'32 Ford SBC Heating Issue

Hello,

I have a situation with a '32 Ford roadster. It is now 1 year old, with 5k miles on it. This car had a 160 stat in it since new, 15" mechanical fan with shroud. This car would run at 160 all the time, without ever going so much as a needle-width over 160. It is a GM 350, Carter 600, dual plane, 9:1, simple little motor...275 horse at best.

All of a sudden, about a month ago, it started running 180 for no reason. It didn't gradually start running hotter, just 160 to 180 from one day to the next. It does this from idle to 80....it just has to be some kind of restriction.

I changed the stat, made no difference. ALL parts were new one year/5k miles ago. Someone has suggested that possibly the impeller on the waterpump has come loose or deteriorated somehow. There is no bubbling in the coolant.

I know that 180 is acceptable, however, I want to why this has happened. This car is going to be driven by one of my employees to the NSRA Nat's in Louisville in 2 weeks....not looking forward to any kind of roadside repair....haha...dropped an alternator in Tifton GA on my 3w last year...I had a circle of 15 "good old boys" watching me get that broken bolt out of the block with visegrips

Not sure what ,made it raise the temp all of a sudden, does it ever run hotter than that? One possibility that you might look at is the lower hose, it could be partially collapsing on you causing a flow restriction. You can check it visually after the car is warm and see it "suck" in when you raise the rpm's if it is occuring. Have you changed anything? Added or changed the hood? I'm headed to Louisville also, finishing up my Deuce now, 351C/C6 combo. I'll be working the Dearborn Deuce booth on and off during the weekend, stop by and say Hi.

Wow....quick replys -

As for the sender, I have new SW guages on the shelf for a Tudor in the shop, I could pull a sender and try that. Seems unlikely since the guage sweeps up to temp from cold just fine. Doesn't seem like an electrical issue.

The car has had a full hood on it since day one. I was looking at the lower hose today..seems fine. No changes at all. I just hopped in it one day and it was running hotter that usual. I may have sat a couple weeks between these occurences...I can't remember exactly. The car is so docile and reliable, it isn't a "gauge watcher" type of car...just fire it up, glance at the guages, and head out.

I will stop by the Dearborn booth for sure. Very interested in the new rails. The ASC's are getting worse by the load. They are so bad from the cowl forward now, we are spending hours straightening them and getting them to sit down in the jig before we can begin to do anything.

What is your first name? My name is Tim Davis of Clarke Hot Rods in Daytona Beach.

There's always the possibility that the thermostat is "wearing" some and not functioning as it did when new.

Hello Tim, my name is Dave Wood, Woodsy's Gearhead City, just relocated to Philo ,Il. formerly in Champaign. Those frame rails are beautiful, we plan on running them on both the 3 window and the new convertible when it arrives.
