I would think the rebuilder shop would have a vested interest in helping you discover the source of the problem. It's under warranty, so if you have a meltdown, they would have to fix it would'nt they? Of course, there's probably some fine print about overheating problems not being covered.

I had a similar problem with an 83/302. When I removed the hoses to put in the new radiator, I discovered that the lower hose spring was corroded, broken and turned sideways. I don't know if the new hose or the new radiator fixed the problem, but something did

 

MAN WHAT A BUNCH OF CRAP!!! THOSE GUYS AT THAT SHOP NEED TO BE TAKEN DOWN A NOTCH OR TWO, START WITH TELLING THEM YOU GOING TO FILE A COMPLAINT WITH THE B.B.B. THEN IF THAT DOESN'T WORK TELL THEM THE STATE ATTORNEY GENERAL, THEN YOU'LL FILE A CLAIM IN SMALL CLAIM COURT, IT MIGHT WAKE THEM UP.WHAT STATE IS THERE SHOP IN LETS PASS THE WORD. AND MAKE SOME CALLS

 

Nik, You must have a spring in the lower radiator hose. This spring is usually made of brass and keeps the hose from collapsing as the water pump draws coolant from the radiator.

Go to a resturaunt supply, or cooking supply store and buy a food service thermometer. These only cost about $7.00 bucks ($12.00 for a digital) They are very accurate. (call your local health department and ask them where to get one if you don't have a local supply store).

Take your radiator cap off (when cold) and start your engine, rev it to about 3,000 rpm till it gets as hot as it's going to get. put the thermometer in the top of the radiator and see what it says. Does it match to the guage? Drive the truck for a few minutes (still cap off) till it reaches max temp. check the temp. again with the thermometer. What's the temp.? if its 230 or less, you don't have a heating problem reguardles of what the guage says.

Try taking the thermostat out. Is the temp still the same as it was before? High flow pumps usually need a "ballanced flow" type thermostat, as the increased flow can hold a stock thermostat partialy closed. (Milidon and other co.'s make them).

Last point is to have a radiator shop check to see if there is combustion gasses in the coolant. It only takes a few seconds for them to put a tester on the radiator and check.

Tell us what you find out.

 

Nik,

One thing you may want to try and it's cheap...I had a similar problem with my 400. A 190 degree T-stat and it would run up to 210... What solved it for me was I went out and bought a high performance 180 degree thermostat from AutoZone for $8...it solved the problem. Now after driving 30 minutes or so on a warm day in traffic it will only be around 185 or so... Hope this helps if you haven't already done that...
