...........If you have a brass radiator, one thing to consider is replacing it with aluminum. Might not last as long, but they cool better. Even the cheap junky TYC.
Thought I might add a thought or two. In the 20 or so yrs that I've owned my '94, which came stock with a brass radiator, after fiddling with all the cooling system components you've mentioned, plus a few more - the biggest positive difference was adding my "cheap junky TYC radiator". I might add that it was a suggestion from Kevin (Tools R US) if anyone else considers his advice to have been helpful. Oh, and he also mentioned a time or two that the TYC outperformed any of the 80 series OEM aluminum radiators which were stock in the '95-'97's.Since getting my truck eight months ago I've been through a fair bit of the cooling system.
I'm seeing temps of about 185º-190º around town at slow speeds and usually a solid lock around 179º on the highway (ambient temps up to 80º or so.)
- PHH
- Thermostat
- Radiator Hoses
- Blue hub fan clutch from Wit's End
- Flushed it all w/ the PHH install
Was rockcrawling this past weekend--sunny and about 75º--and hit my Scangauge alarm of 205º--dropped back down under 200º once I got above 3mph.
The factory manual suggests I'm OK but I've seen people here say they see 170's around town...am I leaving cooling on the table? I know I've seen threads with people comparing temps but couldn't surface them in a quick search.
