Engine shuts off while driving! Jeep 97 4.0L

Hello all! I'm in a tricky situation with my JEEP and I don't know what to do.

Basically, I had removed my engine fan about a year ago. The fan mounting was busted and the fan blades were scraping against the belt. So I took it out. Drove all through summer without it. No overheating. No problems.

Just recently, I was noticing that my JEEP would idle really rough. This occurred for about two weeks. Then, lo and behold, I'm idling in a drive thru (I was hungry!) when suddenly, white smoke/steam begins to billow out of the front, and coolant begins to pool below.

I get out of line, and drive down the street (two blocks) to a local shop. On the way into the driveway, the engine shuts off. I crank the crap out of it and floor the accelerator, and after about a minute the engine turns over enough for me to drive it and park it.

The next morning the mechanic tells me he needs 800 to fix a leak in the radiator, and fix the water pump. I knew the water pump was leaking before. Oh, and he also wants $250 for a new engine fan - which I can buy online for about $55.

He also admits that he can't tell if a head gasket is blown until he does the first set of repairs. Hmm...

I let the car sit about a week. Then one night I walk down to the shop to drive it home (about 2 miles). It starts up right away. Super good to me. I ride it pretty hard, I did notice the temperature gauge stayed at 0 the entire time. Then as I'm turning onto my street, it dies again.

Same thing. I crank the hell out of it, floor the accelerator, and after about a minute it starts up again.

I just started the car again to see what is happening. No big leaks of coolant. I didn't drive it anywhere, but it started fine and everything seemed okay. The only thing was the the temperature gauge stayed at 0 again.

Any thoughts?

I'd like to sell the car eventually. I need to get a smog check first. I contacted some junk sellers and they gave junk prices and alerted my junk-dead-beat senses. So I want to sell it cheap to another owner.

JEEP 97 Cherokee SE 4.0L 175K miles

Thanks for your help!

Did the engine seem like it stalled because of an electrical issue, or do you think it stalled because it overheated and seized up ? If the engine seized, it is probably damaged internally and needs to be replaced. The mechanic is a thief and you should never deal with him again.

Thanks for the reply. To answer your question, I'm not really sure. However, it doesn't make sense to me that an engine would overheat while 1) coolant levels are full, and 2) the car was moving about 40mph, so the missing engine fan isn't relevant there. Am I on the right path with my thinking? Or no?

If it is electronic, what could it be?

Thanks!

To me, that is related to/caused by overheating. The faster you drive the more heat is generated within the engine.

Yes. I agree. But the engine cut out on two separate occasions when I was driving it. Shouldn't there be enough wind/air flow to cool the engine while it's gong 40mph?

No not much air gets in there the condenser and rad block the grill and hot air rises. So it's all chilling up under your good with no air movement

That not how the cooling system works.

You need to find and honest and competent mechanic. Explain to him what happened. If he agrees to look at your Jeep, have it towed to his shop for a proper diagnostic inspection. Seizing the engine due to overheating can cause internal damage. The head will need to be removed and inspected at the bare minimum.

The temperature gauge never moved at all. When I was overheating in the drive-thru line, the temp gauge was normal (in the middle). When the car engine stopped, both times the gauge was at 0 - far left. When I started the car yesterday, the temp gauge stayed to the far left as well. It appears as though it's unresponsive.

It would if it were over-heating, wouldn't it?

What, may I ask, led you to this conclusion?

$800 for a radiator and water pump and $250 for a new fan is thievery. $1100 minus $180 in parts and about 4 hours of labor = $230 per hour for labor.

New radiator $80
New water pump $50
new e-fan $50
