Normal operating temp question

My car has a 327 small block. Recently I installed a new Edelbrock water pump, new fan clutch, shroud and new t-stat. Last week I remived the radiator out and took it to a shop to have it flushed and cleaned.

Basically I have a brand new cooling system. My question is...what is the Normal operating temp for an engine like mine? Also...how can you tell if the fan clutch goes out.

Thanks.

Re: Normal operating temp question

The Chevrolet line mostly was based on a 195 degree thermostat. The specs for Camaro in 1969 state 195 as the normal for all engines. Some folks these days install 180 to be a bit cooler.

So under normal operating conditions the 195 thermostat should begin to open at 192 give or take a few degrees allowing coolant to enter the radiator and come out the bottom cooler than entering the top. The thermostat should be fully open by 227 degrees.

The thermostat will cycle open and closed as need be to keep the operating temperature at or around 195 - 230 degrees. Under extremes such as climbing grade, towing and hauling conditions the operating temperature may be higher. The reason the system is under pressure is to increase the boiling point of the coolant so it can run hotter. SO as long as the pressure doesn't get over 15 psi, or the coolant doesn't boil you are golden.

Re: Normal operating temp question

QAs Brian stated, increase system pressure, increases the boiling point.
A 15 lb cap will increase to 257F.
Typically, radiators and cores are tested at 50 PSIG.

For testing a clutch fan, at first start-up, fan will turn as clutch is locked up.
About 15-20 seconds later, clutch should unlock.
You can usually hear the fan - wind noise.
Tip: Always store a fan clutch with mounting pad pointing up.

Re: Normal operating temp question

Dont overfill your radiator either. These are designed to NOT be full like today's systems. There should be a dash line molded into the radiator a few inches below the cap that you can see, dont fill above that. The coolant needs space to expand while doing its job.
