Ive tried researching to no avail. I know i need a 180 degree but cant seem to find them item specific anywhere? I wondered why my truck was overheating until i pulled thermostat housing and nothing was there. Can someone cross reference maybe something i can get at local parts store? Im not sure on the fitment since i dont have one to go off of.

Can I use a universal one?

Your truck would not overheat because of the lack of a thermostat.

I read somewhere that with no thermostat it doesnt keep fuild in the radiator long enough to cool it?

These folks say it can lead to overheating?

pking75, what kind of shape is your radiator in? Might need to be serviced. any signs of corrosion? I checked a thermostat oem AcDelco 19114426 180

pking75,
go back to that post and read the input from Pre '68Dave. Click on his thermostat myth link.

For 4.00 ill put one in it anyways and see what happens. Yeah the radiator aint in the best of shape and i already planned on buying an aluminum one.

Not all folks at that link.

A thermostat will bring you to running temp faster, which is most likely better for the engine and for more efficient pre-warm-up driving.

Who cares just purchased a 2 row aluminum radiator off ebay and will add the thermostat since its only 4 bucks. Should be good to go then.

Thanks Guys

Is your water jacket clean. Does coolant come out when you open the petcock on the block below the manifold to the rear? You should check that out before you put the new radiator in, so you won't send any crud into the new radiator.
