Dolly's Cooling System Woes

The fan shroud can be moved up or down to align the fan in the center of the shroud hole......and should be to get the best performance of air movement. The left and right alignment should be spot on once the radiator is mounted to the core support.

Axel-Breaker-Earl So it sounds like your saying it is best to mock up the radiator and shroud with the fan installed, mark the holes on the radiator brackets and then make the permanent mounts. That way I guarantee a centered shroud for maximum air volume.

Wouldn't hurt. You state your radiator is a little different than mine, but with my radiator and fan shroud I didn't have much wiggle-room where my fan shroud could be mounted due to the radiator frame and the outlet pipes for the radiator hoses. I didn't need to use small "mending plates" from the hardware store to make extension mounts.

By the way: in response to your earlier comment, I did not polish the aluminum radiator, that's how it was and is.

This post is awesome. Thank you for taking the time to create it. Question for you, where is the temp sensor located on the enging?

drewmoney Question for you, where is the temp sensor located on the engine?

The stock carbureted B2200 has three temperature senders. One is on the intake manifold, for the ECU. One is on the radiator for the PTC heater plate under the stock carburetor. These are essentially for pollution reasons and definitely not needed with an aftermarket Weber carburetor.

The third sender is for the temperature gauge in the instrument cluster.

Cusser Appreciate you putting this together for me. Doing a head gasket replacement and notice the temp gauge doesnt work in the cab. Got a replacement but wasnt sure where it was. thanks!!!

drewmoney

Cusser,

Thank you brother but im not sure if mine is different cuz its not there on mine. the oil sending unit is there but not the temp sending unit. any other possible locations?

On the carbureted B2200 engines, that sending unit is tough to locate, hidden under a hose. I'm not familiar with fuel injected B2200 engines but would imagine it's in the same location.

Could someone in the past sheared that off and the broken stub is still in there? Got really good photos of that area?

I posted earlier what my B2200 temperature sender looks like.

Axel-Breaker-Earl

Do you have a fuel injected B2200 truck?

drewmoney

Axel-Breaker-Earl no it is carbuerated and cusser was right i found it

Cusser

Sir, you are good. I found it it was sheared off. trying to find a good replacement cuz the one i had ordered from rock auto is to big. ordered a different one and hope it fits. But now the question is where does it hook up too?

Cusser

drewmoney the question is where does it hook up to

Should hook up to a yellow wire with white stripe, look for an un-used wire coming out of the harness near there; if the connector is gone a female crimp-on "bullet connector" can be used. If all else fails, a new wire could be run to the instrument cluster.
