Leaky radiator drain plug...HELP!

[s13fOr_me]

well...the drain plug on my radiator keeps leaking and i have to add some coolant every week. is there a gasket or something that i need to replace?

Another question. The coolant temp gauge on my instrument panel doesn't work well. after the car's warmed up it just goes a little pass the "C"...i know the CTS could cause bad gas mileage but could the CTS sending unit cause that too?

For your drain plug i would just say to try to teflon the crap out of it and put it back in.

For your second q, you should just replace the CTS. The CTS acts as both the sensor and the sender.. There are actualy two cts's on the 240. One sends a signal to the ECU one sends a signal to the gage cluster.

replace both parts, they wont run more than 20 for the pair.

ya, ill try tefloning the **** out of it today. i actually replaced the CTS for the ecu but was wondering if the sensor for the gauge would cause bad gas mileage to.
