Power Strokes 1994-1997 Upgrades and AftermarketUpgrading or adding OEM or aftermarket equipment to your 1994-1997 Ford F-Series with Power Stroke engine.
I'm thinking that I'm going to have to put a lower hose heater on my radiator to keep
To keep from breaking my block.(hot frying pan-put in cold water)( it will bust right in half)
You can't add ice cold water to a hot engine and that is what is going to happen when my Kim Hotstart heater brings my temp gauge to half and I start the motor and instantly the ice cold water from the radiator surges through the hot motor, even though it's not boiling hot.
I think it will ruin my motor.

Please elaborate. How does the hot water circulate? Or do you expect the heat would only rise from ?convection?? and when started would then circulate via the engines waterpump?
I'm not familiar with the "hotstart" system, or frankly even heard of it. I think your best solution would be to have a circulating pump somewhere with this heater, and then it won't be an issue.
Never mind, just saw your other thread. I'll monitor that one.

I'll know more here in a few hours. In ten minutes the heater hose and unit itself are hot. It's circulating but I don't think that includes the radiator. I'd be bird happy id it did. It's 30 minutes now and I can just barely feel heat touching the valve covers, or mabe that's wishful thinking. Another hour will tell.

What do you think happens when you normally start the truck up without any type of engine heater? The engine gets hot then the thermostat opens and in comes the cold coolant from the radiator...

True but there is "some" flow through the thermostate before it opens all the way letting enough through I'm guessing to reduce the shock factor a lot, vs an open thermostate with a hot motor and ice cold and -30 below coolent hitting it hard all at once.

There should also be some heat flow through the system anyway. If I plug my factory block heater in, it not only heats the coolant in the block, the radiator gets nice and warm as well (as does the oil). I don't think you should have a problem. Cheers!
I don't know about the 7.3, but from this article about the new 6.7, it looks like thermal shock is something they test during engine development.
Quote:
A thermal fatigue test is used to prove out the engine assembly process by stressing the head gasket, joints, radiator connections and other seals. For this test cycle, the engine is idled and then throttled up to peak power for about 14 minutes. That’s enough time for the engine to get red hot. It’s then shut off and 16-degrees below zero coolant is pumped in and allowed to soak for a few moments before the engine is fired back up to rated power. The shock loop is 150 hours long, or 75 cycles.
I don't know if this would be reassuring or troubling, knowing that it's somewhat similar to their extreme test conditions.

Tomorrow I am hooking directly into the block through the 1/2 inch plug I removed from the back of the drivers side head, just below the back bottom corner of the valve cover. It's 3/8 recessed for a 3/8 rachet or breaker bar. I soaked it with Liguid Wrench Penetrating oil and taped on it a bunch with the hammer and a 3/8 extension in the hole but very softly and more liquid wrench. It let loose nicely, I got to get a nipple to match the 5/8 hose and now I have direct thermosiphen directly into the block. It should make my whole motor like toast at -50 below. 120 to 140 degrees thermostat.
Tomorrow will tell. I'm betting on it. I was over to the guys house who has one and this is how he is hooked up only he's on the right front head and I'm on the back left head, both of us have both our in and out for the tank heater on the same side.
I think it's going to work.
