There is coolant on the ground occasionally. How will I know when the intake manifold gasket is leaking
Because they use an orange colored coolant in it.
I have a 1999 blazer. The heater core clogs up about once a year from the Dexcool. Try having it (heater core) flushed and use Prestone (Extended life) instead of Texaco.
I have a 98 Malibu and I know from experience that antifreeze can leak from the intake gasket. It cost me $400 to fix it. At first we thought it was tranny fluid because it was pink, not that! I have Dexcool in my car and that is what was leaking from the intake. Common problem for the 3800 II; GMs` later 3800s have ALUMINUM intakes; I guess they found the problem, yet they didn`t choose to fix the other cars.....bastards...
I did my own personal research on this question, and studied the Supertech Extended Life (5 year/150,000 Mile) Antifreeze bottles stocked at a local WalMart in Austin Texas. I compared them to the bottles of both the Peak and Prestone Long Life brands that were on the shelf next to the SuperTech product. Here's what I observed: 1. The Prestone bottle shape is unique and different than the Peak and SuperTech bottles. 2. The Peak and SuperTech bottle shape is identical. 3. There is a lot number printed near the bottom of each bottle on all the antifreeze bottles I looked at. The Peak and SuperTech bottles had lot numbers that began with a C followed by a long string of numbers, which were nearly identical. The Prestone bottles had a totally different lot number format. 4. Both the Peak Long Life and Supertech Long Life bottles listed the exact same ingredients, including the NJTSRN QT1 mystery ingredient(s) that evidently Peak doesn't want us mortals to know about (It is the same ingredients found in DexCool, which some folks claim will rot the insides of your cooling system!). The Prestone Long Life bottle does not list this mystery ingredient. Here in Texas, I would bet that the SuperTech Extended Life antifreeze is currently supplied by Peak. Could be a different story in other regions of the country, but do a little investigative research at your local WalMart next time you're there, and see if you observe the same things I did.
Can be leaking intake manifold gaskets, which can sometimes be fixed by using Dexcool coolant. Can also be a head gasket.
Because the manufacturer used a red dye instead of a yellow or green dye. Its called Dexcool and it is that cooler so can tell them apart dont mix them, and use dexcool as called for by GM. The coolant is red rather than green because it is not regular antifreeze. This is a special GM coolant known as DEXCOOL. Dexcool is a phosphate and silicate free coolant, coherently making it a more stable and longer lasting product.
it uses dexcool coolant
no
Coolant. Most likely DexCool.
Dexcool and only Dexcool. It is an all aluminum engine.
The correct coolant is DEXCOOL it has an orange color to it. If your coolant is green the coolant has been changed. It has been found out that DEXCOOL was bad for Aluminum heads and gaskets. Best to switch to the green coolant.
Because they use an orange colored coolant in it.
Depends on what repairs you've made to the coolant system or the engine. It took me about 2.5 gallons when I replaced the lower intake manifold and it took about 1 gallon when I replaced the water pump. Use the Dexcool 50/50 and be sure to vent the coolant system for any trapped air and make sure the expansion tank cap is on tight. I had to prime the engine with coolant by squeezing the radiator hose when I replaced the intake manifold gasket. Note: There is no proven compatibility issue with Dexcool and the silicone used to form the lower intake manifold gasket. The issue with the 3.1 V6 is simply an engine and gasket design. Dexcool is used in millions of vehicles with no problems, so I'm inclined to say it's an isolated engine design issue with my 98' Malibu 3.1 V6.
Dexcool.
Original equipment was DexCool.
