Any receipts for a radiator fan viscous coupling? It's due for replacement at your mileage if you don't find anything that says it's been replaced. If you keep driving it and overheating the motor it WILL come down to head gasket replacement. Right now you will be replacing the head gaskets in the future due to the overheats. Read the tech section and download the Rave (service manual).

A thought, first no one has mentioned anything regarding his codes, all 02 related, mainily heater circuit and 02 rich runs.
If it were mine, I would first stop driving it so you don't toast the engine. Stopping the engine when ever it gets hot is hard on the engine, always turn the heaters on full force and let the temp. idle down to normal.
So, go order 4 new 02 sensors for the codes, then spend time on the over heat issue, be it head gaskets, t/stat, plugged radiator or the 3 fans.
After that, because of the age of the vehicle, do the major service posted at the top of the section in the sticky section.
Let us know what you find.

ihscouts: no paperwork on a radiator fan viscous coupling

Disco Mike: Yes been running the heater in 95 degree weather I look on the bright side and consider it a trip to the sauna!

Will check out all you tell me. Being that it is a 96 it needs 4 sensors all to be replaced at the same time at approx $125 each correct?

Thank You everyone

Check Amazon for the 02's. NTK/NGK . Get the cooling done first cuz 02's don't work on a dead motor.

Yes, might be better to do the heating issue first, as for the 02;s, bet you can find them fo for $70 plus, just need to look around.

Thanks Everyone! The guy kept receipts so I just got off the phone with the garage that worked on it. They were great! They have actually serviced it for the past 2 owners (roughly) 6 years. Said the engine is great on it, no gasket issues. He also said it was driven so little by both it he has never even tuned it up. Taking it to a rover mechanic Thursday, But I have them flushing the radiator today. No driving for me

Ok then mechanic believes Over Heating is due to the PO putting a 2x2 ft piece of cardboard in front of the radiator, no overheat or temp rise on test drive once removed. 2Morrow we tackle the sensors!

Thanks everyone

mechanic said a lot of old timers around here think it keeps the rad from freezing in the winter and makes the car heat up faster...guess he has seen it before
