High coolant temp - ZR-1 Net Registry Forums

secondchance · 06-20-2010

I replaced my radiator (OEM) about 5 years ago and installed Marc's chip about a year ago and she had been running at around 213 - 215.
Last week in 90 degree weather in rush hour traffic I noticed temp gauge hitting 230. So, I turned off the AC and temp came down to 213 and as I drove home.
Yesterday (90 degree day), driving back from the body shop (yes, I got her back and she looks perfect!), driving 65 mph, temp was a 225. Normally, 65 in 6th gear use to be around 213 and a little cooler in 5th (better coolant flow I figured).
I will check for any debris on the front of the radiator and fans (been busy).
Anyone had a similar experience?
