What is your coolant temperature at cruise?

[iangoround]

I'm just curious as to what everyone is seeing for a coolant temp at cruise. I had a chance to take my turbo z out for a spin for the first time since putting in a new gauge cluster and TU radiator. Eith a 180 degree thermostat and 42 degree air temp, it settled in around 210 after about 15 minutes of highway cruise. I'm wondering if I need to make some baffling to go in on the sides of the radiator to force air through it better.

That's horrible.

That's horrible.

Agreed. cruising at freeway speed it should be darn near 180* at that ambient temp.

With a 195* thermostat that has a .042 hole drilled in it, my temp sits right at 185 on the highway. Thats on a van with the radiator moved to a non ideal location with lots of holes for air to leak around it.

Van has a much larger grill than a daytona. All the shrouding needs to be around the rad to force air through it. Also need at least the factory air dam installed. Also the splash shields in the fenders need to be in there as well to help with radiator efficiency.

That's what I thought. I guess after I figure out the smokescreen I get at hot idle after a drive, I'll reinstall all the shrouding and try it again. I'm hoping its airflow at cruise that keeps it warm. When I'm stopped and the fan kicks in it cools off to 180 pretty quickly.

With a 180* t-stat, my Lebaron will sit at around 175-180. I have the large radiator.

I found and installed the plastic bits above the headlights. Coolant temps now hang around 185 on the highway. Much better.

The old Earl's plumbing catalogs used to have some good tech info regarding sizing of heat exchangers and the effects of placement and air velocity through the cooler, I recall being quite surprised just how much velocity aided cooling ...
