How difficult will the swap be? I mean pulling the engine
I have an M73N from a 2000... in Kansas.
Got quoted $2200 for labor to rebuild the engine. Plus the cost of the new gaskets and seals
HG failure when overheated is fairly rare, especially compared to say the M54 I6.
I'd take the risk. Reseal the intake manifold, new WP, and do the ignition components. Does it come with a transmission as well?
That's why you use a sealant (renzosil) instead.

Weird! So today I decided to put the car on ramps and top off coolant, and replace the extension tank cap and made sure i dont close it too tight. Filled up until coolant start to come out of the bleeder screw.
After few bubbles out, i started the car and opened the screw at different interval. I was getting less and less bubbles until it was all coolant coming out.
Took it for a ride and coolant temp stay between 108-110. Mostly 108 if i I keep constant acceleration. Its got to 111 couple times while at a red light but if I put it in neutral and rav to about 2500-3000 rpm it then goes down to 107. it goes to 110 When accelerating to take off or when I accelerate hard, then it goes back to 108 when cruising.
Was afraid to take it on the high way.
Now am confused with the blue combustion test I did 2 days ago. Either the test was wrong or the Bar's stuff is working.
Probably due to the earlier contamination of the coolant, but was there the same amount of bubbling in the new test-after the Bar's?
No..less bubbles..and when bleeding i got to a point it was mostly coolant coming out of bleeder screw...
Was over tightning the extension tank cap until after reading not to tight it too much. So replaced cap and tight it just a bit
Also i dont hear water circulating inside while driving.
You were actually hearing the turbulence in the coolant, caused by the air!
Less bubbles is a good sign, it means the Bar's working.
