Did you ever get this resolved?

Nothing yet. I’ve tried everything. New head gasket , block head is good , water pump fan clutch thermostat fan cover radiator pipes , radiator - 3 electric fans , 1 mechanical. Everything I swear and nothing’s happening. I have no idea what to do! I really am depressed and seems like this forum is old so no one is paying attention to it anymore. I’m thinking of changing the exhaust couldncause over heat.
& ive realized the car over heats mostly when ac is on.

Interesting, I've found this forum to be vastly superior to others. I've posted questions and gotten zero responses on other forums, or if I did it was 1 person after long hours or days of waiting. Maybe you mean this thread? If so it's because the last thing you said was that you'll update us.

If the overheating is happening when the A/C is on, do you notice if the original e-fan (the one behind the radiator on the driver's side) is kicking on? Did you check the oil for coolant? A 2000+ acting as yours is with all the items you mentioned screams cracked head. Have you considered a lab analysis of the oil if you can't get the testing tools? (You might consider buying them online if that's an option... I don't know anything about Dubai, but if you're on here at least it means you have internet.)

Oh yeah, she has the internet, but shipping could be a problem. I was once conversing with a guy in Russia who needed an motor for the electric fan and had to pay around $300 to get it delivered due to corruption in the delivery chain! Everybody wanted a piece! I also know a Cuban who needed clutches for a GM automatic transmission and had to get them delivered to a friend of his in Panama who had to ship them to him in Cuba because the US doesn't deal with Cuba!

IDK her situation, but if she knows anybody in the military, maybe she can get a head shipped FOB MATS. (Freight On Board, Military Air Transport Service)

Will a 0630 head from a 1999 work on 2000-2001?

It will bolt to the block. It might not be completely compatible with the intake/exhaust ports designed for the 0331 head however.

Does your lower radiator hose have a spring in it? Mine didnt and was collapsing, causing mine to overheat. Not sure if that is your situation, but just a thought.

Thank you!

Okay so guys , after I’ve gone to 100 mechanics and no one has found out what the reason is , yesterday someone told me that the car is American specs and the engine is built to keep heat in the engine ‘ harsh cold weathers ‘ so you could use the car anything after it goes off. ** which we really don’t need in dubai as I’ve said temp here is around 50*c

He told me there is a part or something like that , that keeps the heat in the car and if removed the car would be normal and not over heat. Anyone has any idea what that is??

Obviously there' s an issue...but the outside ambient temp of 50*c certainly doesn't help...that's quite toasty. That would be rough for a lot of vehicles. I used to live in Australia where summers were usually 40+

I don't know if this is a Mr. Obvious question that you've already checked or not...but have you checked your oil to see if it appears normal or looks more like a milkshake? That would tell you straight off as Cruizer mentioned... getting coolant in the oil from a cracked head. Of which the 0331's where well known for.

I think we are now going in circles...

Have any of these 100 mechanics or you yourself done any diagnostic testing? If they/you have not then that is the only option to start with. This issue will not fix itself.

He probably means to take out the thermostat. The most common way they fail is to stick in the closed position which does not allow the coolant to circulate. An old school trick is to just remove it, but, that is really a bad way to do it, the best thing is to just replace it if you suspect it is not opening properly.
