my car doesn't seem to want to get up to a good operating temp especially now that its getting cooler out. Is this because it doesn't have the under belly pan? I also noticed that my fan runs all the time. isn't the point of a fan clutch so that the fan only runs when needed? It almost seems like my fmoc works a lil too well.

 

The fan clutch does not stop the fan from completely spinning; the fan clutch merely slips less when it gets hot. It will still spin the fan when things are cold.

Personally, I like the electric fans better. You can turn them on only when needed, when the temp gets hot.

Have you had your car long enough to be sure the temp gauge is working right? Have you verified temperature with something else like one of those hand held IR pyrometers, or physically stuck a thermometer in the radiator cap hole?

 

yeah i eventually wanna go electric but yeah its pretty obvious by the idle that its not quite getting up to a good temp like it was when it was really hot this summer

 

Check your tstat, it may be stuck open or something.

 

^^^ Thermostat! It's cheap, easy to replace. It has happened to me a few times, it's always been the t-stat.

If you have a carb with a manual choke you can easily tell if it is the gauge or if the engine really isn't warming up by seeing if the choke **** takes forever to return. forever = cold engine

 

^^^ Good point!

The gauge and the clutch magnet work off of separate sensors, so disparity would indicate a failure, but common reaction means true sensing of temperature.

 

the choke doesnt stay out on its own at all i have to prop it out i think that has something to do with when the previous owner removed ratsnest and did a minor carb strip. Ill give the t-stat a try thanks guys

 

Which one of these should i get?

get #24960

Note how 24960 has a little disc that sticks down below the main normal thermostat. That little lower disc is important; it works to cover a passageway in the housing. If you buy one without the little lower disc, things won't work right.

If you are sure the engine is not warming up, then replacing the t'stat would be a good place to start. It doesn't take long to put one in.

 

Note also that the 24960 is a 160 degree thermostat. 15398 is the 180 degree one, same as stock.

 

Tried to order #24960 and it says vender out of stock.

 

I'm just gonna buy the #15389 cuz it's the cheapest durmast that we have in stock so I'll see how that one works. It's only like $8.

 

ok i replaced the thermostat and it still seems to run really cool. later when i get to work ill take a pic of the temp guage and post it so you can see how cool it is running.

 

well i forgot to snap a pic but would removing the fan shroud help? what else can I do to help it reach a good operating temp? also it sounds like the bearings in my fan are making a clacking noise could i just mount a flex fan straight to the pulley?
