You don't need multiple holes in a thermostat. A 3/8th hole in the TOP of it can work well. I am not a fan of ever removing a thermostat. One of their purposes is to restrict flow so the coolant is pushed up against the water jackets.
Think of it like this. If you poured water onto a BBQ hotplate, the water would "bead" into tiny balls restricting heat transfer. If you to push the water onto the hotplate, it would transfer heat better with a much better surface area. |
To keep coolant pressure in the coolant gallery, with or without thermostat, make a restrictor for top hose after thermostat housing. Check Gojeep's site for info. Regards oldon.

Just thought I'd interject here. In regards to pressure cleaning the condenser etc, be careful not to use too much pressure. The fins, especially if old, can bend easily. Virtually blocking off all air flow. This will make your situation worse. Just a fyi. Cheers Sent from my FRED |

As for running without a thermostat, I never recommend this for "normal" use but for a test it's fine, especially now that we are into the warmer months, if the temps run lower without a thermostat then it will show that there is a problem with the t/stat, I've had issues with aftermarket t/stats which is why I run an OEM unit... |
Well I pulled the grill out and pressure washed the air con rad and tranny cooler the didn't look like they were all blocked up but after washing on spray which did not hurt them I started the car and turned the aircon on and could feel the change in air pressure created by the fans so I assume if I can feel that air should be able to pass through at highway speeds
anyway it cant hurt EDIT Hours Later After power washing the air cond rad and posting I got thinking if the airflow is restricted the new rad isn't getting air fans are only sucking hot air trapped between the rads I wasv looking at my aircon rad and its big coveres the new rad behind it ok I washed it and felt the fans like I said above BUT! if you look at your rad tranny cooler the fins are wider than the standard aircon rad realy close fins what I thougt I might try is to get a metal nail file and every 3rd of 4th fin stick it through thus creating a real hole for air to get to the engine rad you might squish a fin here n there but there would more air getting through opinions I think it cant hurt as I am not a big aircon user secondly thanks oldon this guy is a interesting read gojeep http://go.jeep-xj.info/ anyway I am going to have a closer look at the aircon rad tomorrow and see if I can squeeze a nail file in |
