Replacing coolant/ ECT code

I agree with with 2in. You've gotten every single idea out there short of pulling and replacing parts peice by piece. The only other thing you could do is bypass the heater pump with hose barbs and hose to see if the issue goes away. You're spending more time chasing it down than if you had taken it to the dealer a couple weeks ago.

I agree with all of you 100%…….

BUT! I found the fkkkkker.

Part of the issue has been that for some odd reason I cannot disengage the transmission so I can only run idle on the hose at home.

So we get to the lake today and all the above holds true.

I told my wife let’s just take it off the trailer and drive a bit to see if I can find the leak and keep an eye on engine temps (never rose above 180).

At any rate. I have noticed my heater pump hasn’t been running. My next step is to either replace it or look for why it’s not working.

So, after chasing ALL connections and ALL suggestions and possibilities, it’s the actual damn heater pump that’s leaking!

If I hadn’t driven at higher rpms today I wouldn’t have found it.

Now I’m just going to get a barb and bypass at the pump connection if I can’t get it running or a replacement ASAP.

I think this has been happening for a while since we haven’t used the heater in months and I’m REALLY low on coolant. After the bypass or fix I’m going to do continue to top off and will do a coolant exchange per protocol at end of season along with everything else.

I can’t thank y’all enough for helping me with this. If there a silver lining I hope some of you learned a few things from my troubles!

Thanks again!!

This is so minor compared to the guy on the Supra forum who blew up the #3 piston on his 2020 SL550 and Indmar rejected his warranty claim due to water found in fuel.

$25k-$40k to replace

You guys are killing me and a bunch of a$$holes! Hahahaha.

I appreciate the sarcasm, comedy, and above everything, all the help and support I received.

There is a saying in manufacturing...."If they are not giving you a hard time then they do not like you!" Take it a compliment....LOL

Good to see you found it and can go back to enjoying the rest of the season. If warranty would cover it, get that done this winter.
