I suggest checking the thermostat. A lot of people like to run a low rated thermostat such as 160 degrees but all that does is allow coolant to be pushed quickly through the engine without allowing the coolant to disapate heat. Look at the GM Canada recommended temperature rating and make sure you have that.
Second make sure you have a fan shroud, the covering over the fan and around the radiator. This must be there in order to have proper cooling.
Change the water pump because it's bypassing the motor, check the hoses for pinching, and check for white smoke out of the exhaust. The last one is the head gasket because it will get hot if the head gasket burned from a water jacket into the combustion chamber. White smoke and a antifreeze smell at the tail pipes will indicate that water is getting into the combustion area. You probably didn't change the antifreeze and it gets acidic which attacks the head gasket. Mark sure you flush it.
Thanks Guys Am going to get the heads off just to make shure and for my own peace of mind i replit the motor my self so i have to check it out . Does any one have a picture of a 283 in a 65 whit a fan shourd .I hade a 6 in the car before now i have a 283cu so id like to see what am going to look for if anyone has a spare one an like to sell it let me no thanks .Rene
One more thing how many blade shode the fan have the one i have only 4 blade is that good or shode i get one whit more blades and how many blade

I'm not sure what "today i remove the dom" means, but here's a number things to think about. - You haven't indicated if this is a recently rebuilt motor or if you've had it for a while. - Many things effect engine temperature, including initial spark timing. Check your timing, and maybe baseline it at say 6 degrees BTDC. Is the car running lean? That can effect engine temp. - What's the condition of the radiator? Is it plugged up? - Verify your upper and lower radiator hoses are not kinked. (the lower hose should have a spring inside it so it doesn't cave in). - To verify you don't have a airlock in the cooling system, drain the radiator, and disconnect a heater hose where it goes into the intake manifold. Fill the rad, and you should feel air coming out of the heater hose fitting on the intake. Just be careful not to fill the rad too much before replacing the heater hose or you'll have coolant running out of that fitting. - You've also indicated you removed the thermostat, if you reinstall maybe go with a 180 degree one.
odds are the radiator is plugged. run the engine up to 'temp' run your hand over the core (engine off of course), it should feel almost uniformly hot/warm from top to bottom. if flow is restricted it'll feel much cooler in the lower half.
I would sure check the air lock situation. I've had that happen a couple times on 2 different engines after they had work done on them and we had filled them up with coolant. It sometimes isn't thought of but it will sure shut you down. At this time of the year if that rad was keeping your six cool it should keep your 8 cool too but you'll probably want to put in the spacer section so your rad gets closer to your engine as the 8 is shorter than your 6. Good luck.

One more thing how many blade shode the fan have the one i have only 4 blade is that good or shode i get one whit more blades and how many blade
also ensure the radiator cap is the proper one, and working correctly. We had a guy in our club who put a V8 into his early 50's car, and was still running a 7lb rad cap. He said it would puke out coolant all the time.
Proper cap should be a 15 lb. AC Delco model was an RC15, but is now replaced with a RCxx (I can't remember, I want to say RC23, but an AC Delco dealer should be able to help you as they'll have the cross-up number from RC15) New rad cap is about $10.

Hi Rene. Sorry to hear about your over-heating problem. I have a '67 Beaumont SD with a big block and had the same problem for the 1st two years I had the car. I figured like you if you don't ask. I requested help also on a different site and got tons of suggestions. I was determined to get rid of this problem so I tried most of the suggestions that made sense. I ended up spending $2000.00 trying to cool the car and nothing worked. At the end of the 2nd season, there was a slight knock in the engine when idleing, so I decided to get it looked at during the winter months. I decided to do a complete engine rebuild and make a few minor improvements while the motor was apart. In the process we found the cause of the over-heating. Water circulation was being restricted. The holes in the block and the heads were about 2" square (about) One of the holes in the block had slag in it closing the hole to about 1/4 inch in diameter. According to the mechanic it was a build of slag right from G.M. when built. The motor was put back together and I have been driving it for 3 seasons, this will be my fourth, trouble free. I run down the highway now at approx. 180 degrees instead of 195. I use to stop at a red light and it would jump up to 210 / 215, and if I got caught thru. a second light because of heavy traffic it would jump up to 225 / 230. Now I stop at railroad crossings and even cruise at Woodward and it climbs to 200 degrees Max. Hope this helps. Leo
Thanks againg guy .The head are of and every ting look ok .I when to the auto parts store to get some new gasket they told me 283 and 350 dont have the same gasket i look it up and the look the same i will ne today because am getting the new one that are for 283 .Tonight am going to get it all back together the look at some other option .The rad look pretty dirty .Am no shure if i have the corect setup for the fan i have a space about 6 inch long to get the fan closer to the rad the fan is about 2-3 inch from the rad if any one has a pic of a 65 whit a 283 that would help me am going to get some pic of my set up and post them latter today.

When I replaced the 40 yr old waterpump, the dealer asked me what engine? Reason is that the shaft holding the fan has different lengths so that you must fit the right one to get the fan running inside the shroud. I suspect the same applies to V8 CID!
The spacer you need for that car is for a V-8 car. A 6cyl rad is smaller and doesn't use a spacer. I will post a add tonight with both of your options. I have never seen a fan shroud on any 65 beamont. None of my cars have it. 12 Cars. The post will be 65 Beaumont fan,rad, spacer set-up.
I dont have a gauge just the light ,the sending unit is on the dome right beside the upper hose outlit .The car has about 300 hundre mile on it it sill new when i just go for a small drive it overheat .Am going to get a new rad cap and try that . The motor came out a a 64 impale or chevy.The rad is 24inch by 18inch it was used whit that motor. I clean out the rad today it was pretty clean ,Am going to try a fan whit more blade also am not going to stop till i get it fix . Got every thing back togeter and starded the motor .

This is in another thread, but you are missing the radiator spacer between the rad and the craddle. Also your fan spacer block will then be too long. It looks to me like your fan is way to far back from the rad, even with the rediculusly long spacer. See other thread for pics of the rad spacer.
