My daughters jeep wont let water flow through block. over the past 2 days I have installed new radiator-water pump-thermastat plus new upper and lower lines. she let the on radiator completely fail before she opened her mouth. anything else I should look at PLEASE HELP

How do you know that the coolant isn't flowing through the block? An overheat shouldn't have caused a blockage in the motor. You might think about draining it again and flushing the block real good. Another thing might be a bad (even though its new) thermostat. I've seen brand new thermostats that refuse to open...Good luck!

no rdplz

Pull the hoses, and run some distilled water through the heater core hoses and the block itself. x2 on a new thermostat that's stuck. I've had it happen a couple times.

Double check all ur hoses, feel around the clamps for minor rips or tears hoses are cheap but can lead to some seriously messed up problems.

Yea, that's strange... it's a '99 so obvioulsy ot doesn't have that horrible closed, pressurized system my '89 has... I would double check thermo and water pump.

how hard should the upper radiator hose be when engine is running,

freegdr

hard, is it overheating,at idle or running down the road ,if it is getting hot

pwr198

no. it just doesn't seem to push water through it. I can force water through it by putting water in radiator and pulling off different hoses but if I have all on except top water pump line it barely trickles out ? Help please

freegdr

you mean the line coming from the heater core to pump??????

freegdr

this line hooked to this tube

pwr198

no water comes through that one, it doesn't come throught the one that goes to the radiator, I flushed heater core and lines but water still doesn't seem to flow through large line. even at operating temp upper rad line is hot but very sqishy.

freegdr

if the thermostat opened and its not running hot your good to go not really gonna feel water running thru the hose the small tube in the radiator are gonna slow it down for cooling purposes

so is that hose somewhat like a evaportion type hose? but also if I remove that hose No water comes through it just steam
