i am having a problem with my engine coolent. i had my heater core replace twice, both time they "blew" up. the repairer said that it could be the computer because he disconnected the fan and said that the computer should kick in automaticly, he said that the fan didnt.
-i am not sure wheather it is the computer or the "engine coolent temperature sensor"--maybe my mechanic is lying to me.

can you please give me more info on my situation. thank you in advance!

I have a problem with my check engine light. Well i went to the garage and the guy told me the code problem and it was P0342 that mean camshaft sensor. So i buy a new camshaft sensor and after that the check engine light go off and 1 day after the light came back on and it was the same code camshaft sensor. i need help with that .

[i had that code for my cav. but it was because the positive lead was bad. test your + and - connection with a multimeter and make sure you have 12 volts constantly while the key is on
