'94 Loyale overheating on freeway
Posted 31 August 2006 - 04:52 PM
The garage does a coolant check, I told em to go ahead and swap out the thermostat. The electric fan is coming on. And when sitting at idle in the garage, it's not acting up. I pull out on the freeway and it's hot again.
So here's what I've gathered:
- Not noticably hot in idle or up to 40mph.
- Heats up to 3/4 or red line at 50+mph.
- It seems to cool slightly or at least manage itself through air cooling, e.g., going down hill the temp eases a tad.
- Engine strain while going up hill increase the temp to red line but it will cool slightly again on the down hill.
- I can continue this for over an hour or two without actually red lining but remaining above 3/4.
- Electric fan is fine
- Coolant levels and oil is fine
- Don't know condition of the radiator yet
I had to ditch the car at my families house in order to immediately get back home and to work. They're helping out but it's all going to be through an unknown garage.

The entire radiator should be a fairly uniform temperature. If there are significantly cooler spots, you've got a clogged/bad radiator.
The good news is that a brand new radiator for an EA82 is only $90 or so, and about a 20-30 minute install.

Really does sound like the radiator. If you flushed it, yourself, with chemicals from a parts store, sometimes they loosen up some sludge, but then it gets stopped up somewhere else. ONLY way to really clean a radiator, is to remove & take to a shop.
