reaches the middle of the C---H or never gets up to the middle?

is it overheating? check with a 15 dollar thermo-spot gun various parts of the radiator to find any blockages....change the coolant if it's smudgy and full of crumbles~

okay the thermostat is defective---jammed open~ return this one for defective...make a pot of tea and plunge this one in....it should open....pull it out...it has to close...or it's a baddie....they happen, y'know~


after checking or replacing thermostat knowing its good and still no heat what would be your next suggestion have allready drained & flushed radiator fluid.

yessir, de-ionized water (no electric laden ions) and glycol 50/50 mix~ pre- mixed are cheaper and more convenient~ be sure to capture the old coolant for recycling at your auto parts store...they've got a machine for doing this~

birds like the sweet taste....then die, so in the interest of saving a few little lives...please do~ or take it to a shop where they are prepared to deal with this responsibly~

Best Answer

the only other thing might be a corroded water pump to where the fins are met with destruction and do not pump an coolant reliably~

try to flush the heater core with a water hose. take your inlet and outlet hose off and put the water hose in the outlet reversing the flow until it flows out and it clears up. worked when I did it on my cousins car. had the same problem and has great heat now. hope it helps
