hi can any one help?
put a new waterpump onto my 97 2.5 turbo diesel cherokee. drove it for about 10 minutes then the low coolant warning light came on but the temp stayed normal. got more coolant and toped up but it didn't take much. then i gave the hoses a few squeezes and got a few bubbles out. then did a good bit of driving, the light stayed on but the temp didn't rise. got home went to top up again but it was full.
oh yea funny thing is the low coolant warnig light didn't come on when the pump died and i lost my coolant?? light still on??????????

 

coolan level sensor in over flo bottle sticking?????

 

mine stays on too but only after i put a 93 head on my 95.. im assuming its because the sensors are sh!tting a brick but i am curious to see what happens with yours.

 

most bottles have a similar sensor to this the connections corroded or stuck down

 

Yep. Pull it out and clean the connections.

 

right guys sounds like the coolant sensor sticking alright. will have a look
thanks for replys.

 

oh yea mine has this type of bottle, where's the sensor on this?
