I have been taking my vehicles to Valley Auto for several years. So, when I heard a noise in my Chevy Silverado, I went to Valley Auto Electric. Valley Auto did a thorough check of the engine, sending the oil out to be checked and the results showed a gasket was leaking and advised me to replace the engine. I decided that the expense was worth it. I didn't want a blown head gasket while on the road. Thank you Valley Auto Electric for saving me time,headache and unnessary expenses later.
