Coolant leak on a 3rz-fe

Hey guys,

I was performing the regular 5000km service for my 90 and I realized the coolant container was bone dry. Previous to this I noticed it was consuming a little but it wasnt as alarming as this. When I removed the protection plate to change the front diff's oil I found that there was coolant residue on it, and all over the oil pan on its right hand side. I couldn't find the source of the leak but I know its in there somewhere, any ideas?

Now, is this common?? What should I be looking for?? the car has only 55000km.

Is it common for the car to consume ANY coolant?? What coolant should I use when i fix this?? any tips??

Thank you in advance for your replies,

Cheers,

Luis.

I found it, after inspecting every line from the cooling system I found that it was the water pump which was leaking coolant, it needed replacing. I found it odd that it was leaking at only 56000km. But, oh well, new pump and that is i (although it was the most expensive scenario..)

Feel free to delete this thread,

Cheers,

Luis.

Be sure to also check the radiator for swelling. They seem to have a tendency to do this once they've overheated with low coolant. From the top, look straight down the radiator - the core ribs will be dead straight in the middle, but if it has swollen, the outer ribs will be curved outwards. This will cause pressure loss (high temps) and potentially coolant loss if the damage is significant.

Hmm, this would happen even if the car never raised temps??? I mean, it never overheated or did the needle go past halfway on the temp gauge, it always sat on normal temps.

Thanks for your reply
