My 1009 is starting to get me a little hot under the collar this weekend. It seems I have hit that mark where once I fix one thing, something totally unrelated starts to give me trouble. Then once I fix or figure that out, the 1st thing starts all over again.
I recently changed out the entire cooling system, radiator, water pump, heater core (on my 3rd in a month), upper and lower radiator hoses, heater hoses, cross-over tube. Everything but the engine and t-stat have been changed and yet my cooling system still gives me some issues that I am having trouble figuring out.
After the radiator chang out, I went through 2 heater cores within a couple of weeks. The 1st one blew a header seal, the 2nd had a core tube leak, the 3rd so far has been working out okay.
I have been having an over pressurization issue that I cannot seem to track down the source. I checked the cooling system for a combustion/compression leak, nothing. I just changed out the 16lb pressure cap for a 13lb to see if that will offer any relief.
The new radiator had a tiny hole for the pressure relief to the catch can, but it looked like it was way too small, as if the gasket for the cap would cover it, making it useless. So I enlarged it to the size of the nipple that goes to the catch can.
Now the truck doesn't overheat, I have checked the temp at several times to see what it is running at, it always seems to be at the highest, 190°-200°, but the hoses just seem like they are about to burst.
I went out this morning only to see a small puddle of coolant on the ground that got my blood boiling. That set the tone for the day
So, I started to look at other things, my mistake.
Wound up removing the drivers door, to replace the worn out hinge bushings. While I'm doing that, may as well do the striker too!
Oh, and I found out why my headlights keep blinking on and off from time to time, the common overload of the headlight fuse issue. So I have to look at that as well, removed added circuits from that fuse and pending an LMC conversion kit.
Just glad I didn't really have any plans for the weekend.
The only good thing is that I really made some progress on my super high power LED light bar that will assembled and installed soon, pics to come. If everything goes right with that, should be pushing about 80,000 lumens out the front of the truck, enough to scare the sun.
Anyway, good luck with yours as I pound away on mine.
This calls for a beer or 2
