Ticking can come from so many places I could write all day... Use a screwdriver or a long extension as a stethoscope and try to isolate the source. Best guess I can make without seeing/hearing it is either you cracked an exhaust manifold or a valve lifter is sticking (only a guess) If it's a lifter, you can add a quart of marvel oil and usually it will quiet down.

Overheated. Why won't it start?


I'm not really familiar with JEEP mechanics but if you've replaced your water pump and it's still overheating with full water/coolant level, you should check the thermostat; when it fails, it's a common cause or overheating in all kind of cars

Car started knocking really bad got a cylinder 2 misfire code after opening coolant bleed valve with enging hot


Okay, it may be due to overheating, that may be the noise you heard, lets hope. first allow engine to cool, open radiator cap or the resivoir cap, which ever is the fill, remove the bleeder at top hose and fill radiator slowly until coolant comes out bleeder.

note if water pump was replaced due to leaking and engine was overheated at that time then it may be a good idea to replace the thermostat .
after filling is done start engine and allow it to run. watch temperature if temp start to climb past half way shut engine down and let sit for 5min. then restart and check level, in res do not open cap . feel air from fan and see if it is getting hot, this may take up to a half hour but do not drive,

A few questions, does this jeep have an electric fan?
when you heard the knocking was engine temp hot?
If you start jeep cold does engine knock?
Did this jeep get a new thermostat with waterpump job?
did it overheat when pump went bad and why did water pump get replaced?

sorry for all the questions ,just trying to get all the info to help you .

2004 Jeep Grand Cherokee Special Edition overheats, change radiator 5 times


sounds like you should check your thermostat,head gskts. water pump. If it' overheated that many times you are probably looking at resurfacing heads if they are still good, and replacing head gaskets and waterpump etc, might be easier swapping egj. out

I have a 2000 jeep grand cherokee and its just started overheating after the fan broke, we replaced it then replaced the fan switch relay but not sure what else it could be.


you also have a thermostat that mounts in one of the pipes at the top of the engine and there is also a temperature sensor the other problem is you could have a bad water pump lift your hood and see if there is any rust or liquid coming out of the water pump where the pulley is if the pump dosent circulate water you could over heat

Overheating while Eating


Bad themostat, dirty radiator (the front of it), corroded interior core of the radiator, weakening water pump, bad radiator fan.....just to name a few. More than likely? Low antifreeze level, or the thermostat.

If you put the thermostat in correctly (spring towards the engine) that should be OK. Likely if the water pump wasn't leaking or had a bad bearing, you wasted your $ on that.
If you re-filled it and did not have the heater on high heat, you may have some trapped air in there. But, still overheating says another thing. If you have a blown head gasket, it can pump compression into the cooling system and drive the coolant from the core. It will also overheat. You can have that tested at most any decent shop that will do a hydrocarbon test to find that.I think someone makes a chemical test kit for that but not sure if it's very expensive or not. White smoke from tailpipe will also be an indicator as will be any coolant in the engine oil or coolant on one or more spark plugs. If it turns out that it has a head gasket problem don't stop looking for problems as often a faulty fan or obstructed radiator can cause the initial overheat that caused the gasket to fail.

My jeep grand cherokee started overheating at idle


try the water pump - first - make sure the radiator is really full - take the cap off cold and fill - if it looks full - start and run 8 minutes or so - then fill it up - look at ur fan belt - is it tight - tight is about how much pressure u use to make a firm hand shake with little movement - any movement over about an inch is loose - when the jeep warms up the belt can slip and not even make a noise - - new materials don't always squeal. - then be sure ur water pump is ok - they go slowing - the fins wear down - one more thing is the radiator - u don't say how many miles or what maintenance schedules you have or not so that's it for now

With the water pump removed, you have to heat the body of the water pump. There is a O-Ring that seizes the tube into the water pump. Sometimes you can just loosen the bolt and heat the pump with it still bolted up the engine. Use some pliers to wiggle the tube while pulling the tube. When you put it back together replace the o-ring and add some rtv sealant around the o-ring too. This helps the seizing problem. Hope this helps
