Radiator replacement
My radiator has started to leak pretty severely at higher temps. I am planning on pulling it out this weekend. My questions are:
Has anyone else done this on a 2000 gen and have tips?
Is it worth trying to get it repaired or should I just put in a new one?
On my 2000 are the oil lines and the transmission lines the only things I have to worry about, or does the A/C run through there?
150k mi
thanks

Re: Radiator replacement
Unless you have a dunk tank and a means of pressurizing the radiator, it's cheaper to get a replacement rad.

Re: Radiator replacement
I did the replacement on a 1995 with the new front end and it was very easy. Remove the upper rad shroud, then the lower one. You then need to remove the grill. (You will need to remove the signal lights to get to 4 screws for the grill) The condenser mount screws need to be removed from the radiator and then the radiator can be removed after disconnecting the lines.
I would look to the HD radiator upgrade stickied here or just buy a new one. They are pretty cheap.

Re: Radiator replacement
Welcome to the board, nice to have you here.
As for the radiator, no problem. You can do this. As mentioned, remove the grille. You'll be surprised at how easy it comes off. No a/c lines to worry about and as for the oil and tranny cooler lines, again they remove strikingly easy.
TIPS (while you're in there anyway):
Replace the oil cooler rubber lines. See the sticky with pictures for this.
Add additional external tranny cooler. It's cheap and easy and does wonders for the trans. See the sticky with pictures for this.
Replace the hoses, stat, and belt. You may want to consider the belt tensioner as well. Mine came apart a few years back for no reason.
God bless

Re: Radiator replacement
thanks for the tips!
I have decided to replace the water pump (orig 150k), thermostat and hoses while I am at it. So with the new radiator should i use one of those stop leak products when I refill? If so which one?

Re: Radiator replacement
Do not use any additives to the system. They may block up the cooling passages in the engine. Just refill with fresh coolant to the proper mix.

Re: Radiator replacement
The job went really smooth. I replaced the radiator, waterpump, thermostat and some hoses, and it only took one full day with a couple trips to the parts store. I did have a 2 inch crack in the plastic side part of the radiator. Waterpump wasnt leaking, but with 150k on it I figured i should do it anyway.
So after all this, the running temp seems to max out just below 210 on the dash gauge. Thats just a bit hotter than before the work. is that a normal temp?
also I am curious about the trans cooler mods. does anyone have job pics?

Look in the transmission section. There is a stickied thread about just trans coolers.safari2000 wrote:also I am curious about the trans cooler mods. does anyone have job pics?

Re: Radiator replacement
That sounds hot to me. I run a lot cooler, more like 170, but I have a 180* Tstat installed and it has been great so far, only about 900 miles on it, gas mileage seemingly increased.safari2000 wrote:So after all this, the running temp seems to max out just below 210 on the dash gauge.

Re: Radiator replacement
Thermostat is supposed to be a 195º. Dash gauges are inaccurate, so it sounds about right.

Re: Radiator replacement
I knew I shouldn't have read this thread! Now my radiator is leaking.
We're heading to Yosemite this coming Tuesday and with shipping, I won't get the $100 ebay special here in time and a radiator at the local store is at least twice as much.
I'm going to drop a few sealant tablets in and hope it holds together for the trip. It's leaking on the driver's side somewhere; consistent, but minor. After the long and hot haul from AZ earlier this week, I never even topped it off in spite of the leak.

Re: Radiator replacement
Well I cheated and won. I bought the radiator tablets and dropped only two of the six they recommend into the radiator and swapped rad caps to a low 7lb cap... not a single leak on my whole 800 mile vacation.
I swapped back to the 16lb cap and all is still good. I guess I'll run this rad just a bit longer.

Re: Radiator replacement
yup, started leaking again, must have been the 16lb cap I reinstalled, it's just too much. I'll be starting the rad swap soon...
