Was a bit scared at first as well, but pulled the trigger . Its solid aluminum all welded ect. looks nice sitting in front of my 350. its a pic of my Jeep torn down for paint, but dont let if fool you I took my Jeep to Dallas twice 2.5 hours each way. No issues
I put one in a 81 with a 258...
The overflow nipple on it points the wrong way (fixes with a looonnger hose)...
I feel the mounting brackets were wrong so I had to mount it inside my grille and use spacers...
I installed the radiator this weekend, everything worked out well.
I also installed an electric fan, wired to the battery so it will continue to cool after the engine is off. However, the fan stays on for ten minutes after the ignition is off.
I would think there is a timed relay in the switch to keep the fan from cycling on and off too much, but 10 minutes seems excessive. I installed Imperial part no. 226203 for the fan controller.
Any thoughts/experience with this particular part? Could I have the power wired in backwards on the relay? No markings on the relay or the directions of which side is to be tied to the power source vs. the fan. Fan comes on at 195 like I want.
The fan kicks on at 195(there is only a single adjustment on the relay.
It's wired straight to the battery to continue cooling once engine is shut off. Once engine is shut off, the fan stays on for 10 minutes(to the second),then turns off. When it shuts off the temp is usually below 120. I would think if its controlled only by temp it would shut off before it drops that low. I guess it's possible the radiator is hold heat for a few minutes, could there be that much difference from the radiator and the temp sensor?
A regular relay is just a powered switch. It's either on or off.
You'd need to determine if it has some kind of timer or not, but it sounds like it's working fine.
Just a quick Google search leads me to believe that this is 100% thermostatically controlled and no timer is involved. And yes, there can be that much difference in the radiator temp and your cooland sensor. The radiator gets major heat soak after you shut off the engine.
Ok, the heat soak makes sense to me. I think I will buy a laser read thermometer and check the temp at the radiator rather than going with what the gauge says. This should help me confirm it. Thanks for the help CSP, I am a slow learner haha
