My coolant light turned on again, level was a little low, no signs of leaking. So I'm happy to report that I replaced Thermostat, Water Pump, ET, and bleeder hose.

Mango wins.

Re: Who else still has the original cooling system?

Just shy of 150k and all I have done is the lower hose and temp sensor in it at 100k. Just got a code for the thermostat last week. So I have been monitoring it, and indeed it is running cool.. Time to replace that and the water pump.

cooling system

mine goes under the knife today for a slow coolant leak. Pretty sure it's just the expansion tank. 120,000 miles.

Definitely do the expansion tank too, it's a more common failure point than the Thermostat. The thermostat might be throwing codes, but it won't cause your car to run out of coolant while driving.

I was driving my dad's e39 when his ET exploded, it was a terrible experience. I was at the U of MN (can't park inside anywhere) and it was one of those -20 degree days.

Well car is getting new front right drive axle because of boot being torn, left steering boot and new expanison tank.

Total kill is going to be $733.00. This is when I really wish I had a place to do work. But got to do what you got to do.

I honestly don't even know if mine was overhauled or not I bought the car at 87.4k miles and I'm at 91.1k and my cooling system keeps my car just a tad under the halfway mark on the stock cluster. Is there way to tell if it's been overhauled or not?

I'm at 130K miles(2004 ZHP) with original cooling system. Seems like something I should do soon. Is there any reason it would be less likely to go in the winter vs summer?

I'm in the same situation. Bought the car 2 weeks ago and although I see "Vehicle Serviced" plenty of times out of state per the Carfax, I'm clueless as to what exactly has been serviced. How do you find that out?

Thats good to hear. My ZHP is at 76k and I've been on the fence about doing the overhaul. 130k is impressive, but I'd def. keep the funds available if it does happen.

This is just my own opinion, but I feel like its more likely to occur in the summer with higher temps.

Yes, I still have my original cooling system. It's all sitting under my work bench for emergency spares

That's what I did, and everything sans the radiator were from 2010, OEM parts at that

Temp gauge probably shouldn't be under half way with normal conditions. That could be a sign of a failed thermostat in the open position.

A major contributor to cooling system failures is heat cycling of the "plastic"/composite components, such as the expansion tank. One might argue that the components are more likely to fail in the winter because the heat cycling occurs over a larger range of temperatures and the bottom of the range can be relatively cold.

For example, in the summer your cooling system components might reach a low of 70F once the car has cooled overnight, then heat to operating temperature of ~200F. During a Virginia winter I would imagine the lows could dip into the teens overnight. You are asking the components to get really cold then reach operating temperature within a couple of minutes. I imagine this is a much more stressful condition for your cooling system.
