Radiator cooling troubles

[Spacehulk]

Hi all

Got a radiator question. Ive got 66 mustang 289 v8 and i think the radiator is clogged. Im going to try and flush it myself with the diy tools available but was wondering what are reasonable radiator brand names

Are the ebay aliminium ones real bad quality? Any recommendations on radiator shops in melb?

So far Ive cleaned out the water and have replaced with new coolant. What it does is, after it gets to temp or driving for awhile the temp gauge almost goes off the dial and blows out coolant.

What have i done, so far replaced a faulty thermostat and replaced coolant, water pump was replaced a year or two ago. I also bled/burped the air out of system by runing till there are no bubbles, but when it heats up it seems there is not enuff flow thru radiator as it overflows. Any ideas or recommendations would be appreciated. Currently have a two row.

Cheers
Martin

I've had a $200 eBay cheapy in the GT (warm 351 Clevo) for about 3 years now without failure. Maybe it doesn't cool to the level of the more credible brands, but it's good enough for a tight budget.

Original copper radiator?

Take it to a radiator shop and get them to clean it out or recore.

You could get a cheap IR thermometer and check the radiator in different locations and that will assist in determining whether the tubes are blocked.

My opinion is that for stock or near stock, then leave the original system in place with the correct factory fan and shroud if they had one.

Cracked head. cracked block or dud head gasket, only showing at temp?

If the radiator cap is not holding pressure at all, or can't hold enough pressure, the coolant boils and steam blows it all out (particularly this time of year). Glycol doesn't change the boiling point much, its mostly the pressure that stops coolant from boiling.
