Did you open the bleed valve to let air out? Per the RAVE, you detach the coolant expansion tank and raise it 8 inches (it pops out, no screws), the pull the upper radiator hose out of the guides on top of the rad, then open the little black plastic bleed valve at the junction front and center. Close the valve when water comes out and put everything back.

Also, consider the fact that there may be a blockage or water pump problem. Remember, the D2 is pretty much the only car ever that doesn't have a thermostat. It is a coolant bypass / relief valve that opens on pressure, not temperature. This is why the D2 has such large temperature swings, the "thermostat" isn't controlling temperature, it is controlling pump backpressure. There's a reason no one else copied this design and LR never tried it again.

Lol... I'm no stranger to the RAVE bleed process. Blockage has crossed my mind. If I go by what I see... there is flow, the stupid pressure cap IS leaking.. as usual. Maybe that is a sign of something else. If I buy another cap, it will be the second one I have bought. All of them wind up being junky MotoRad caps.

Me either. Mine doesn't say crap on it. My brother-in-law suggests that it may be.

Drove it to work today. Kept 195 on the highway. As soon as I hit a damn stoplight temps begin to rise. Circulation issue possibly? Thoughts?...

How high did temps rise to? Normal seems to be about a 10 degree rise due to less moving air flow and water flow at reduced pump speed.

After fixing a coolant leak, filling and bleeding per manual my idle temps would sometimes be +15 or a bit higher somtimes kicking off the electric fan at idle.

Drove 30-50 miles per day, each morning for a week or so while stone cold I removed bleed screw and topped off via the bleed fitting using a small funnel. First morning may have added 8 oz and amount decreased each day until air fully displaced by coolant. It did take a week of a few minutes per day but didn't need to keep removing reservoir, wasting coolant flowing out of bleed and making a mess. Low speed/idle temp rise gradually settle to acceptable level. May help doing the same?

It may have hit 201.. was busy watching traffic for an opening.

It is confusing to me about the temps, especially with that stat in it. The only parts of the cooling system that I have not replaced are the heater core, and pressure tank.

What's wrong with that, only +6 from the 195 you reported? Maybe you should just forget about what stat you have since that seems to be what is puzzling you. If not overheating chill & enjoy the ride.

I'd love to.. if it didn't begin meltdown at idle. That alone means there is something wrong. I have a difficult time with that. Basically I can live with bad lock actuators. Not erratic temps. Lol
