Re: Followup-- 2000 JGC V-8 still overheating
Hi James,
If your coolant stayed in for more than the recommended time, sediment would attach to the core, that only a rod out would fix.

IF the clutch fan started to engage at 65 or 75, you would know it unless you have a very loud stereo or exhaust system. Many years ago I had a over heating problem with a old Jeep truck in the winter plowing snow but only when transporting, not when plowing. . It turned out the between the cold air temps preventing thermostatci clutch fan from engaging (it is based on air temp coming thru core not coolant temp) and disrupted flow of air from plow at speed the truck would start to slow cook and get pretty hot. The cure was a more agressive clutch fan setting. Not say this is for sure your problem but when you stuff a big engine in a little compartment you can have cooling issues sometimes because ram air does not always cut it. If you get guage hot and stop and idle does clutch fan engage then? ----------------- TheSnoMan.com |

He could try raise hood starting car up with cap removed and a blanket over front end to allow it to heat up and not cool coolant and watch for agressive flow in raditor. Also replace cap and let it get hot at about a 1000 to 1200 RPM fast idle and see if the clutch fan every engages and if so at what temps on gage ----------------- TheSnoMan.com |
