Over flow - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey everyone,
just have a quick question, my truck has a 350, w/ stock rad. it runs about 190/195 degrees on highway. Everytime I stop and shut off the motor, it spits some antifreeze on the ground from the overflow. Should I be looking at a rad. cap? or put on a overflow bottle?
Thanks for your time.

I would go with an overflow bottle.
I took the bottle and holder for the widshield washer fluid and am using that for my overflow. It looks like it should be there and it works great.

The nice thing is there are endless possibilities for custom overflow bottles. Colored juice jugs, thermos, small aluminum tank, the new Heinekin mini keg, etc., etc.

Most definitely an over-flow bottle. Are you running a shroud? Do you run a stock fan, or one with a modern design? Running that high at speed would drive me nuts.

Thanks guys, will add an overflow for it.
The truck has the original shroud and stock fan. Not sure what thermostat it has in it yet. Again thanks.

In a new vehicle - no (because of emissions, etc). With older rigs, on the highway in the desert - at noon - uphill on a grade, 190/195 is fine - at 70 mph. But on level ground - same conditions, 175/180 is what I consider "normal'.

Idling in a drive-thru on a 90 degree day - you can expect 200/205, but that's no load and a different thing. JMO.
