could someone please tell me where its located and how to replace it. thanks

 

That's the 1 wire coolant temp sensor for the coolant temp gauge. Located under the distributor; thread out and thread in not much procedure here.

 

do you have to remove the distributor to get at it or is it possible to do it without removal of distributor

 

Why did you need to replace the temp sending unit?

 

You will probably have to remove the distributor if you want to make the job easy.

 

okay so i finished up the job the other day and the temp gauge works fine now, but car still pulsates idle until the engine is at normal temp, so waht causes this

 

Clean the IACV and FITV and also bleed the cooling system.

 

how do you bleed the cooling system?

 

Bleeding the cooling system may take 20-30 minutes.

1) Park the car on an inclined driveway with the front end higher than the rear.

2) Push the dash heater lever/**** to MAX heat.

3) Follow the directions in the diagram below (hint: the bleed bolt is located where the upper radiator hose connects to the engine):

 

thank you i will do that in the morning. does the need for bleeding the cooling system have anything to do with the temperature of my heater. its semi warm but definately could be hotter

 

Air bubbles trapped in the cooling system or a low coolant level can prevent the heater from working properly.
