Hi.
this could either be a faulty thermostat, or a partly blocked radiator.

best thing to do would be to remove the radiator and flush it with water until the water runs clear, and change the thermostat at the same time. the thermostat should be fairly cheap and the thermostat housing is normally found where the top radiator hose attatches to the engine.

if this does not cure the problem, feel free to ask for further advice.
good luck

Heater blows cold air only 2006 Dodge Charger?


Check all vacuum lines first for any possible leaks especially if you have a flow control near firewall or hoses going through firewall. If you feel hoses going to heater core, are they both hot to touch when engine at normal running temperature? Coolant level is up, and been bled properly? Did you have to add coolant lately for any reason?

I have white smoke coming from the tailpipe and a decrease in gas mileage on my 2007 Nissan Quest.


Does the car overheat? Has it overheated in the past prior to the white smoke? Is the coolant level low? Does it run poorly? Is the white smoke constant or initially at start up? If at start up and then clears it is possible that it may just be condensation. If constant and has a sweet smell and you can answer the above questions with a yes then it is possible you have a blown head gasket. Good luck.

My thermostat light comes on constantly blinking red, my car runs hot occasionally, it doesn't leak any fluids but i have to fill the coolant more often than normal. What are the possible problems?


You may not be able to see a leak because it may be a pressure leak. In other words it will only loose coolant while the engine is running and the system is under pressure. One other problem may be a leaking head gasket. If you notice white smoke or staem that stops shortly after starting this may be a problem. For a small pressure leak, try a contaner of bars leak in the radiator

Car running hot. want to bypass relay to keep fan running constant.


It's most likely your thermostat or possibly your radiator cap. neither one is an expensive fix.

I have a 2002 525i bmw, sometimes when i crank up the car a big pile of smoke comes out, and thens goes away. the car runs great sometimes and then sometimes when i make a turn i can hear the valves rattle...


It doesn't have to run hot to be blown. Sounds like you have oil getting into one of the pistons when you make that turn. After a couple of times, it ruins your plugs and that's why you're getting a mis-fire. It sounds to me like the engine itself is blown. The pistons along with the plugs are firing (burning the oil that gets into the cylinder walls. It's time to look into a rebuild.

2004 Ford F-350 6.0 Turbo Diesel - Severe Hesitation at Take Off


Some of these engines have a place to drain water out of the fuel system.. Some fords actually have a stick under the hood that you push or pull That opens a valve on a water collection bowl. It's not labeled usually. It might state where it is in the owners manual under fuel water drainage or something similar.. if that bowl is full it will cause hesitation... If it gets over full it will cause runability problems. Another possibility since you said it's black smoke is one of your injectors is sticking at low rpms and squirting raw fuel into the cylinder till the rpms get up enough to burn that fuel off completely then then the injector works a little better.... Do you notice any missing... Feel something under the hood like the air cleaner housing and make sure the vibration is constant and doesn't have a small sudden shake and the n smoothe... And then a small sudden shake again.
If it does have this shake you can trouble shoot which injectors by with the engine running loosening an injector line and seeing if the engine runs worse or not.. If it runs worse tighten it up and move to the next line till you unscrew one and feel and hear no difference... When you find that one that's the injector with the problem.
