Well I had to go and mess with it didn't I!! Started the truck Sunday turned on the a.c. to cool it off turned around and it shut off like I had turned the key off
didn't have time to mess with it so I left it be and we took the wife's car since we were already late to a baseball game.
So after waking up Monday and taking the new blazer before I even left the parking space the rear view mirror fell off in my hand trying to adjust it and the entire day went down hill fast!!. Sitting in a meeting this am after getting to work I get a phone call from my cousin that I knew would be coming but was dreading that my grandma passed away that night
then an hour later my delivery team calls me and says the truck is "squirting something from a metal hose" so ask then to send me a pic and where they are. Of course they are over an hour away so road trip here I come. It sprouted a leak in one of the heater pipes so I rigged it up with some muffler putty and then wrapped it in muffler sealant tape and sent them on their way. The fix worked for two days until I was able to swap the part Wednesday morning.
While on my road trip I noticed the blazer was running a bit warm even on the highway so I figured I should swap the tstat. After letting it cool for a bit back at work I pulled the housing to find it didn't even have a tstat in it! That should have been a sign if it was running warm with no tstat but I figured since the PO was running straight water that wasn't helping anything so I didn't think much of it. Well driving home to fix the burban I'm two blocks from home and the temp spikes and then pulling into home the gauge drops flat as I'm pulling into my spot! Shut it off and pop the hood to find the lower rad hose spewing water. No big deal except I have to pick my son up from daycare in 45 min and I'm now stuck at home with two broken down vehicle's and no way to get him. The wife was at work in a meeting so reaching her wasn't happening so thank god for good friends 10 minutes later I had a buddy picking me and the car seat up to get the kid and another lined up to watch him for me while I messed with trucks
Anyway I swing by and picked up the rad house and started on that and the husband of the friend watching Bentley came to help me so we had the hose swapped relatively quickly after he made a trip top his storage locker to get his hose clamp pliers and filled it up with coolant started it and everything is good... Well kinda it still got really hot really quickly and I could feel the tstat open but still stayed hot at idle but weirdly if you held it above 2k the temp would drop so to me that says water pump issues. So I closed it up and went back to the burban. I ended up replacing all the coolant lines plus the water pump for good measure today and all is well with the blazer.
First thing I did was try fuel in the tb and no change so it's a spark issue. Checked all connections everything is good so I pulled the cap and the button on the cap is gone fried right off and the rotor looks like crap!! I kept going down the list and found that the pickup coil was shot so I replaced the entire dizzy and all is well now.
The spot on the left is just from my finger
And the inside of the cap
