Overheating disco 2
Forgive me if there are 7.2 million overheating threads, but this is the first time posting, as well as asking for help after owning my discovery 2 for over a year. It's a 2004 SE with about 119k on the trans and body, and 150k on the 4.0 I popped in there after I dropped a sleeve at 99k. Went through the 4.0 with new gaskets, pumps, etc. did not change out the oil pump gear, but most everything else. It was snowing one day about a month ago,(I live in upstate South Carolina), and I drove the truck about 30 miles home, got in my driveway, temp shot up, and it blew off my expansion tank hose. (It's blown off before and cracked the plastic piece on the rad that it secures to). I've reclamped it since then. After that, it would idle for about 20 minutes, temps would begin to climb, but not reach the oh crap line. I usually cut the car off anyway out of fear when this happens. Thermostat seams to be opening. I purged the CRAP out of the cooling system, and heater core. I replaced fan clutch, and ordered a 180* warm climate t/stat from rovers north, and an oem rad. I flushed mine, it had great flow, with no hesitation..? But drivers side of the rad was way warmer than the opposing side, so I decided to order a new one. All my hoses are the same temp, and flowing correctly, I think... my next idea is a block test, but I had that gasket replaced 18 thousand miles ago. I never try to drive it hot, i always call a tow on the spot, and I'm oddly missing coolant constantly, (not in my oil, my heat works great, no white smoke on start). I know to check the top corner of the front cover, but I figure if it was leaking there I would see spots in my driveway, at least. Pulleys could use replaced, as some are getting tight on me...what am I missing here?
