The car would overheat then steam would poor out of the a/c vents.

 

heating core leaking maybe? any wetness under the dash on passenger side?

 

Heater core is exactly what it is. What year of rover do you have?

 

Ditto

 

Yep its the heater core... darn. So how do I fix it? Is their a diagram online that I can follow? How would I get to the heater core?

 

Download the Rave manual online, get a lot of beer, and kiss your weekend goodbye I wouldn't call it hard but it is very tedious and time consuming. A lot of stuff has to come off to get access. I haven't done it on the Range but I did it on the Disco, but I imagine it is similar.

 

any other tips???

 

The car would overheat then steam would poor out of the a/c vents. I've change the cap, thermostat still overheated. The fans in front of the radiator don't work either. Now when I put it on reverse the engine turns off
