coolant temps,again!
my 97 d1 with 110k has had all fairly new parts,[rad,water pump,t-stat,hoses,sensor,coolant,hyper-lube] normal driving short distances it barely gets to the t-stat temp of 195[oe] then runs in the 199 to 206 rang,after stops sitting in 85-90 temps climbs to 212 to 221,224.today i drove about 80 miles at 65 to 70 and the temp ran 206 til some traffic up to 212 and stayed there,after more stops sitting i watched my scan gauge creep to 224,228 at it's high but after moving again came down to 219,221.that's with ac on [also have 2 10" fans are fairly new] truck ran beautiful,my question is once t-stat is open and highway running with a new water pump could the circulation be so fast that the coolant doesn't sit to long anywhere so temps remain higher?[once it is already hot] and when i shut her down at 215-219-221 the fans never came on,are they supposed to at those temps?thanks in advance to those who respond with opinions,oh i did put a bottle of at-205 in it and maybe it thinned oil [20-50 pennzoil change every 3 mo] and hood liner [original] is sagging[maybe?adds to trapping heat] opinions welcome

Have you replaced the fan clutch?
|
yes,maybe a year old,and hard to turn when off so it's good
|
did you test the stat before you installed it
could try a lower 88C stat |
no but bought from ab and it does seem to work because it takes awhile for truck to get up to temp and for short hops runs around 199-206,it's only after coolant gets hot that it tends to run hotter but for the most part it stays under 212
|
what kind/brand of Radiator did you put in?
|
it's the all metal original from british rovers here in s. florida,no leaks either
|
your temps arent to far out of line from mine with a 180F Tstat. when I had a 4 core all aluminum rad. - that was almost a year ago.
especially with AC and stop and go |
i just remember reading the thread about 230 turn off ac,240 your lucky you know cause at 250 ya got a boat anchor!!! what temp do the front fans turn on [after shutting truck off at 220degrees] cause they never came on
|
yeah I have read alot of 'watch out for' too but I monitored mine for a while and they never went above 228 but hovered around 205 IIRC.
I thought I saw in a thread it was 212 the A/C fans came on or maybe 220 but I dont recall mine ever coming on during that period I was monitoring it. |
