ismthis a new motor? if so whats done? and what fuel pressure are you running? a lean mixture will causemcooling issues to because there wont be enough fuel to cool the pistons in between fire.

Not new motor. Paxton fuel metering is at about 35 to 40. Had supercharger on it but bearings were bad so its not on right now. Last summer started runing hot found a bunch of leaks fixed them and just havent been able to get under control sense. Runs fine as long as is not in the 90s outside just dont get it Car was cold and drove home about 2 miles after work its in the 90s out right now car was runin about 195

Sorry I didnt take too much time to read all the responses but have the heads been removed\modified in anyway because maybe the water jackets are misaligned/plugged/backwards in the heads causing reduced flow or cavitation therefore yielding an extreme build up of heat . Its a long shot but I figured id ask

Re: Cooling prob

See if you can get a mirror and light and check the back of the heads. Not sure they do, but if they have the small freeze plugs in them, one could be leaking.
Otherwise I would agree with the intake gasket possibly leaking.

No problem, good luck finding the issue.
Be sure to eyeball the edges of the intake too where the coolant passages are.

Hey have u knocked out the temp sender as mabye a culprit. If u have changed everything to deal with the cooling system and still reading hot. This is just a idea but get a buddy with u and find the temp sender on the lower intake and unplug it. Then u turn the key on amd get your buddy to ground the signal wire thst goes the the temp sender and thrn u watch the temp gauge and it will peg all the way to hot if it's workin correctly

Sensors are all new have autometer gage to it reads the same is crazy only gets up to about 210 when driving and is warm out. I can stop and let idle and it cools back to 170 180

---------- Post added at 11:46 AM ---------- Previous post was at 11:20 AM ----------

So im sure all the leaks are fixed. I have a electric that kick on about 170 and high flow 160 thermostat from summit car will idle fine never got hot. Took a long drive last night didnt loose any coolant but on freeway it will get up to 210. 215 then i can pull over and sit at idle and it cools back down to about 175. I dont understand wth. Or on a down hil in 5 th at about 22 hun rpm just cruzing it will cool down then on flat ground at same rpm it heats back up. So confused

1. The 160° thermostat is to cool, put the factory 195° back in it.
2. You evidently have an air flow or coolant circulation problem at speed.
3. Make sure your fan and water pump are turning in the correct direction.
4. If your water pump is old the impeller could be worn out or damaged.
5. The fan should draw air from the front of the car and blow it back over the engine. It is easy to wire them wrong and have them blowing the wrong direction.

Water pump is new and i have sat watched the coolant circulate great. I had that thermstat bake in last week and it just made the prob worse. Realy confused right now have never had this many probs with temp

---------- Post added at 01:02 PM ---------- Previous post was at 12:58 PM ----------

Fan is def pulling air not pushing. Im runing my timing at 14 btdc. Car runs hard but u think maybe to far. Maybe go back to 10 or 12

You timing advance is not affecting the temperature, but take it back to 10° until you get the cooling sorted out.


Are you sure you got the correct water pump and that it is turning in the right direction?
Just because you can see coolant moving doesn't mean it is circulating properly.


You may have some air trapped in the system. Try finding the highest point that you could loosen up a fitting or something to let any trapped air out, but be careful with hot coolant.


Are you sure your fuel pressure is correct and the engine is getting enough fuel?
If it is running lean, then it will heat up.


Make sure there is no debris between the radiator and AC condenser too.


Have you flushed and cleaned out the cooling system?

There is no way to tell that I know of with the pump installed.
Maybe there are some numbers on the pump or receipt that you could cross reference at the manufacturer's website?


Without a wideband, you are limited to pulling and inspecting the spark plugs.
There is an article/pic in one of the sticky threads on what to look for I believe.


Also look for headers that glow red in low light conditions. That is an indicator it is to lean.

The coolant will still circulate, just not near as well as it should.
The flow should move from the top hose over to the bottom hose.
The top hose is the return from the engine and the bottom hose is the water pump suction side.
