Yep. Might even cause the engine to stop running forever when it overheats and seizes up. Your engine loves you and wants you to stop asking questions and fix the coolant system. Something is causing you to have low coolant levels and you need to figure out why. Take it to a reputable shop for diagnosis.
your engine is running much to rich. jmmmzzz.
An Aisin/Warner AW4. Made by Toyota. Variants of this tranny are used in Landcruisers, Lexus, Supras.
A 2001 Jeep Grand Cherokee 4.7L would have a 545rfe transmission.
A cracked head could be the cause of the problem. This, along with a cracked head gasket would allow engine coolant to enter the oil supply. Coolant and oil do not mix well and over time, the oil looses its capability to lubricate. Check your oil for white spots and check your coolant reservoir for oil residue.
I have a 1994 Grand Cherokee with a 1990 Cherokee 4.0 engine in it.. So i wuld have to say yes to your question.. ( i did not know it was from a 90 Cherokee until i had to buy some parts for oil change and none of the filters for a 94 would work.. :-)
50 50 coolant is what i use- would suggest no more han a 60 40 mix.
A Cherokee would have the AW4. A Grand Cherokee would have a 44RE.
I would think so.
Yes 93 to 95 are the same
YES....
It could be but most likely the engine is overheating. Could also be that the cap is not holding pressure and needs to be replaced.
Low coolant or a defective sensor
Yes and no. As long as the motor is the same, the harness should be the same.
this would typically be for security. do they eventually go off though is the quetion
