I'm having an overheating problem.. Just took her out on the interstate for her first long trip and it seems if I go over 55 it wants to overheat. If I slow down the gauge drops and everything is fine. Ir does great around town. obviously I checked the antifreeze, and the cooling fan does run too. What could it be!?

1. Check thermostat. Remove it, throw it in a pan of water on the stove. Use an old, crummy pan or the lady of the house will come after you with a rolling pin. Thermostat should be fully opened before the water starts boiling. If it doesn't open in time, time for a new thermostat.

2. If thermostat does not fix the problem, it's probably time for a new radiator. Radiators are not expensive, and I've come to the conclusion that a new radiator is fairly cheap insurance for an older car.

I was leaning towards t stat too, heck with testing it I'll just put one in it tomorrow, seems to be doing better right now, I'm about 100 miles into the trip and I'm cruising around 60 with the gauge in the center, srising after that, is there any options for an oversize rad?

I think what BR meant to say is that an oversize rad is just the last thing you need on a Metro. In reasonable condition the stock cooling system will cope with any climate. They just don't overheat unless something is wrong.

Rudolph had the exact same problem. After a new t-stat, and a flush, and a new radator and he was good to go! :thumb

The way I see it, if you can get an oversized radiator, go for it. We desert folks always want more cooling capacity. Thing is...I've never seen an oversize radiator for a Metro.

Swift radiators are two row, have more capacity. There's no need for it whatsoever though, they'll usually run just fine with the stock radiator and the grill blocked off for mileage, there's plenty of cooling for a well running engine.

As has been said, you've most likely got a clogged radiator. Also check the bottom hose, sometimes they get mushy and the suction from the water pump causes it to collapse, blocking the flow.

I too vote for a clogged radiator. I've had several temp sensors go bad for the fan circuit over the years and the behavior is the opposite of what you describe - cool on the freeway and hot in town...
