Yes it's too warm for my preferences... I shoot for between 165-190

200 is ok. If it start getting higher then I would worry. But 200 is good.

165 is cold. Engine oil needs to be atleast 180 to properly flow through the motor.

Yeah I understand.. Mine never actually get that hot unless I drive it in the summer then it's 190ish then when fall and winter it runs 170.. I've never messed with it and it runs great.. I say this using a stock engine temp gauge so it could be a lil higher..

200° is good...if you shut your car off it will rise as the coolant isn't circulating,but will drop as soon as you crank it back over..mine runs 200° steady if I shut her down 210°-215° and goes right down when I turn it over....try it..

Yeah the stock gauge isn't very accurate. Lots of people always try to throw the 165 thermostat in there thinking they are gonna help there motor out when really its not good for it. The stock is 190 something because that is the optimum temp.

Ok...but like Dreamstang said watch if while you're driving it raises above 200°...and im assuming you have a mechanical temp gauge that will read temp with the car on or off?..

165 is cold. Engine oil needs to be atleast 180 to properly flow through the motor.

When you run them too cold you run the risk of the ECU going into cold or limp mode which will feed your engine too much fuel which washes down your piston rings and dilutes your oil. This causes premature wear and eventual failure to your engine.


Engine oil needs to be at 180° to properly lubricate your engine as dreamstang said. If it is too cold it will not properly lubricate and your engine will suffer premature wear and failure.


Were I you, I would see what thermostat is in there and install a stock 195° if it does not have one. Your engine operates better and more efficiently at the proper temperature.

Today my engine temp was almost 250 but I was kinda driving it rough I guess you can say is that bad that it gets that high? And my oil pressure at a stop sign dropped to below 10psi. Usually its no lower than 20 but no higher than 40. I never noticed but does it normally drop when idling. When I gave it gas it went up a bit.
Sorry the oil pressures off topic of this thread but I didn't think a whole new thread was necessary

250° is high definitely something going on there..fan issue or bad tstat possibly..do you have a fan shroud?..and the low oil pressure is most likely from a high mileage engine.worn bearings and what not:/

250 is to high. I wouldn't drive it till you get that solved. Let's start with the basics. :
A.. what kind of fan do you have?
B.. is the thermostat sticking?
C.. do you have a shroud?
D.. what is your timing set at?
These are all important things. And it may help to flush out the radiator really good.

As for the oil pressure. It is normal for the pressure to be low at idol. But 10 is too low. The oil pump is driven off of your distributor. So the pressure will build when the rpms build. Make sure you have the proper oil in it. But sometimes this maybe a sign for a rebuild. But don't panic yet. First make sure you have the right oil in it. And maybe we will get some other opinions to.

What would be the correct oil?
It either sounds like your t stat is stuck or you do not have a t stat at all which means it is constantly circulating and not having enough time to cool before re entering the engine if running it hard.
Have you checked your coolant lately? Also be sure you have the correct antifreeze mix, if it's just straight antifreeze that will def cause the engine to run hotter.

If no tstat it would run way cold..

And yes checking coolant level would be a must!..

But if you were romping on it hard for a while the temp would get up there, not saying 250 up there tho

I run 5w 30 in mine. The only reason I said that, is because some guys have a tendancy to run super light or heavy oil. Which will affect you oil pressure.

I think diff weight really only affects before it gets to operating temp as far as 5w-10w...unless running a thin 5w-20 or a heavy 10w-50 that would affect overall pressure a bit more...

Yes I understand. I just have a Babbitt of throwing some not likley but easy to check stuff in. .

Another direction I was heading with this, which I forgot to ask. Is I wonder what his idle is set at. Since he is carbed and cammed, it is possible that his idle is really low. I know I set mine low just cause I like to hear the lope.

Yeah im sure ya knew that already!..
I have low oil pressure at idle as well but it wont drop below 10 at idle..though with my underdrive sitting at idle for a while the idle will drop to 600ish dropping the oil pressure a bit further...hmmm wonder if the op has under drive pulleys??..

If you were running down the road lets say at highway speed it shouldn't get that hot even if your fan isn't working. I'd check your thermostat, its either stuck closed or could've been put in backwards, ive seen it done a few times. If thermostat is ok check the rest of your coolant system for leaks(hoses, radiator, water pump)

Good advice. Some t stats will go in backwards, but I don't think mine will. Also another thing to check is the radiator cap.

Re: engine temperature?

alright well my fan wasnt working right i have a dual fan i wired it up to a toggle switch so i think that part should be good hopefully i run 5w 30 oil right now and about the rebuild it only has around 3500 miles on the motor so could it be going that quick? i know when i got the car there was next to no anti freeze and oil didnt even show up on the dip stick that guy only had it for a month before he sold it to me but could it be messed up that soon

---------- Post added at 10:22 PM ---------- Previous post was at 10:21 PM ----------

and i idle around 700ish i know someone was talking bout the idling'

---------- Post added at 10:23 PM ---------- Previous post was at 10:22 PM ----------

maybe even 600ish sometimes

---------- Post added at 10:26 PM ---------- Previous post was at 10:23 PM ----------

and i run water not antifreeze was a little low but not bad

600 ish is a little low. If you set it at 7-800 your pressure maybe a little higher. And what kind of gauge do you use?

You can get an adjustable fan controller that comes with a relay for about 40$. It wad one of the best investments I did to my car. It had a temp sensor. And you can adjust it to kick the fans on whenever you want to dial in your temp just right. Call summit racing and they will hook you up with what you need.

Your oil doesn't look milky does it? or does your coolant look any different?

i have auto meter gauges and how do you adjust the idle ive never done it before which speaking of that i have to do it on my sable this weektoo lol

and i use water instead of coolant i need to buy some anti freeze but na the oil doesnt look milky

im gonna see tomorrow when i go to school if the oil pressures still low bc that was the first time i saw it go that low

Your sable will be way different since its probably efi. But on your carb there is a flat head screw right by the throttle on the carb. Just turn that in or out. It will be in to idle higher.

Well I'm assuming your idle may go down when the fans on. But yeah 7-850 range should be good.

Re: engine temperature?

alright thanks ill do that tomorrow after school and check the oil pressure and see if it goes back up and hopefully the engine temp will cool down a bit is it bad if i have water not antifreeze in there for the summer? i know its bad in the winter but what about the summer any differnece?

I'm not sure of the exact science. But I would put a 50/50 mix in it. It may help some but I doubt it will solve any problems. It may evaporate slower also.
As for the oil pressure. It may help keep you from being to low, but will also not solve any problems if there are any or not. We will see though.
