Cooling problem revisited
 

Well I still have not fixed the cooling problem. In traffic today (without the a/c on) the car overheated. In fact it got to 250 before I could shut it off. So far I have bought the 3 core radiator (Godan from PepBoys), a Black Magic fan (got rid of the crappy flex fan), and changed the t-stat to a 160. I talked to a guy at the Radiator shop who said that he believed that I wasnt getting enough air flow. I also told him that I might have a standard rotation pump, which I will find out about tomorrow.

My question is which upgrade should I perform next, or try the last two at the same time:
1. Griffin 31X19 , 1" core radiator
2. a secondary pusher fan (gonna have to trim alot of material off the headlight mounting panel.

get rid of that 160 stat!

with a 160, it is open all the time and never allows the coolant to stay in the radiator long enough to cool, eventually the coolant becomes heat saturated and overheats, common with Florida STANGERS.

Did the radiator guy do a pressure check on the radiator and cap? Sometimes the cap doesn't seal and the radiator doesn't pressurize causing over-heating problems

No, no pressure test. The cap is only a year old, it was bought at the same time as the radiator. It is one of the Stant Levervents, so I might also get rid of it and get a regular cap.

What kind of temp gauge are you using?

Does it ever overflow into the puke tank?

Move up to a new 18 pound radiator cap and replace the t-stat with a 180, or even a 192. Stant levervent caps are usually good, and are what I would recommend, but Stant t-stats suck eggs, and should be avoided at all costs. I recommend an OEM Ford t-stat, as it's one of the only ones available that has a built in bypass that permits "burping" of air pockets.

Take care,

Using an Autometer Phantom gauge.

I replaced the cap today with a regular cap to test it and it didn't change anything.

I also replaced the wter pump with a 93 model pump instead of the 84 Corwn Victoria pump. This way I can try a stock fan and clutch set-up. Hopefully my friend didn't get rid of my old fan and clutch.

I'm having the same problem, it heats up to around the middle and I have a 160 thermostat. Im running a 700 CFM double pumper, mechanical secondary carb, fully ported dart seniors, shaved over 50 thousandths. 1 3/4" long tubes, victor jr intake and more. I have my 190 thermostat. Should I put it back in?

Go back to a 180 degree thermostat... its the 160's that are killing all you guys....

i have a 95 with a brand new water pump, brand new radiator,and a 192 thermostat, and my car overheats in city driving only, when im on the highway it stays at the o in nOrmal. any suggestions

I have 160 in my car and I have NEVER Got over 170 every..... I can put my hand on the Radator righht after i Have drove it and its not even to Hot...That Said I live in Michagan not to hot...Most of the time...... I do use the stock Gauge But I have a new temp sender and it never get Past the frist Mark...

Yea with my 160 stat it ran cool, probaly too cool, just put in a 180 the other day because the 160 wasnt warming up enough, causing bad idle, now it runs fine, most people i know with carbed cars run 'without' a stat, and it runs like 170, at least thats what this dude down the street told me his does.

So you have a BM fan? the BM flex-a-lite works well with me, and i live in south tx, which is hotter than florida sometimes.

I figured the BM would be fine, but it has not trned out to be. Now that I have a waterpump made for a Mustang, I can try the stock fan and clutch as opposed to the BM or the Flex and see what that does. I am also thinking of changing the t-stat, but want a good one.

I have the flexalite fan made specially for the 5.0, it pulls more air then any other flexalite's i know of, i guess the clutch fan is worth a try, but i've had bad luck with them, just the durability of them, i like to have as less drag on the motor as possible, but i do alot of racing.

hope it works.

btw, i have a 'stant' t-stat, i guess thats the chepo t-stat, but it seems to be working fine.

I tested three Stant t-stats and every one was so inconsistent that I would never use another one again. The first 180 that I tried opend at five different temps. It would never open at 180, more like 190, 200, 195, etc.

Now I have the stock fan and heavy duty fan clutch. I ran for about 35 minutes with the a/c on and it got to 210. After sitting idle for about ten minutes more the temp started to go higher. Not very fast but it started to climb. Now what?
