69 roadrunner, everything brand new including recored 054 radiator, 16lb cap, 180 stat, belts, hoses, mopar performance clutch fan, shroud, etc. The car runs past midway on the gauge and pukes everytime I shut it off. It heats up on the gauge within less than a minute after starting it for the first time. I initially thought my lean condition had something to do with it but I have sorted that out.

My thoughts are defective stat? shop screwed up something when they recored the radiator? cap? maybe something to do with the engine build?

HELP! I am running out of patience with this thing.

Check your timing. Keep total below 35 degrees if posible. Check for vacumn leak around carb and intake. Change stat to a 160 degree. Try it again.

Check your lower radiator hose and make sure that it has not collapsed.

timing is 34 total, can the antifreeze to water ratio affect anything??

A 50/50 mix is all that's needed.

Air bubble trapped in the cooling system? I don't know how you would cure that short of draining everything and refilling it.

looks like trans fluid in the coolant, its all red. what could they have done wrong when they recored this radiator to let this happen??

Sounds stupid but hows your catch can?

Do you have one?

If you do not have one, you are only suppose to fill the radiator just until it covers the core otherwise it will always spit out the water that has expanded.

your only problem maybe that you overfilled the radiator.

Otherwise I would remove the thermostat to make sure there is nothing blocking it. Maybe put a lower temp stat to replace it. Get a thermo heat gun ($40?) from harbor freight and check the actual temp the car is running.

no catch can just the overflow hose as original.

That's bad if you got red fluid. But if it is tranny fluid I would suspect it would be foamy and pink? Is it all floated to the top of the radiator?


oh maybe you have Redline water wetter in there!

Water wetter is pink or red (high concentration) to some people and it would be transparent.

I think also some of the newer coolants are reddish now too.

And the level of the coolant when cold?

coolant level doesnt really change hot or cold, its at the top always. no pink foam and no antifreeze in the trans. I did add a clear water pump anti corrosion additive by zerex but like i said it was clear.

this is definitely trans fluid by the smell of it.

yes its floating at the top you can stick your finger in there and stir it around an d see good antifreeze.

Take the radiator out to the shop who did it. They should be able to fix it. Tell them about your over heating problem too. Don't drive the car until the leak is fixed. Hopefully it is only on way and you are not getting coolant in your trans.

Pull your tranny dip stick make sure it is not foamy pink in there like a milkshake. Water can damage the clutches really fast

trans fluid looks fine but I have $1000 in this trans, is it possible to have it leak one way? I dont want to take any chances, everything on this car is brand new.
