new thermostat, flush and fill
Hello and welcome to Just Answer.My name is XXXXX XXXXX X will try to assist you with the no heat issue.If the engine is coming up to temperature and noting that your car is a 1998, there is a good possibility that the heater core is restricted.Check the two hoses that lead into the core at the firewall. Both should be almost too hot to hold and of equal temperature.If one is is colder than the other then the core is restricted and you will have no heat.Flushing the system will often not solve this.In order to clean out the core it will need attention on it's own.Undo the hoses and put on a couple of hoses on the end of the core pipes. Pour in some solution to remove lime buildup such as CLR.Let it sit for a few minutes and flush it out well.The use of compressed air would also be a good idea to blow it out.Your questions or comments are welcome.Thank you.Bernie.
someone told me the heat exchange door was not working
OK, you did not mention that previously.When you move the control from hot to cold can you hear anything moving or a change in air flow pitch?Have you already checked the heater core?
no i yet to check the heatercore, but where would the heat exchange door be located?
Hello.Could you please answer my question to you on the movement of the heat door?This way we can determine the cause of the problem.There are many components that also control the door movement.If we can determine if it is or isn't moving we can get to the root of the problem.Thank you.Bernie.
if the core was clog would it not overheat because no circulation are these reply also going to mty email?
Hello.No, a plugged up core will not cause an overheat in most cases.Check out the heat door for movement and the heater core hoses and get back to me.I will be on for several hours yet today so no rush on my part.Thank you.Bernie.
i will try moving it from hot to cold and see what happens
how will get back in touch when i find something out
Hello.This dialogue will remain open for us to communicate.I will be on for most of the day tomorrow.You can reply to me anytime here.thank you.Bernie.
i check the temp control and it does not change sounds until it reach the lowest setting 60 degree
So it does move.Have you checked the heater core supply lines?
no i did not check those as it is to dark and cold now will check on sunday.
thanks for your help, keith
OK Keith.See you tomorrow.Bernie
i just got the car up to operating temp and check the heater core lines one is hot and the other is cold what is my next step?
Good morning Kieth.Follow the process I described before on flushing it out.I use a couple of pieces of heater hose long enough to slide over the heater tubes.Then I pour in Muriatic acid in one of the hoses and let it sit for a few minutes. Then I flush it clear with water and blow it out with compressed air.Muriatic acid is very strong and safe use is very important. Safety goggles and protective clothing is essential.CLR is much less potent and will usually work. It may take a couple applications.Questions or comments on this subject are welcome.Thank you.Bernie
hoe do i get to the lines as they are way back on the firewall can i take the top shroud off?
Remove what you need to access it Keith.I think it is the air cleaner ductwork and the top cover.
did the clean out with muriac but still very little heat
Hello Keith.Was there much stuff come out with it? Did it improve the heat?If it did, it may need to be done again.Bernie
i will try it again, as there is a little heat not much stuff came out
Are the two hoses equally hot now with the heater on high fan?
yes they are
Well it must have improved. One was previously colder.Have you taken the car for a drive yet to test it?
yes i have put about 100 miles on it since
Give it one more try Keith.How much did it improve?
Hello Keith. Here is a service bulletin that may relate to your issue.
DATE: Feb. 4, 2002
A vehicle may exhibit **low or no cabin heat,** engine overheating and/or coolant bottle damage after service has been performed on the engine cooling system This may be caused by lack of complete ** filling or** refilling of the system with coolant/antifreeze.
When refilling the engine cooling system after any service operation which required a complete or partial draining of the engine coolant, the following Repair Procedure must be used to ensure a complete fill of the engine cooling system. This is a Repair Procedure clarification.
will have to try this first
another question the abs and trac control lights stay on
OK, let me know.
