I have a 2002 discovery thermostat housing started leaking/ over heating replaced thermostat. temp gauge light is on and needle stays on the bottom. how do i get the light to go out will my gauge work then?
lower radiator hose is cool heater blows cool with maybe warm when i first turn it on turns cool. blead my system little bleeder screw upper radiator hose at t. stuck a water hose in tank til water came out of bleeder hole.
let engine run turned off cracked bleeder screw a little see if maybe air would come out some did not much. seams water pump is pumping have a stream flowing at bottle neck with cap removed no oil in water no white smoke. this is my first rover. please help
thank you. Larry

 

have you lossened the reserve bottle and elevated it?

 

no i havent think that might help get the air out? i will give it a shot
thank You

 

elevate the front of the truck 6 or so inches if possible, release the cooling resevior and elevate that also. remove the bleed screw, turn on the heater and slowly fill the resevoir to the top until coolant start to come out of the bleeder screw. You should check it in a few days you may have do go threw the process again. if this does not work get back

 

ok drove up on some ramps opend bleader screw ran heater with engine on and off still wont get hot lower hose still cool held up coolant tank.
gauge still on bottom gauge light still on. whats next?

 

check your mail I sent PM

 

feel free to jump in here anyone.
"ok did that my temp gauge now works still cold air"
he now has a working temp. gauge but still has air in the system.

 

Ok found out top hoses were switched ya i know corrected that bled system still
bottom hose is cool and no heater

 

It is amazing how many D2 owners don't have a clue on how to bleed the coolant system.
First you only bleed the system with the engine being stone cold and not running, open the bleed screw and fill the coolant bottle til you get a steady stream of coolant, the replace the bleed screw, replace the cap, start the engine, turn on both heaters and let it run for a bit at idle. When at operating temp, with the engine at idle, you should have some heat coming from the heater, if not you repeat the process again.
The next 2 mornings, you fill the coolant bottle to the lid, not the line, if it then doesn't continue to drop you are OK, if it drops, then it is time for a pressure test and possible chemical block test to rule out a head gasket.

 

mike we really do know how do bleed the system but we are having soo much fun imagining you all refaced for having to write the same thing for the 100 millionth time... hahahhaha! oh did you ever hear from your engineer friend about the top hose staying sucked dry..
