Question Need assistance please.

I have been through a few different CJ's many years ago. Its been a while since I have owned a Jeep. I recently purchased a 98 TJ with 32,000 miles on it for my primary driver. It was garage kept but due to its lack of use it has a few issues. I need some opinions.

1st- The coolant was a rust color. in the process of flushing the radiator now. What causes this? Is it a serious problem?

2nd- The heater isnt functioning very well. Its strong but not very hot.

3rd- The manifold is cracked on the down pipe closest to the motor. I will be replacing it soon. does anyone have a recommendation?

1 The antifreeze/water ratio was not correct or it was just old and needed to go...get it power flushed...worth the cost to force the sediment out of the block and radiator...

2. change thermostat...staying open...this will effect the the engines operations...the control module uses engine temp to control settings...

3. Common problem...a good aftermarket header costs about the same as an OEM new...Banks is a good pick....there are many to choose from...pick one that fits your budget...

Im thinking Ill have to get it power flushed Ive tried just running some water through it until it gets to idle temp but I cant get it to clear up.

And when you say the thermostat will effect the engines operations, how so? My main concern is I have got myself into a bad deal. I thought I had a good setup finding a 98 with 32k but Im worried that some of these issues could progress to something serious.

I'm sure all will work out. It just needs a little tlc. The engine computer can read the water temp and make adjustments as needed to keep the engine running at top effencey

the Jeep is fine...needs to be serviced...thermostat go, they are relatively cheep about $20.00 or so... The Powertrain Control Module (PCM) monsters and adjusts engine functions, spark, timing, yada, yada, yada...the engine temperature is a variable thet the PCM uses to determine the difference between start up operation/warm-up settings and normal driving conditions at the designed operating temperature...so if you are not getting to operating temp, the PCM can't control the engine settings to keep it running at it's optimum design specifications...the computer need good information...remember GIGO...Garbage in Garbage Out...in an automobile that means poor performance = more fuel is burned...

I appreciate all the help folks. Im loving the Jeep. I sold a 2004 F150 FX4. I can honestly say I dont miss it a bit when Im riding around in the Jeep. Never thought it would be so comfortable as a primary vehicle. Thanks again.

The heater should of been set to an on position so that the cor was flushed...if not talk to the person that did it...maybe the core is plugged...also chk the vacuum box on the right fender by the fire wall, under the battery tray...which controls the heater and AC vents...

Well. I replaced the thermostat and that didnt work, still no heat. So I disconnected the hoses running to the heater core and flushed it with the garden hose. Mud like clumps flushed out, the water took 5 minutes before it was clear instead of brownish yellow. And now the heat is rockin.

After the core was clear I turned my attention to the radiator. With a fair amount of water pressure it took an hour of none stop flushing before the water was clear enough for my comfort. It went from a dark brown to clear by the end of the hour. Replaced the coolant now its a perfect lime green.

I guess thats what happens when the previous owner put 10k miles on it in 10 years, and rarely did any routine maintenance(if any at all).
