Question about 1998 Dodge Stratus

Heater problem and engine light on

The engine light has been on for over a month, the gauge says the car tends to run hot but it goes down when I turn on the heater. Recently, the heater will blow cool even though the car is warm and when I turn off the car, it sounds like a old coffe pot behind the dash board. The coolant level is fine and there is no leaks that I have found. It's a 98 Stratus with the 2.4 DOHC. I'm guessing heater core. What do you think?

I'm thinking Rad. Check to make sure your rad fan is working properly and coming on when it should. When you turn your heater on & it cools the engine down, that's like a small rad too, and by running it through your heater core, the blower is dissipating the heat, the way your rad & rad fan should be. Double check you don't have more serious problem too. have system pressure tested. Have you been noticing any loss of coolant? Thermostat changed lately, if not, now would be a good time, when rad done. If all else checks out, I'd replace rad.

Your engine is overheating, that is why the check engine light is on almost for sure, have you checked the cooling fan for proper operation? turn on the AC it should run after a minute or two, also the thermostat may be sticking and causing this. The noise you hear is coolant boiling, I know this for certain, it is not a guess, have this checked ASAP or you will blow a cylinder head gasket.

F you are referring to the Check Engine Light, then there is a problem with the emissions system. Have it looked at by a professional with the tools and knowledge to diagnose the problem.

Engine light comes on heat blowed cold air and car runs hot and wont crank now


Number 1: get the code; even if they light turns off an on, the code will be stored in the computer.

It sounds like you could have a variety of issues and more information needs to be given. How is the car running? Does it run & idle perfectly or does it stumble?

Running hot?


2 possible things. 1st(cheapest) you have air in cooling system. Need to burp it. 2nd(expensive) you may have blown head gasket. I tend to think air is in cooling system and your level is low.

My 1999 Chevy Malibu runs hot? It started when it overheated. We changed the thermostat, then water pump, then temp sensor gauge and the temp gauge goes high but only when the heater stops blowing hot...


Air pockets will make the guage do that, and also cause your heat to come and go. Also, a poor radiator, as in rotting, or plugged up, will cause high temperature issues.

I have a 2000 Mercury Cougar and the gauge inside tells me that the engine is over heating, no heat is coming from the heater when I turn it on, the fan for the engine is running at full blast, the engine...


Hi,

The overheating and lack of cabin heat both point to a failed engine thermostat which would be stuck closed. At the warm up stage, the coolant stays in the engine block to bring the engine to efficient operating temperature, then it opens and circulates the coolant through the radiator and heat core. If the thermostat is stuck closed, the engine will overheat, and coolant will never reach the heater core, and you will not get cabin heat.

Blinking oil light at idle which goes away during driving could be a low oil level, but may also be a drop in oil pressue. You could have a clogged oil fliter (at best) pickup tube, or a failing oil pump.

the first thing to try is turning the heater upto full heat(a/c off)if the temp guage goes down THEN CHANGE THE THERMOSTAT...(hot oil,if too hot, is thinner than the normal sae rating so the oil pressure will be lower.otherwise no real problem.

Engine overheats when heater pipes connected


I think you could be right about there being air trapped in the system.
Or the heater core(radiator) is plugged.
Either way you need a pressurized radiator coolant pump to put the coolant in without air being trapped.
Although,i have seen it done by jacking the vehicle up high enough that the radiator was now higher than the heater core level, and then the coolant was put in.
But this is dangerous to try.
