My ‘09 has the original coupler still. I’ve got a metal coupler ready to swap in when I get the motivation to do it… I should do that soon lol

I wonder if this is MZ BETTY's old car

Heater hoses should last quite a while. I'll typically check periodically to see if they get pressurized/hard (and ensure they don't "balloon" in anyway) after starting the car and then looking at the coolant reservoir and general condition of the radiator itself.

How many miles were you on? And is the radiator/thermostat the originals as well?

Didn't do a damn thing with my Z.

About 125....I rarely check nowadays. Radiator is orig, thermostat might have been replaced, not sure.....I might be confusing it with my G37.

Need replacement every 10 years to be safe as evidenced above. :tiphat:

It blows my mind owners will replace galley gaskets (at substantial cost and time) without even investigating oil pressure values but ignore old belts and hoses.

It takes 15 mins. max, no need to drain down the system etc. I just removed the hose from the high side first, dumped all coolant out of it, replaced with metal, burped the system, and topped off.

You're current sitch is a timebomb and if it goes while on the track like in your avatar it's going to turn the track into an ice skating rink for your and others. :shakes head:

Removed the crap Godzilla Racing driveshaft for VR60 trans. swap as it threw the weight the local driveshaft shop had to swap in due to receiving it from Godzilla out of balance and with much vibration.

Only a few thousand street miles on it and a U-joint was already shot! Shop installed new non-serviceable joints and it balanced within spec. without needing additional weight.

None too happy about the serviceable joints slinging grease all over the undercarriage.

Contacted Godzilla the 2nd time about the balance issue (they ignored me the first) and told me because I altered it (1st go when replacing the balance weight), I'm out of warranty. I hardly consider that altering, it's the same as replacing wheel weights IMO. They've had every excuse in the book including adjusting non adjustable (per FSM) driveline angle.

Even if I were in warranty, the process is to ship it back to them, which would cost more roundtrip than if they simply reimbursed me for the original balance of $75 which I provided an invoice and before and after balance weight pics. Not to mention downtime. No wonder so many small businesses crumble!!

Also, they did mention other customers are having the same issues. :shakes head:

Installed the Vibra-Technics transmission mount. IMO this is the pinnacle for OE NVH while providing much more rigidity. I can "move" the OE mount on the bench with a finger to its max travel point. It's not blown as both in my possession behave the same, it's just a useless noodle. The new mount requires me to lean in much body weight to move it a quarter of an inch!!!

I could also grab trans. tail shaft and move it with one arm while installed in the car, that's no more with the new! I had much fore/aft movement during downshifts and throttle transitions, all of which are 100% gone with the new mount. The caveat, zero additional NVH over OE!! :tup:

I previously tried a Torque Solutions mount which immediately upon startup made the entire interior including the steering wheel vibrate like a massage gun. Couldn't even focus on what was in the rearview mirror. Maybe fine for track dedicated cars but definitely not for spirited street occasional autocross types.

Fair point. I suppose it depends on the car. Many moons ago, I had a S2K that I sold to a buddy. 18 years later, he is still on the original radiator/hoses at 201K miles.

I thought the gallery gasket going bad was a "not likely" scenario that applied to mainly '09 to '12 models? :confused:

So the old coolant doesn't need to be drained/replaced? I figured if replacing the hoses, might as well replace the coolant, radiator, and thermostat.

For metal hoses, is there a way to see if they are pressurized?

Drove the Z around for 30 miles.
