Re: 454 P30 radiator removal raffy 10-23-08  
Hello, i owned a 1984 Chevy Midas 454 engine/ 7.4 liter gas Class A motorhome and by any chance I want to know what kind of chasis does the radiator sit on. I've been calling different radiator places and they're asking me that question. Also, is the any comparable vehicle or trucks that i can compare my RV since it's an older one? Thanks

Folks this may be one reason our copper radiators are failing today.

We are eating our copper/brass based radiators alive it seems with the orange antifreeze. My previous owner ran the Orange coolant. I am glad I got a new water pump since it eat the impeller as well.

My motorhome is in Las Vegas away from my shop. I have a split radiator on the drivers side. If I have a 1985 Cross flow radiator, can it be removed without jacking the front end?

On a 1987 MH, you're not going to want to spend a lot of money, but you ought to be able to do it yourself, if you've got a decent set of tools.
I believe you have a crossflow radiator from 1985 up, so the front end doesn't have to jacked up nearly so high as with the older vertical radiator. You can unbolt the AC condenser and/or external engine/transmission oil coolers, so you shouldn't have to reservice the AC. On the back side of the radiator, you will also need to unbolt the radiator fan shroud and the fan and disconnect the transmission and oil cooler lines from the radiator tanks, and then unbolt the radiator, which should slide right out the bottom just forward of the crossmember.
TIP: While you have the coolant drained, it would be a good idea to check to decide whether you should replace the water pump -- at least change the little rubber bypass hose between the back of the water pump and the front of the intake manifold.
If you've got at least 50K on the engine, I'd recommend replacing the timing chain while the radiator was out, too, since you will have most of the work already done to get to it. And I'd also replace all of the belts and hoses, too. Save your old belts and carry them for spares.
Don't try to skimp on coolant. Replace it with a 50/50 mixture of antifreeze and water.

Removal of radiator from 1984 midas 454 chevy
Re: 454 P30 radiator removal Ducky 5-16-10  
I too may be replacing my radiator soon, as I am still not comfortable with the running temperature of the engine. I have a 1983 Southwind J27, with a 454 on a Chevrolet P 30 chassis. When I purchased it, it was running at 225 degrees. After surveying the situation, I discovered that the water pump and the thermostat and most of the hoses were original. I also noticed that the aluminum mounting bracket which supports the a/c compressor was broken.

I replaced the long water pump with a new one, and replaced the 195 degree thermostat with a 180 degree thermostat. I flushed it, and added a 50/50 mix, and even though it now runs at 205 instead of 225, I would like it to run even cooler.

I was able to locate a steel a/c mounting bracket from Alan Grove Components for $87.50. But I may have to replace the compressor.
