Jeep troubles

<< < (2/4) > >>

Tsalagi:
Thanks for the info! I didn't know any of this. Odd thing, a few days before the head gasket blew, the heater quit working. I'd almost swear the two things are related somehow, but can't put my finger on it. The radiator was full of rust, which is strange as I just had the radiator and water pump replaced last year.

sailordad:
tsalagi, you say the heater quit working.does that mean the fan or nor heat coming from it?
if it was no heat,that was probably caused by loss of coolant due to the head gasket leaking it.
when the coolant leaks out the system fills with air,its hard to keep air hot enough to use for the heater,you blow air across a heater core thats
full of air and it cools off almost instantaneously.them jeeps are known for bad heads/gaskets.not to mention intake/exhaust  manifolds that like to warp and
t-case out put shaft seals that like to leak and whel bearings and other things.
the rust comes from using straight water in the cooling system.it doesnt matter if you had the radiator adn coolant pumps replaced or not.water in the engine block doesnt take long to create rust.rust is a by product of heating water in a metal.heating water in metal actually causes rust faster tahn just leaving water sit in metal without heating it.i as a professional automotive technician would never ever recomend using straight water in an engine cooling system.always use a 50/50 mix of good   quality anti-freeze with water.never pour coolant in the radiator and then add water,always mix it prior to putting in the system,if its done the other way it may never mix properly.the rad kit that i mentioned before,is a device that hooks up to the fill neck on the radiator.then you attach an air hose to it and creat a "vacuum" in the cooling system.this vacuum will be great enough to collapse all radiator and heater hoses.this process removes any and all air (if done properly) from the cooling system.
once 26" of mercury have been achieved(vacuum) let it sit for atleast 1 mins.thie should pull any air that may be trapped in the system,if it does not hold this vacuum then there are leaks somewhere in the cooling system and that will ingest air back into the system.air in the system is bad and can actually cause a "hot pocket" of steam that can cause internal damage to the system.if the system is holding vacuum then its time to use the "rad kit" to fill the system.i have used this device and love it.
i do alot of cooling sysetm/ac work nad swear by this tool,as a matter of fact FORD does not recomend filling a modern cooling system any other way.

good luck

Tsalagi:
Thanks for the great information, Sailordad. I appreciate it it a lot. The heater blows, but doesn't put out heat. And did that after the head gasket was replaced, too. Oddly enough, when it redlined, I turned on the heater full blast to try anything to vent the heat and the needle climbed away from red. Really weird. But it still vented from the escape port on the reserve coolant tank.

This jeep has me scared now. But the information you gave helps me a lot.

sailordad:
the heads on them like to crack externaly
very carefully inspect fot a white residue or what looks like calcium build up around the edges of the head in areas
near the bolts for the intake/exhaust manifolds etc.

if it was doing that right after you had the head gasket replaced,then they didnt either fix it properly or get the air out of it.
them things are touchy to get all the air out,kinda like the old ford rangers were

good luck

Tsalagi:
Thanks for the help, everyone. The jeep appears to be good to go now---cross fingers, knock wood, and everything.
