My car overheats. The overflow tank is not full, dont see any leaks in any lines, no abnormal smells, the fan runs, antifreeze levels correct and flowing properly, I havent flushed the engine yet, but is that crucial that I do?

Welcome to the forum, check coolant flow through radiator, if nothing, check thermostat and water pump. Are you loosing coolant?

I just started to notice a leak under the middle of my car. My husband checked my oil but it was fine. My car is overheating and having any noticeable trouble driving. Any suggestions? I will take it to a mechanic later this week, is it safe to drive til then?

As long as none of the fluid get too low or get on anything hot, you may be fine in waiting.

I have an 03 ford Taurus I brought from a couple who had it sitting for a while I had the transmission rebuilt and now its overheating I replaced the radiator and fans. But it will only overheat at idle n cools down while driving. It doesn't have a cracked head gasket I have no clue what else it could be. Please help! Thank u

If the fans are running and the thermostat was replaced, tell me this. If you rev the engine to around 2K RPM's, will it cool down? Have you checked to see if the radiator is partially plugged?

I went threw a shop they replaced the radiator so I have no clue n the car is still in the shop now so I can't rev it up I'm getting out tomorrow I have no money to keep handing these people n they still can't fix the problem. Today he said the last option was to take the heater coils out n see if that stops it from boiling but I won't have Any heat n he put blue devil engine seal to deal it in case there's a crack in the head gasket so I don't know where to go from here I put too much money in it just to sale it

Okay, this makes no sense. If the fans are turning on and the temp drops when the engine is revved, it sounds like the water pump isn't doing its job at an idle. Is the belt that turns the pump tight?

My friend has a 2003 taurus /3.0 l engine. It overheats on idle but when driving never gets to operating temp. His mechanic says the head gasket is sucking air yet coolant doesn`t appear to drop

Check if the coolant fan is coming on, if okay try replacing the thermostat-check the radiator if its clogged and also if the water pump is circulating coolant

So it was overheating before the repair? This overheating was not caused by a large coolant loss from the water pump leaking?

So there is no more coolant loss? Are both upper and lower radiator hoses getting too hot to hold? Is the radiator fan working correctly?
