Engine
1954 235 z motor
Been driving the truck to work the last 6 weeks or so.
Ive noticed I've been puking just a little coolant and have to top off after about the 4th trip
Gauge reads normal. 160 with a 160 stat
Up to 180 going up the hill on the way home then levels off back to 160.
7lb cap
Raditor 4 years old , U.S. Radiator
Today when I got home I took temp reading with one of those laser deals
Front of block read 170
Rear of block read 195
Is this normal?

Try installing a coolant recovery tank so the overflow gets sucked back into the radiator as the engine cools down again. That can also be caused by keeping the radiator overfilled- - - -leave a couple of inches of expansion room in the top tank, with the coolant just above the level of the tubes.

Just thought it was odd that this started happening after not driving much this summer.
I don't know what the danger temp is on the block
I hadn't had a need for a recovery tank since I put the truck back together in 2010
Should be simple to install

No easy cure, but it's been dealt with by Chrysler in the Spitfire and Cummins in the Dodge diesel. | | | | | Joined: Feb 2004 Posts: 29,805 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,805 | A 7# cap raises the boiling point of the coolant to 233 degrees at sea level. If you're hearing gurgling in the system, that means at least some places inside the water jacket are getting a lot hotter than the laser is showing. Since the temp inside the cylinders approaches 2,000 degrees under load, that's not surprising. Just put a puke tank on the system, and stop obsessing about it. A dangerous overheat situation will result in a boil-over, not a little dribble of coolant.
