Engine Over Heating Solved

[89 MAUI]

Having had the problem of transmission cooling lines that were rusted and leaking.  I had custom made cooling lines made since replacement cooling lines were not available anywhere.  I made the decision to replace the radiator while I was into this project.  While into this project I found that the transmission fluid had not been replaced in many years so I took it to a tranny shop to replace the fluid, filter and gasket. 

 

I brought it home on Tuesday and today I took it out for a 45 mile drive of highway and 40 mph roads and found that the engine temp never rose any higher that 192 degrees and that is with a 190 degree thermostat.  Having had the Reatta for 6 years I was always seeing 210 to 225 degrees on the thermo with combined driving, but now I am very pleased with replacing the radiator.  The old radiator must have had a lot of clog in it.

 

A new radiator runs $100 in the ROJ Amazon store and it may be the answer to controlling the temperature of your engine.  Replacing the radiator looks very involved but once you start it is really quite easy. :)

Sounds like your time and money were well spent. I will keep what you did in mind if I ever have a problem with my engine running too hot. Thanks for posting!
