I was driving in the snow two nights ago. The snow was over a foot and was like sugar, not light and fluffy. The temp was normal than shot up to the top in 30 seconds. I had this happen once in deep sand. It was cold out as well. My guess is Thermostat? Any ideas? | ||

could be thermostat, or you are packing your radiator tight with snow and or sand... | ||

FWIW, I have seen this caused by lack of antifreeze in the radiator, the water will freeze and not be able to circulate | ||

Whoo Boy! I hope you stopped before it got hot enough to drop the valve guides from their bores! You may have had a situation where the coolant in the block got hot and boiled away because the water in the radiator was frozen solid. Been there, done that and have the wounds from my wife, the receipts for the cylinder head rebuild and, I even took a few pictures! For your sake, I really hope it isn't this as mine did catastrophic damage in about 10 miles of driving! First thing to do is to check the coolant. | ||

Coolant levels were fine, everything was clear of snow, and I'd been driving for over an hour. After it cooled down (10 minutes), I drove for another 20 minutes before it quickly raced up. It's not slowly heating up, just all of a sudden. The expansion tank was bubbling a little. Seemed to start the rise while going up hill. | ||

OK, the level is fine, but what about the glycol concentration? With your comment about the temperature rising upon application of greater load, you are exhibiting classic symptoms of a clogged radiator. How many miles, what year truck? | ||

paul has proberly solved your issue, the lack of proper coolant/anti-freeze mixture added to the low tempature (including the chill factor) proberly froze some of the fluid in your radiator reducing if not stopping the fluid flow. this leads to the overheating. how was temp inside of your cab? if it was cold inside the cab and the temp gage was reading hot you have little to no coolant flow. this is bad. also, the accumulation of snow and ice on the front grill work can restrict the flow of air across the radiator, but i don't think that was your problem unless it was packed solid. best of luck! mike w | ||

I had similar symptoms. Replaced the temp sensor and thermost to no avail. It turned out to be a clogged radiator. A local radiator shop replaced the core for $300. It hasn't overheated since. Based on the number of people that post this question and from experience, I'd say this is a common problem on Rovers. Good luck... | ||

Jimmy: With luck, all you will need is a radiator. At 177K, you need a radiator. Paul | ||

I have yet to hear anyone say that when you replace water/antifreeze, never, NEVER use tap water, ALWAYS use distilled water, this way you're not adding minerals to your cooling system, or oxygen for that matter, and it does matter!!! Peter. | ||

With luck...it is not the radiator! It was just the thermostat. I'm 99% sure it is my thermostat because of the signs. I'll know Monday. I agree with the distilled water thought from Peter. There is no need to replace a radiator if you take care of it! |
