Glow Plugs
Hey guys, havn't been on here for a while but yesterday I went to take a trip to new mexico and my engine light came on. So... I got out my code reader and it said something about a glow plug/heater something malfunction. so I took my trip and after a couple starts the light went off. so I don't know if it was just a freak thing or what. I havn't started it since. but I have noticed that it has been harder to start lately. i have 2 brand new red top optima batteriesand I put in a fuel additive. so maybe they are going out???
So I was just wondering a couple things.
1. how hard is it to replace these yourself?
2. how do i know which one is bad?
3. how much will it cost?
thanks

Piece of cake.
If the code was a p0380 ... it's "most liekly" a bad glow plug, but could also be a bad glop plug module.
Pull both fenderwells. grab a test light. clip the alligator clamp onto the Positive(+) battery post and probe the nut on a glow plug. if the test lamp lights up bright, then that glow plug is good. move onto the next. if you get one where it is very dim or does not light, then recheck your connections and if it comes up with the same result, then that one is bad. test all 8.
once you have all of your "bad" ones figured out, they are real easy to replace. 8mm and 12mm sockets are all you need. Just pull the old one out and put the new one in, easy as that.
glow plugs are about $10 to $30 a piece, ebay is a good place to find them, or your local dealership should have them.... but the price will go up.
