hey all, just need to know where the temp sensor is on an 89 vette and how hard is it to replace?

 

I think there's 2 of 'em there imb...

I've seen posts here tellin' where they are; 'search forums' your best bet, might take a little while...

 

[1]Engine coolant temp sensor:front of engine below throttle body. [2] outside temp. sensor :right side of engine , top right corner of radiator. [3] In car temp. sensor :coupe above left seat near courtesy light: convertible center of lid of cargo compartment.[4] Oil temp. sensor: left rear of engine, above the oil filter.How hard to replace is a matter how bad you need to replace it

 

I don't want to even think about starting that project[>:][&o]

 

thanks guys, was able to find it! The reason I am replacing is because in my last post, I talked about how my car is having a very hard start ans stalls when the car is warmed up ( 200F+ ) and after talking to some people, the major respones I got was that is may be the engine temp sensor. I am still open to any ideas that it may be. There are no codes being set ( which is why im concered that its NOT a sensor ), the injectors are a year old, no white or black smoke on startup. Thanks all!

 

Shotgun fixes are expensive. Could be MAF, but really need to look at datastream to determine cause, a misreporting CTS (Coolant Temp Sensor) will certainly show up under data on a scan tool.

 

yea, I would hate to replace it and that not be it. I wish I could get my hands on a scan tool, but I do not know anyone who has one. I grounded the dignostic ports and no codes were stored and a check engine light has never came up. I had it in the shop about 8 months ago for this very reason and they said it was a PCV valve and the IAC motor was very dirty. So they cleaned it and replaced the valve and it seems to work, but its back to the same ways!

 

any sugestions?

 

Try tapping on mass air flow while engine is idling. If you get a stutter, there's your problem.
