Overheating (only in summer) already burped it.
- Thread starter Myco

I would think it would cause more problems, some of the "stuff" it would remove may cause leaks.
That backflow kit was a bit hard to handle with this car.
It still overheated. So, what's next? You got it. Radiator. Got one. A good one. And put it in today. No dice.
The problem overall is getting better. While at first it would overheat within 5-10 miles like I said. Now though, I can sit in 90degree weather, in traffic, for 15 minutes and it doesn't overheat (rules out fan... it does work though I checked it.)
Before I go further let me tell you what the temperature is doing right now. When the problem started it was going up then down like it needed burping. Tonight (after installing the radiator and running it, letting it cool and then burping it.) I drove 15 miles on a hot engine around local streets. No problems. I jumped on the freeway and after 5 miles the temp jumped up to halfway between the middle line (where the temp is normally) and the line above it. Then it jumped up to touching the line above it's normal position. I jumped off the freeway and decided I was just going to drive it and see if the temp levels off. It did... before I got to the first light it had leveled off. I then drove it another 5 miles and decided to get a bite to eat(still normal). When I stopped to make a u-turn the temp went up slightly and back down, and then in the middle of the u-turn it did it again. Just like it needs burping???
I'm hoping that I just haven't burped it correctly so let me tell you what I've done. I've jacked it up and put it on stands and burped it after it cooled overnight. I've burped it for 30 minutes. I've squeezed the tubes ad nausium while burping it.
What I'll do next is try to find some type of litmus test to see if there are exhaust gases in the coolant. (as it's been flushed twice there should be none) (need to know where to find one of these tests) If I can't find one of those I'll get a compression test done.
The car is not loosing any coolant. The coolant is not overflowing the reservoir. There are no particulars in the coolant. The old radiator looked pretty good. I haven't changed the reservoir cap but at this point I don't know if that will do any good.
While there is no indication that the head-gasket is blown I'm suspecting it is. I'm getting horrible gas milage (and frankly I always have and I don't feel like this car has as much pep as it should.)
I've read that the burping procedure is an art and I believe it now. I heard that taking the crossover cap off and the reservoir cap off overnight and then burping is one way to burp. Any advice.
Thanks for reading the long post guys. Appreciate it.
btw. 97 Mark VIII with (I believe 105k miles on it) It's supppose to be the 2nd engine replaced under warrenty be the previous owner though I didn't get any documentation on it.

New Radiator. Sorry, must have edited that part out.
Brand new high-end I might add. Radiator.
(* I didn't put the above in red b/c of anger but to show others that it has a new radiator.
Just wanted to be clear about that. )I'm getting the kit. If that doesn't do it. I guess I'll do what your talking aobut.

I would find the problem affecting performance and mileage. It's my guess that whatever it is, is also causing the overheating.
Do you have a chip?
My '93 runs hotter on the highway on the dyno tune or race tune.
I don't know if it's relevant but I used to have an older Ford that had overheating issues. Tired of messing with it, I sold it only to find out later the timing was turned up too much.

I have noticed the same. With elevated engine temps, performance is cut back.

What came first, the chicken or the egg?
He needs to determine if performance is a problem, before the temps rise, or if it's only a problem as it starts overheating. It sounds like he's just about replaced the entire cooling system, except the water pump, which leads me to believe that there's some underlying problem causing the overheating.
But, it's all speculation, hard to diagnose a patient that you haven't seen :frown:
No, I don't have a chip BUT. When I got the car I did flash it to a 98 ECU using an x-cal. (not mine)
Maybe that's the issue? I thought there were no issues with doing this. Maybe I was wrong.
edit: Also, I just thought about this. I flashed the ECU with a 98 Mark but it wasn't an LSC and my mark is an LSC model.

Flash it back to stock and see if it's different.
You sure it was an SCT (X-cal) and not the old SuperChips flash tuner?
I don't think LSC vs. base matters if the PCM strategy code is the same. If the PCM code didn't match it's hard to tell what you may have going on.
Just to update the thread. After burping it one last time it hasn't overheated for over a week. I've driven in 90+ degree traffic for over an hour and and over 10miles on the freeway.
Last night I got under the hood to see if it was loosing coolant. Just checking right? Everything looked fine but as I started closing the hood I saw something shinny on the bottom of the engine block in front. Thought it was odd so I got the light and stuck it down there and started looking around. Under my water pump, where there wasn't one before, was a big giant green line where it is leaking. I've looked before but never saw anything. I'm guessing it was evaporating quickly or the fan was blowing the coolant away. Anyway, I've bought a new water pump and that should be the end of my woes.
Thanks for all the help guys.

I'm an expert now.
FYI:
Just so the people on this forum know. The proper way to burp your car goes like this:
1. Jack front of the car up and put it on stands.
2. Fill overflow tank to just above the cold level.
3. Take off crossover cap. (duh)
4. Take funnel from oriellys. NOTE: This is the small funnel with the inch to inch and half long nipple at the end. It's only a couple bucks. It has a wide top and I would guess only about 7 inches in lenght. Take the funnel and using a hacksaw (saw of any type) saw off the bottom half of the nipple. This allows you to literally SCREW the funnel into the crossover hole.
5. Fill crossover to halfway up the funnel.
6. Run car for 30 minutes regularly squeezing the radiator hose on the left side.
7. Shut off car.
8. Let cool.
9. Repeat. BUT. Start the car THEN open th crossover and screw in your funnel. Fill up like before but only for a couple minutes.
10. If still showing signs like an air bubble. . Repeat. BUT. Start the car and let car get hot. Shut off car. loosen overflow cap to releave pressure *(make sure when you squeeze the top left hose you see the fluid in the overflow tank go up and down. Then tighten the overflow cap. Take off crossover (if any fluid comes out retighten.. your done.) refill crossover. DONE.
DONE.... your system is properly burped.
