Friends: 1 |  Too Early to 100% Grill Block? Just got done blocking the lower grill (upper was already blocked), but I held out on blocking the last lowest slat on the lower grill because I wasn't sure if it's still too warm out to do a 100% grill block. My morning commute is in the lower to mid 30's and my afternoon commute might get up to the lower to mid 40's. I do have a SGII to monitor coolant temps. I'm lucky if I see 160 F by the time a reach work (10 miles one way, stop and go, no highway). Should I go ahead with 100%? I saw someone post on the forum that monitoring the Inverter temp is important. Is that possible with my SGII? Do I even need to worry about it? |

Friends: 0 | Re: Too Early to 100% Grill Block? You can run fully blocked at up to 20C or 70F ambient. It's actually safe above that (I've run on the highway fully blocked at ambient temps of +30C (80F). The highway is where the engine gets the warmest. I saw max. coolant of 95C in those conditions. Perfectly safe. The car was able to drop the temp quickly when it tried to climb. Inverter temp isn't available yet from the Scangauge. It runs a lot cooler than the coolant anyway, so I don't worry about it. |

Friends: 3 | Re: Too Early to 100% Grill Block? I run fully blocked this time of year, except I went ahead and cut my lowest two blocks about an inch shorter on the inverter side. I will probably stay fully blocked until about mid to late March. |

Friends: 6 | Re: Too Early to 100% Grill Block? I have everything except the lowest slot blocked and it was working great - until the warm spell this weekend. 68F ambient temp and as I was coming out of the tunnel and going up onto the Zakim bridge I glanced at the SG - 202F  . So I threw on the heat and fan and it took it down to 188. Shut it off, and it went right back up again, so I opened the windows with the heat on. But alas - it's back down in the 30's again, so I will need to block the last slat soon. It wouldn't have been a problem if I wasn't pushing the engine to keep up with  Boston traffic.
