Drained the coolant and thoroughly flushed everything. There was absolutely no gunk or sludge anywhere (except a bit of dirt dislodged from backflushing the heater core). Replaced the thermostat and gasket with new (OEM) after testing/verifying it in a hot water bath. Also replaced radiator...
I'm glad to hear that! Makes me feel a bit better, but still confused as to what these silver floaters are.
I took a good look at it and the radiator is pretty spotless. I pressure washed it (as good as I could without removing anything) a couple months ago and it's still clean from that.
I'm...
Great read! Thank you for linking this. I think I will do a Blackstone OA but from what my symptoms are, I think a blown HG is very unlikely. I went ahead and hooked up my "burp coolant funnel" thing and ran the engine for ~30 minutes with heater on max and rear heat on. Revved to 2500rpms a...
That's interesting... Maybe I'm misremembering what he told me, but I could have sworn that he said "it blew the head gasket but was professionally repaired". Maybe he was just referring to the prior owner (ie your mechanic)?
I don't routinely check the coolant at the cap, so it could have been...
The overheating used to be both on the highway (uphill, AC on) as well as idling (AC on). I modded the fan clutch (45mL of 20k cst oil) and that seems to have resolved the issue while on highway, but I'm still overheating while idling with the AC on. And by overheating I mean ~225, just enough...
I'm actually planning on replacing the radiator (along with rad cap and thermostat) because I've been having some bad overheating problems this summer. Already modded the fan clutch, which helped, but not enough.
Since I'm planning on replacing those with new and flushing the coolant, if it was...
When I was draining the old fluid, I used a heat gun on the bimetal spring and the 2 valves opened up just fine. However, I don't know at what temperature they opened. Could it be that that adjustment is off?
Or, is the fan clutch behaving normally and I have a cooling problem elsewhere in the...
Hi all,
I've been dealing with some fan clutch issues, so I modified my original Eaton fan clutch by draining the original oil and replaced with ~55mL of 21k cst silicone oil (50% 15k, 50% 30k). I tested it out today, and everything seemed to work great. During normal in-town traffic my temps...
I appreciate all the feedback, but I will continue doing this myself. The initial headache for me was understanding the ins and outs of the differential and how to do it correctly. So there really isn't any headache remaining. Sure it takes time going back and forth in order to get the depth...
