This answer was rated:

2005 nissan 1.8 motor new water pump new thermo stat no water flow no heat

tims auto repair :

hi

tims auto repair :

please explain..did the heat just quit?..or did it quit after some work on the cooling system?

Customer:

its daughters car she says its been not working sense summer I guess its the head gasket

tims auto repair :

does the engine over heat?

Customer:

shes says no says the temp gage goes to mid and stays

tims auto repair :

ok,,and never needs to add coolant?

Customer:

been adding about a qt a month

tims auto repair :

i see

tims auto repair :

lets try something simple here first

tims auto repair :

lets bleed the system this way,,,just to make sure it doesnt have air in the system

tims auto repair :

1,you need to remove the radiator/reservoir cap when engine is cold


2-start the engine and let it idle


3-turn the heater on high


4-keep coolant on hand and add it as needed...some coolant may gush out with the air,so be careful


5-keep doing this until the engine is at operating tempeture,the heater is hot and the coolant in the radiator settles down


6-then install the cap

Customer:

been adding sense 2006,,,I tried that ,,it got to temp but the heater hoses are cold

tims auto repair :

ok

tims auto repair :

does it leak any coolant?

Customer:

if it does I have never found

tims auto repair :

ok

tims auto repair :

it is very posible for it to have a blown head gasket

tims auto repair :

sense it is using a little coolant

tims auto repair :

and,,you have no leak

Customer:

how does that keep it from flowing I,m not geting ant thing with cap off running

tims auto repair :

i would think the compression is equalizing the pressure,,,causing the coolant not to move to the core

Customer:

thank you

tims auto repair :

you are very welcome
