I'm siding with @Ronnie.
I went to a radiator shop, they actually work on radiators not just sell them. The sales guy gave me 3 choices.
1) new copper/brass, $700
2) recore, reuse my tanks $650
3) a new aluminum one. $475
A couple of things concerned me during the conversation.
1) He ask if I had a 2 or 3 core radiator, I said 4 he looked surprise; When I look in the filler I see 4 rows of tubes front to back. So I'm guessing that my answer is correct but why would he be surprised
a) am I wrong
b) is four common for our E350 buses
could it be that a "regular e350 has 3 but in the school bus version they use 4 cores. I didn't mention it was a school bus only that it was a diesel. I'm just trying to give fewer reasons to run the price up
c) did someone upgrade over the years
How many cores are common
2) The new aluminum was quoted as cheaper but is it better.
a)Would it be as big and does it need to be as big
b)Would it have all the same ports. This radiator has an extra port on the bottom for a line from the heater. Does a new aluminum one have that port
I sensed that either he didn't know or wouldn't make a statement to such things. Since I'm doing the remove and replace he really does care.
I wonder, do all 1992 E350 have a 4 core radiator with extra port for the heater
3) I thought aluminum Radiators were more expensive that copper/brass.
Did I get a good quote for the what i need?
