high temperature warning light goes on more and more often when Im going up on hill.. the light its not flashing its just staying on until I slow down. I know when its flashing then its related to water pump but in this case its staying on and after that when I open the antifreeze reservoir its not a lot of pressure there. But while I'm driving I can hear how the antifreeze its pouring or traveling through in front of me under dashboard and usually the high temp warning light comes on after a specific sound of pouring antifreeze..and this can mean a few things; thermostat? I don't think so. I did try to get the air out from cooling system if there was any but I think there is another problem and like I said only the high temp warning light goes on and nothing else, The engine was replaced and has around 33000 miles Anyone has any ideas why ? Thank you
Maybe it's telling you the car is overheating? Did you check the coolant level? Check for codes to point you to the direction of the problem?
Welcome to Prius Chat . How many miles since the replacement engine was put in? How many miles on the car? What caused the engine replacement? Was a new water pump installed with the replacement engine? Keep us posted .
The car itself has close to 400.000 The engine was replaced because of head-gasket but before replacement I tried to put 'BLUE DEVIL' .. on the cooling system in the hope that will fix the head gasket problem.. and worked for only 1 day after that I changed the water pump because got stuck inside (it looked like swollen inside) and we think that blue devil sh...t did this. After that I replaced the engine (a good one) and drove it for about 23000 miles until now ,
