Core? Yes that has been. Radiator? No. manifold? Yes. Block? No. Actually maybe.

Ive got vinegar in it right now. I didn’t see any chunks when I flushed it and these could be small enough chunks to plug up each passageway too. In other news I found a temp drop in the middle. Almost 200 on the sides and top, bottom is low but that’s to be expected but I found the middle of the radiator to be cooler. About 120-150* range. I probably have a plug where it’s most vital for the coolant to flow.

My thoughts right now. I remember the core was plugged and the valve is in poor shape and no coolant was ever flowing through it. I did flush that and it probably stirred stuff up and got it into the radiator and plugged some of it. Did flush the core again and took some serious hose pressure to dislodge whatever was in there so chances are this is my issue since it gradually overheats and not almost instant. I probably either need a better one or replace the batteries as mine seems to not read “accurately” but nonetheless a goal. 13lbs is the proper pressure. Right now it’s water and whatever else is floating around. I’ll do the proper mix when this is solved. I know I’ve been able to run water in my MJ for a few years with no issue. I’ve moved to having actual coolant since then.

Those a both great spots. One thing that bothers me is removing one of those heater core hoses results in hardly any water coming out of the core which makes me wonder if any water is getting in their but I’ve felt the hoses get pretty damn hot.

That was one of the first things I checked after swapping the temp sensor. Coolant came right out. I’ve got vinegar in the radiator right now.

Ouch. 4cyl too. Rare bird.

I have a new control valve on the way. But I’m not sure it it will actually affect anything. It is pretty damn old and crusty thought but not broken apart.

Baking soda doesn’t sound like a bad idea at all. Been using that to clean stuff. Maybe I can get it hot enough to where it’ll clear stuff out. My other thought was evaporust again. I’ll have to do that. 89 MJ said to take my digital thermostat and see if there’s no temp across the radiator somewhere.

I’ll check around. I can tell you every hose is damn hot to the touch. Like hold it too long and you’ll get first degree burns. Water pump is new. Should still be new. I had the cap off last night and saw it moving coolant. Yeah mine is doing it again similar to the head gasket. And the radiator is the original one. I’m thinking about taking it out and running vinegar through it. My luck has never shown me coolant loss, just violent boiling and overheating. Never coolant loss. No, 4.2L 258.

I know it’s not MJ tech but I want eyes on this. Since this is my first 6cyl I’m now encountering issues with staying cool. At first I thought it was the thermostat. I took the old one out, tested it, it opened way later than it should have. New one in. No change. Flushed the block, manifold and core. No change. Yes it’s been burped. Replaced the radiator cap cause the rubber was basically a rock. Some change but not enough. Fan clutch locks up when it should and feels normal when engine is off. I swear I cleaned the fins out but maybe I didn’t. Water pump is new. Replaced it when I did the head gasket. And it does rotate the right direction. headgasket has been replaced. Any ideas? Did my headgasket blow again? It slowly creeps up and takes about 10 miles of driving before I’m damn near out of the green on the gauge.

No problem! Glad they’re working for ya! Those little wires love to break when removing or installing them back into the cluster.

I can tell you some posts that have hidden stuff that had some really interesting clashes. My interior paint thread had a clash between doing it right and doing it on a budget.

Lol! Bribery. Honestly, I think bringing up any negativity this forum has had isn’t for the best. Those who have been here long enough know who those were and probably would like to do the same about not saying anything. It’s one of those leave the sleeping dog lie. I’m all for letting the forum keep its reputation of a good natured place rather than one to talk smack about some who aren’t even on here anymore. I think that’s the last thing I want the Jeep/AMC community to see about us.

I remember some stuff. That’s all I’m going to say.

Ain’t that the truth man…. Lol yeah a hot commodity

I see what you’re trying to do. Haha. Sale is just on interior parts only as these things are just taking up space these days.

I’m gonna do a spring clearance sale. All small parts are free(minus shipping cost) from now until the end of April!

Welcome to the world of Wendy wastefuls we live in….

Go the whole 9 yards. Make it a luxurious MJ with GM keyless entry that I added to my XJ. Fricken love it. Definitely spoiled myself to my XJ whenever I drive my MJ.

Usually do haha. Can’t wait. Which means wife and I will need to get caught up.

I’m inclined to believe his diagnostic method, I will see for myself, this poor ZJ has been beaten on and abused. How ever, when off the pedal is rock hard and it doesn’t even have any brake fluid in the master.

Lol got a lot to catch up on. I think we’re coming in close to the latest season. It definitely is an addicting show. Like more addicting than I thought. That and faruq’s intros are pretty fun to listen to.

Lol not that game. I really remember there a show being called robotwars in the early 2000’s.

Thanks for that! I’m really hoping the booster isn’t bad but the owner said that when he plugs the line to the booster, the engine runs fine but runs rough when unplugged. So I’ve got a bit of digging on this one.

Well would you look at that. I wonder if 94 is a one year only thing. I’ll get with the owners and see if that’s the route they’d like to go. I can’t imagine there’s much difference.
