Have a compression test done to determine the extent of engine damaged from the over heating. I suspect that the compression will be very low from ring failure and the heads cracked or blown head gaskets from warped head/s. When this happens the prognosis for damage is not good.

SOURCE: 2003 Cuts off when hot, will not start untill cool

My 2003 nissan sentra would get hot and stall out even in middle of highway doing 70 mph. The guages would go up and down. Would not start up all the time after stalling. had to cool down first. Nissan said it was head gasket, and wanted to charge 1000.00 for the job. I took to local dealer who charged me 550.00. Works fine ever since. Nissan dealer said they do like 3 head gaskets a week on the sentras. They have crappy ones in original parts. They have not recalled though.

SOURCE: No interior heat until I start to drive

You most likely have an "AIR LOCK" within the Heater Core. This requires one to pressurize the Cooling System and loosen the heater hose at the HIGHEST POINT and bleed the Air out of the Heater Core. I am not familiar with the Nissan but have encountered this problem numerous times over the years. Most late model vehicles are equipped with Air Bleed devices which must be utilized any time coolant is drained and refilled.

Most all reputable Auto Parts stores sell and/or rent a pump that temporarily replaces the Pressure Cap that may be utilized to pressurize the system for this purpose. If you don't feel capable of performing the bleeding operation take your vehicle to an ASE Certified Mechanic and have it done correctly.

Load placed on the engine takes place when the Compressor clutch engages. It will not engage if the system charge is too low on freon. It needs to be checked with a gauge, I think that may be your problem.

2006 Pontiac g6 code p1258 . The temperature gauge was fluctuating while driving from overheating to normal operation temp but no actual sign of overheating . So I replaced the coolant temp sensor ran it...


I suggest changing the cooling thermostat to make sure it's not getting stuck causing temporary overheating and flush the system and put fresh coolant in.
The guage will go hotter then go back to normal every time the thermostat opens to let cooled water into the engine block which is normal. Time for concern is when the guage goes hot and stays there along with bubbling sounds and coolant overflow onto the ground. Which you probably already know.

Van blows warm air then cold air temp needle starts to rise towards hot


There are many different temperature ranges of thermostats. The old one may have been a 165 degree thermostat. The new one may be a 195 degree one. You will then notice that the gauge will run higher than it used to.

My 1999 cutlass oldsmobile started running hot...repaired the thermostat but the fans don't come on...what could that mean?


There are two thermostats.

One is the Coolant Thermostat, and this regulates the circulation within the engine block, heating core and through the fan.

Then there is the FAN thermostat which is actually a switch which tells the fan to come on when the coolant reaches a critically hot temperature. This is the one that you need to replace which sounds like it has an intermittent fault. It is normally located in the radiator.

Also you need to check the fans themselves to make sure they are not faulty. Take a length of wire to the battery and cycle the fans for varying lengths of time to make sure there isn't an intermittent fault with them.

My son said that the temp guage was reading about 2/3 of the way hot. After he turned it off the fan kept running for a couple of minutes after he turned it off. This is on a 2007 Pontiac G6.


The fan will run after the engines has been turned off. The temperature gauge at 2/3...It normal when the engine ran for two minutes then turned off. It could have been hot day, air conditioner is running, stop and go traffic, drive really slow. many factors affect the temperature of a engines. One way the manufactures fix some of this overheating problems were to install axillary fans, also increasing the psi on the coolant system from 212 degree F, to 240-5 degree F. Buy doing this the half water/half anti-freeze will not boil off. Just make sure that the bugs are removed from the front of the radiator and the air flow isn't restricted. GB...stewbison

Have a 2007 pontiac g6 3.5L engine. Replaced water pump; very simple procedure . Drained system and all but now it won't take the normal amount of coolant . Just fills the expansion tank and no more ....


if you are sure there is enough prestone in the radiator,start the car and let it warm up till the thermostat opens and the fluid level drops,then continue to fill the bottle.most newer vehicles have a valve you can open called the bleeder which should be somewhere on top of the metal coolant lines above themostat level. hope this helps

No heat while idling, but when driving a little heat comes and as soon as we stop rolling there is no heat again....fluid good...new thermostat...engine temperature in normal operating range..


first check and make sure coolant is at proper level. if the top radiator hose does not get hot, then change the thermostat. this may be sticking, and the problem. have a good day!! also make sure water pump is ok!
