If your radiator has blockage it will cause it to heat up. You can still see circulation but if the bottom half has blockage it will cause this also. Also the water pump could be going and not working the way it should. I would try these things and then see. That way everything was done.
I had a 73 Ranchero which started heating up to that point and once I changed the radiator it stopped and started running cool again. I would replace those last two components.

I would definitely do that. I pulled my hair out because I seen the radiator circulating and thought it was OK. In turn I replaced a bunch of stuff not needed also but look at it this way you know everything is done now and will probably last you a good long time. Let us know how you make out.

Ok, the radiator didn't do it, but I did have an idea that I wanted to run by you guys. It's got BBK shorties on it, but it has a bad exhaust leak on the passenger side at the collector, could the heat coming from the leak cause the heat build up in the engine compartment. And if so would it cause it to over heat?.......My head's about to explode and I've got a rash from scratching my head.......

I'm coming in late here and it appears you look at all the usual stuff like thermostat and fan clutch. So let's find out if you are running the stock cat converters? You haven't posted what year you car is? If you did I may have missed it? I'm not sure but if your thinking an exhaust leak can affect the O2 sensor it might. The leak may be driving the computer to a lean mixture? Not sure? If it was lean you would have told us that so how about a little more info on drieability. How long do you drive before you get hot? Have you checked your engine heat with a temp gun vs gauge reading? What spark plugs are you using? What timing is your engine set at? What is your fuel pump pressure?

Well check this stuff out and post more info pls

Yeah I guess that could help huh....
It's an 89 with a 69 306 ci motor. It's got a hydraulic flat tappit cam with 543" lift and 292 Degrees of duration. We put the Efi on it with the reverse flow water pump like it needed, it's got the right firing order on it. I flushed the radiator and the pump seems to have no leaks or anything. It doesn't get hot until it's warm and you get into traffic or it's just hot outside. we do have an electric fan on it, and kinda wondered about the clutch fan but didn't know..

Clutch fan? They are directional as well. Got the right one?

On a different note: Funny you won't believe how many people put the fan on backwards. The car I checked was running and what caught me by susprize was my pants legs were flaping. Humm fan pointed in the wrong direction.

See ya! sorry we couldn't get a fix right away.

Well, I don't have a clutch fan in it right now. IT's my buddies car and he couldn't afford the blades so we put an 18" electric auto zone fan.

Does it run cool while when you are running at highway speeds or does it heat up only around town? Is the fan turning the proper direction? Is the thermostat working? Does the coolant foam up when it's cool or only when hot?

Hi,

I've got the same problem.. Mine is a '90 LX convertible 5.0...
It would overheat constantly to the point of my being afraid the heads would warp or something. In any case, i've taken the heads off and see no problems with the gaskets. I'm gonna get the radiator professionally flushed and cleaned.
Here's my questions: I've got a stock engine and put a new water-pump on it.. I'm afraid that this new pump is a reverse flow or something.. how do I tell? Anyone got any pictures of the impeller on the pump and which way is the "right" way for it to turn?
thanks,
--mark

Well we used the same pump on his old 5.0 HO and still have the serpentine belt set up but I'm starting to think that it is just needing the clutch fan back on it and take that old p.o.s electric fan off. I'm getting ready to do the exhaust this weekend on it and see if i can get a fan for it. I'll keep you all updated on it. Thanks for all the help, very much appriciated

Yes it is the late model front cover. the only thing we really used for the new motor was the short block.
