I have a 2001 Jeep Grand Cherokee Limited 4X4 ready fitted with Roadmaster Strerling tow equipment. Unfortunately, I have no owners manual and am getting conflicting opinions on the positions needed for the 4X4 selector and drive selector when towing. All say the 4X4 selector should be in Neutral Buy Instagram Followers UK Get free Likes on Instagram from 0 59
Check your radiator for external and internal obstructions (leaves, bugs etc on the a/c condenser or leaves between the condenser and radiator, rust or calcium deposits inside the radiator core all cause loss of heat transfer) Also make sure that the system is full and that the electric fan and the clutch fan are operating properly. (electric fan should come on just above normal operating temp and clutch fan should not be "freewheeling" above temp either) Note: If you need to have the radiator flushed, do it separately from the engine. especially the inline 6 and 4 engines rust up inside and if the system is flushed with the radiator connected, the debris will pack up inside it and actually can worsen the condition.
there should be a small valve attached to a hose coming from the engine into the firewall this valve directs the hot engine coolant into the heater radiator in the heater box it probably is closed open it and, you should have heat then: it should be easy to find the reason it was closed
The problem with these jeeps is that the older they get the more clogged the radiator geats.
The radiator in the Cherokees are only a single row of tubes.
You can try to flush out the radiator, but replacing it with a heavy duty type is probably a better option.
Your car is not getting enough flow to cool down the engine.
Also you want to check that the electric fan is coming on. There is a coolant sensor in the radiator.
It has been too long since I did this work, but here is a tip: Go to Auto Zone, or one of those parts houses, and they will probably have a tool for this, I can't say for sure, but I believe it will be something to release the connection so it will come apart.
