Hi!
I'm cleaning up a 1989 colony park for my sister; we've put nearly a thousand into parts....
Anyway!
I'm doing the coolant hoses RIGHT NOW. All of 'em.
Now, there's a long one that goes from the thermostat housing back to the heater core.
OEM has 2 hoses with a restrictor in it.
New from NAPA is just one hose.
Do I want to slice that hose and install the restrictor?
Or, leaving it out, might we actually get more heat out of the heater core?
The risk as I've read is that the heater core can blow.
Does it matter which direction the little restrictor faces (I didn't keep track when I cut the old hoses off)?
My sister is a lead-foot, but, there will be no modifications to this engine and it will rarely see the high side of 3000rpm and never the far side of 4000rpm, if my own colony park with its tachometer on it is any comparison. Granted, she's got the 3.55 rear... for just 2 more days ;-)
So if she's going to get more heat with the straight hose and it's unlikely she'll blow the heater core... versus, if even 3000rpm can be a danger to an antique heater core without the restrictor, and I really ought to put that in there.
Let me know ASAP! Like in the next hour-two. Gonna go do the 2nd O2 sensor and spark plugs while I wait for your advice
