1. WHAT IS THE NORMAL OPERATING TMPERATURE FOR MY 93 MARK VIII?

2. I'M STARTING TO OVERHEAT, IVE REPLACED THE T/S, RADIATOR,WATER PUMP, AND THE SENSOR FOR THE GAUGE, STILL TO NO AVAIL, I TOOK AN INFARED THERMOMETER AND AT THE WATER PUMP READS 204 DEGREES WHEN THE GAUGE NEEDLE IS AT THE "O", IS THIS ATTRIBUTED TO A BAD T/S, OR AM I NOT BURPING RIGHT?

3. WHY THE HELL IS IT OVERHEATING WHILE DRIVING, BUT COOLS DOWN AT IDLE, I THOUGHT THAT WAS WEIRD.

ANY HELP WOULD BE GREAT, I LOVE MY CAR, AND DONT WANNA GET RID OF IT, I GOT 64,000 MILES, WTF MAN, WTF......................:shifty:


WHAT I DID WAS FILLED AT THE XOVER TUBE TILL THE BOTTLE WAS FULL, THEN LEFT THE PLUG OPEN AND RAN THE MOTER FOR ABOUT TEN MINUTES, WAITED UNTIL I SAW NO BUBBLES, FILLED AND CAPPED IT OFF, IS THERE A POSSIBILITY THAT THERE IS STILL AIR? ANY ADVICE WILL KEEP ME FROM A SMALL MODIFICATION TO THE ENGINE BLOCK INVOLVING C-4, THX
 
"c4" thats a little extreme...and expensive...just hold the gas pedel down in park till you hear a boom...and some smoke...might save you money...but +2 how are you getting the air out of the system...or are you just adding and not letting it out?...
 
Please dont edit your post, add to the thread. Makes me look like I did not read it.... :p

Anyway, why not open the cap at the crossover again to check? Seems pretty simple to me! There is a VERY good chance there is still air in there.

Other possibility is an oil-filter adapter gasket leak which some have reported can let air into the cooling system.
 
Preash

well, what I've been doing is letting the car run with the overflow cap closed and the xover tube open, and i add fluid until it doesn't bubble, at least i figure it doesnt bubble anymore, yesterday, i opened up the xover tube plug and rocked the car back and forth with the engine off, and it bubbled up some, then i topped it off and drove about 30 min. The needle sat at the "o" still, and rose slightly from there, I still need to pressure test, but thats gonna be a little bit away, this problem has broke me.
 
Well it sounds like either a bad pump, which I know you said is new, or a bad t-stat, which you also said is new. Happen to put the t-stat in upside down?

On the other hand, what year? If its 96 and older there are two sensors for temp. The one on the driver's side, I think, is the gauge. It has just one wire coming off of it and is a push-on-stud type. The other is a plug type, thats what the ECU uses for info.
 
Its A 93, Anybody Know Where I Can Get A Pictured Diagram Of The The T/s Housing? It Is Possible That I Put It Back In Upside Down, Would The Coolant Still Flow Through The Tube On Top If Thats The Case?
 
You shouldn't see coolant flow until the thermostat's open, so.. .

Unity's real good on advice, I'd say make sure you have all the air out before anything. Believe me, it's a pain sometimes to get all the air out. One time, I bled it out on day 1, didn't get it all out. Drove to work the next day running the defrost to keep the cooling fan going. Bled it that night, still didn't get it all out. The third night It finally burped for the last time and I was good until I replaced the radiator and had to bleed it again. My old radiator was dirty though, I think that doubled my troubles.

And, the first time, I kept posting on the board pissed off thinking no way was there still air in it. but, everybody was right. These cars have a few 'different' things about them.
 
Yeah, That What I'll Try Next, Anyone Know Where I Can Get A Picture Diagram Of What My T/s Looks Like In The Compartment, So I Can Tell Before Pulling It, Its A Real Pain For Me Do Get To.
 
Okay, So I Burped Again, Then Drove To Work The Next Day, The Car Did Maintain Normal Temp. For A Little Longer Than Before, So I Figured I Must Be Seeping Air In From Somewhere, After Inspecting The Thermostat Housing, Which Can't Be Out In Upside Down, Btw, I Noticed That The Bottom Hose Had A Trail Underneath, My F*&^in Mechanic Didn't Put The Hose On All The Way!!!!!!!!!!!!!!!!

I Just Drove It Back To Him, And Pushed The Hose Up Myself On His Rack! That Was Funny To Me. Anyway, I Then Popped The Filler Cap Open Again, Rocked The Car A Little And It Bublled A Little, I Filled And Drove Back To Work, It Still Does The Same Thing, Now At 45-50 Mph, It Stays In-between The "n" And The "o". It Stays There, But I Only Drove About 5 Miles On City Streets. I'm Fairly Sure It Still Needs More Burping, So I'm Gonna Continue To Cross My Fingers,

What Are The Odds Of The Lower Thermostat Housing Hose Seeping In Air?
 
The housing can seep air in if the o-ring was not seated right, but its pretty easy to get right.

I would burp again and see. Then you may also want to consider doing the oil filer adapter gasket.

The adapter is were the oil filter attaches to, but as you can see coolant also goes through it. The original gaskets are a VERY well know weak point. Usually one leaks oil from there, but there have been cases of air getting in as the cooling system cool, so you may not see much if any coolant coming out.

But if you keep burping, coolant is going out somewhere - leaking or as evaporated steam.
 
Okay, I'll Go And Get A Gasket For That And Just Go Ahead And Do It, At This Point, I Doubt I Damaged Anything Crucial On My Engine, It's Just Driving Me Crrazy.
 
Also, The Pass Side Temp Sensor(the One For The Computer)could That Mess With The Gauge?, Oh, And Can't I Just Leave The Fill Tube Cap Off Like While At Work And Have It Burp?
 
No, the two sensors are separate.

You could leave the cap off, but it wont help really. It wont help air get up to that point.
 
Okay, So I've Heard That My 93 Has A Continuous Flow Heating System Or Something Like That, Making It Where Turning The Heat On Doesn't Affect Anything Really, However, When I Tun My Heat On, It Stays Cooler Then Not? So Now Im Confused.
 
Well turning on the heat blows air past the hot heater core, so yes it will cool the car. But the continuous flow means the core is always hot - well once the coolant is. There is not valve that cuts flow to the core when heat is off.
 
So Before I Go Outside And Scream For Not Checking This, Could A Leaky Heater Hose On My Car Cause My Problem?
 
Yes because as the system cool, it would draw in air. Then when it heats up it can push coolant out.
