Your coolant level is low.
They stopped making the Lebaron in 1995...
An air lock, defective thermostat, stopped up radiator, Restriction of air flow across the radiator are all possibilities. On Chrysler products they have a 2 speed fan and if the high side doesn,t work is also a possibility.
No. The Chrysler PT Cruiser was stopped in 2010.
I believe I have an answer for this, or somewhat of and answer. I have a 1995 Chrysler LeBaron, and I have had it stall on me while it is running, or when stopped at a stop sign, then it not be able to start back up for a while, or sometimes it will start right up. I googled it one day, and what I stumbled across was that it supposedly is the fuel pump. The 1994 and 1995 LeBaron has a faulty issue with the fuel pump that causes the engine to stall, and a few of the warning lights to come on. I have had this happen to me about 4 or 5 times, and all in convienient locations. I found this question googling for more information on the topic. If I could site the page I read that at, I would. But if you google it, I am sure you will come across the same info I have. OR, try calling your Chrysler dealership. I have yet to do so, being as how ours just closed in town.
fuel pump relay may need replacing
No, Chrysler stopped Plymouth production in 2001.
The Chrysler Valiant was produced by Chrysler Australia in 1962 and production was stopped in 1981. In the United States the Valiant was re-branded Plymouth Valiant.
It is very common for vehicals to over heat in traffic or sit still situations because the engine is running at a low RPM and thus circulating the water slower causing it to hold temperature, also not much air passes through the radiator at a sit still the only air moved is by the fan which is not always very reliable. The AC compresser is not easy to turn and causes the engine to work hard in order to make the AC work. ==Rad. cooling fan== It may be that your radiator cooling fan is not working.
Your spedometer is broken.
the oil sender unit need to be replace.
No. They stopped making 1989 models when the 1990 model came out.
The idling speed could be set too low.
