im obviously lossing coolant but no puddles no obvious leaks no drips and not burning it. car is running hot when driving and i dont think the fan is going on. can anyone tell me where/wich relahy is the one for the fan. i checked the fuse and its good. also if there is other switches etc that i should check before replacing the fan assembly. also low coolant light dosnt come on. thanks in advance for any help.
 


If you're losing coolant you're either burning or leaking it externally.... unless someone is opening the cap and siphoning it out.
 
if it runs hot and loosing coolant. there's a chance your head gasket is leaking coolant into a piston bore and burning it. or a cracked head
 


I dont have that same issue but i have a similar one.. one day my 2000 grand prix GT 3800 overheated into the red zone in my driveway. right away i changed the thermostat and did a flush and fill just to be safe. Since then it has always run hot. driving at about 40 mph it stays about 210 -215 but when idling or slow driving it runs anywhere from 210-230. i recently changed the water pump and the coolant temp sensor and same problem occurred.. i thought maybe it had an air pocket in it but ive bled it out several times and tried to burp it but nothing has helped my problem. The gaskets arent cracked, oils clean, no leaks. top radiator hose to thermostat doesnt feel like it has a lot of pressure tho..It is 80-90 degrees outside right now... is this normal or can i do something to bring the temp down below 210? PLEASE LET ME KNOW! thanksss
