I just bought a 97 Discovery 1 and it overheated today and when I got out the expansion tank had sprung a leak. I'm hoping i didn't ruin the engine as the red light came on despite the dash needle staying at 8 o'clock. My question is this, my local Pik n pull has a 96 & 99 Discovery 1 would like to know if I can use either model years and pull one from them. Obviously, if it looks like the same one I can use it but just want to confirm that one of them will work. I will replace my thermostat just in case (using the 180) that I've seen posted here in the forum. Any chance that I did serious damage? I only drove less than a mile once the light came on and I drove with the heat on HI. I still had fluid in but I had lost a fair amount. thank you.

 

If the 99 is a D1 you are good on both. Avoid the black tanks as they are prone to failure. The white ones are the ticket. If you are interested I have a white one for sale. PM me for details.

 

got the one from the junkyard and it's the white one. Holds pressure and hasn't overheated yet. Thanks for the help.

 

good deal. Just dont fool with the black ones.
