fast idle temp switch

[timarr]

Sir, you are correct that's the sensor. You best bet is napa. It has to be ordered but will 39 bucks instead of 80 bucks or more elsewhere. part # ts7265

Fast idle not working also here......Bought the napa part 34 dollars and Bang fast idle works again..
Thanks to all that helped with this thread

Mine seems to be sticking, thanks for the information. Any other tips on lubricating it? I always appreciate your advice.

The fast idle solenoid is known to either stick or go bad, causing no fast idle. Test for power to it, before assuming the switch is bad. Lubricate it with your favorite spray lube and exercise it by hand to get it moving smooth and easy. Press the throttle down while starting and see if you get fast idle(the solenoid needs no resistance to actuate properly).

Just a FYI Napa raised the price of the coolant switch
Ech-TS7265 to over 100 bucks......

Yup just replaced both the cold-switch and the GP temp sensor, the switch was about $100, while the sensor was $25. A new solenoid is about $115 now. The shaft that goes through the center of the solenoid body can get dirty and jam up just due to the design (complete pass-through).

Probably easiest to work on it while it's off the injection pump. Pull the limit screw out then withdraw the armature from the center of the solenoid body. Clean the center passage then put some dielectric grease in the passthrough. Clean/polish the armature and lube it up too (same lube), reinstall the armature and install the limit screw again. When you put the solenoid back on the truck you need to lube the contact point on the throttle lever of the injection pump with white lithium grease (doesn't displace, does better with metal on metal contact), and then you need to re-adjust high idle per -20 TM (800RPM) when warm.

Make sure you don't forget to check the return spring on the throttle lever

That's correct in only a yr the ts7265 switch went from 39 dollars to 168 dollars in my area. I ve stocking up on ac delco one on our fav. auction site if I see them under 50 dollars.

I just replaced my fast idle solenoid today $98.00 on Ebay was the cheapest I could find it. The technical name and part number are as follows......ACdelco...fuel injection idle speed actuator, #14066255. Mine was shutting off prematurely. when I took it off all the guts were loose.

Just to confirm before I purchase it, the fast idle temp switch should give a full 12V to the green wire going to the injection pump and solenoid when the engine is cold right? When i put the volt meter on the green wire going to the injection pump, i get between 4 and 8 volts. It fluctuates rapidly, and I assume thats why the fast idle will sometimes kick in but cut out immediately or not even work at all.

 

[Warthog]

Yes you should have a full 12v on the green wire when the engine is cold.

Oreilly auto still has the BWD WT7266 switch for $70. While it is still expensive it is cheaper than Napa. And it comes with a lifetime warranty.

 

[m1008chevy]

Thanks for the reply, I wish I could purchase from Oreilly but we don't have it in Canada. Ill be spending 197.99 at Napa .

 

[sschaefer3]

I got mine on Amazon. They have this stuff too.

 

[m1008chevy]

$147 on Amazon, thanks.

 

[Warthog]

Rockauto.com lists the GM version for less than $100

 

[m1008chevy]

Thanks for the help gentleman.

 

[richingalveston]

bought one yesterday at oriely's for 69.99

New guy is in British Columbia with no Oreily's

 

[magic marouke]

ive just ordered this part as the male contact also broke away from the sensor . my wire boot melted so is junk .after putting new connectors on the wires does it matter which way round the wires go on the sensor ?

 

[Garagefull]

After seeing those price increases,I am glad I have been hoarding parts.

napa wants 54 for the part and 16 shipping . i searched for an hour and everyone else is around 100 . rock auto had one for 70
