Beating an overheated horse

[Frobisher]

I think OP's Disco is long gone.

As one last kick on the dead horse, a new decent aluminum radiator is way better than a 25 year old copper one. The cost of restoring a copper unit isn't cheap either.

Not to jinx myself, but I have swapped a myriad of aluminum radiators in Rovers with consistent results. I've also seen a couple doughy pot aluminum ones for Jeeps. Some Chinese make impressive (for the cost) units, others you wonder why they even put it on a boat.

Yes, it’s gone to Death Rowver on my buddy’s property where it’s freely offering up its vitals to my replacement ’97. Parts are still available if you need something from a ‘95. I won’t using everything.

The follow-ups here have been enlightening, so I’m happy to see it going.

Sorry for the thread Necro, But I was having heat issues forever! Changed over to the 82c (180F) Deg thermostat. In the 100f summer temp I would run in the high 190"s-200 area. I switched to the FlowKooler waterpump In Feb when mine went out. this summer in the 110F temp it was setting at a solid 181F. This pump rocks and well worth the money. I'm going to be switching to the 88c to get the temp range to where its supposed to be.

I too put one of these on this year. They are impressive. I didn't switch because I was having cooling issues, but because the original one was making a little noise had some resistance when spun by hand.

OK, I'm jumping in on this resurrected thread. I have an '04 D2 with original 4.6. What's the ideal temp range? When driving on the highway, mine will usually stay between 190 - 195F. The other day in heavy traffic, hot & humid day, waiting at stop lights, it hit 210. For context, I replaced all coolant system hoses, water pump (OEM style), and thermostat last year. I also replaced the head gaskets last fall, which is why I want to make sure I'm keep this thing running at the right temp. Thanks.

I'm in Arizona, that's pretty normal temps here with the AC on.. The first place to start with high temps is the fan clutch IMO.. I've had to even lock that clutch up on a trail before, until I replaced it.. NOW, the fan sounds like a JET all the time!

The 2004 D2 ideal engine temperature is room temperature.

A quick word of advice for those with older D1's: I recommend gettin your copper radiator boiled out (and rodded if necessary afterward) rather than buying a cheap aluminum replacement. Aluminum looks...cool, but copper is almost 2x better at shedding heat. You can tell your radiator needs to be boiled out your engine gets hot (on the freeway) a few minutes after turning on your AC.

+1 on the flowcooler. It has noticeably helped.
