Hello everyone i finally got my dream car 1969 camaro and i love it. I was wondering if you guys have ome info for me. The car has a huge motor 454 bb crate in it and it gets really hot like around 210 or so i want to cool it down cause if she get to hotshe wont start back up until she cools off to about 190. Please let me know what i can do. Hope fully get some pic up tomorrow. Thanks

 

Change the Thermostat to a 190.

 

how about running engine ice in with your coolant its suppose to lower your temp by 20 or 30 degrees

 

Remember to not run too much antifreeze. It's the water that keeps the engine cool, not the antifreeze. As the name implies, it keeps the motor from freezing and corrosion too. Drain the entire system, pour in 1 gallon of antifreeze and fill the rest with water.

Another idea is that your water pump is old or bad. Or, the block could be old and the water passages blocked up like clogged arteries and the cooling is less effective when the water can't get through.

 

Do you have a fan attached to the motor or is it electronic? If the other suggestions fail you might want to consider upgrading the fan too.

 

Thanks for the ideas guys i will try the engine ice. And yes it has an electronic fan.

 

The electronic fan could be going out. I would try cleaning it up or checking the connections. Also you may want to consider replacing it.

 

thats a easy one...sounds like your timing is too far advanced.......check your timing,might want to add a cylinoid shield on the starter if it dont have one,its obviously bad or getting really hot from no shield,but if your timing is too far advanced it will make the starter start hard and run hot......

 

Others mentioned some of these but I'll list them

Faulty gauge, you could actually be running hotter....or cooler.....

Timing to far advanced

T-stat not opening properly, causing blockage

weak water pump

radiator slightly clogged

slow fan speed

high compression engine ( tough to cool, system has to be well thought out)

fan shrouds missing, the fan shroud directs air over the engine, very important, always over looked

weak radiator cap. pressurized system raises the boiling point of the system

Not enough fan, small electrics might not push as much at idle as needed.

Too small of a radiator, coolant not actually getting cooled enough.

I'm fighting a slightly similar problem with my car, I start to climb to 210 at idle and I know it's because I don't have enough fan, and the shroud is not present because I haven't found one I'm happy with, and I have the timing bumped up a tad.

Also, where is the sending unit for the coolant gauge located? I've noticed a 10 degree difference on my car. The gauge, mounted with the sender in the head, middle area, runs hotter then the ECM's coolant gauge. Which is mounted next to the T-stat housing. So with mine, the head is at 210 while the intake is 200...

 

nice truck you got....
