Consider a broken blade on the water pump, that fell off and is lodged somewhere. That worst case. This happened to a guy who got it out by removing the drain bolt on the block.

Consider a bad thermostat, as you have already. Cheap and easy to replace at $20.

I do the FDM (fan delete mod) here in Northern CA without issue, but 90 degrees it the most I ever see.

sure it's 160-260?? I didnt think it was that wide..

and completely agree that FDM is worth it with the proper supporting mods,

Hawaii weather 90+ in the summer, and hot all year around, in major traffic and zero issues...

Status update.

I pulled the water pump out, and it was A-OK the bearings felt good, the blades were in good shape, so i replace it anyways

I pulled the T-stat, it looked okay, but again i replaced it anyways and all is well, drove the car for a while tonight and let it idle for a while. She stayed cool as a cucumber.

Thanks for all the help!

thermo can "appear" to be good, but be bad under heat conditions....

glad it's working out....

good bleed I'm assuming?

Preventative maintanance on the water pump is never bad

I love the guys that think the stock fan is good for anything other than pulling some air through the radiator at walking speeds or less. (it doesn't)

The stock gauge stays in the middle from 130F to about 225F (in my car)

Fan delete on my car for 6 years with no issues. Ideling at Dulles airport in 110 heat, ac on. 210F! If it goes higher than that, you have a problem.

Richard and Cal, you guys help further my decision to go ahead with the FDM. I bought the kit but have it sitting because I want to find radiator I don't have to zip tie my coolant reservoir too.

What have u guys done, I know i've seen pics of yours somewhere in a thread Calvin. How did u mount yours? I was going to get Euro reservoir to put by diagnostic port.

If i remeber what cal said in an earlier post to me, he has the same zionsville comp radiator i do. That radiator kit has a metal expansion tank that is bolted to it.

for example

Sorry. Not sure about the 160-260 range. I read that on this forum somewhere.

i do have the same one. Mine is mounted to the radiator. Just make sure you have the fan coolant sensor plugged in properly (this is vital)

and yeah, the Euro reservoir would be perfect for what you need

okay, so here we are morning of day 2 after the fix and when the car is turned off, it is still puking coolant from the expansion tank

the hoses start gurgling and coolant comes out of the pressure release hose, as if the cap is not holding pressure. Has anyone with a stant coolant cap ever had a problem with the cap not holding pressure?
